Type System Manager Part 1

It has taken some time since I published Maintaining the Rational DOORS Next Generation type system in a configuration-management-enabled environment. Part 1: Manual procedures which is about this Jazz.net article.

I was very excited about it, because I was contributing to the effort myself. We finally have made progress and just released the next part. You can now read the article about Maintaining the Rational DOORS Next Generation type system in a configuration-management-enabled environment. Part 2: Automation.

So, what is that all about?

Type System Manager

I did some prototyping, and we experimented with different possible approaches for this automation. What we came up with is explained in the article above.

In summary, I created a prototype, lets name it Type System Manager (TSM), that can be used to automate the type system management, supporting the best practices identified in Part 1.

Example Execution Output

The prototype uses available public Doors Next Generation OSLC/REST API’s to perform the necessary tasks.

So I have been lucky to be able to do some prototyping and learn a lot about OSLC and REST API’s. The result is a prototype, that has a useful application, and is also a demonstrator for how to create automation using OSLC and REST API’s.

Usage of OSLC and REST API’s has been missing on this blog and this prepares the foundation for hopefully more examples, here in this blog, in the future.

Disclaimer and Download

I should not have to write this, but as this is the internet 8), so here goes: Any code downloadable or accessible in this post is provided as is, without support, and used at your own risk.

The code was developed in Java using Eclipse and is based on the Eclipse Lyo Client.

Thanks to IBM approving, the code was published as open source, under
 Eclipse Public License – v 1.0, in the incredible (mostly German speaking) Jazz Community and can be found here.

What is next?

The second part explains how the TSM prototype can be used and what it does and how. The next part is currently under review and will explain the details of the code, how it works, how to re-use and add to it. It also explains how to download and work with the code.


As mentioned in the article Comments, feedback, ideas, and experiences are greatly appreciated.

If you have questions, ask them in the Jazz.net forum instead of commenting on the article or this blog post. Tag the question as a Rational DOORS Next Generation question and add the tag: dng-type-system-management to mark it for the reader.


As always I hope that the artifacts created for this blog will useful for the Jazz user community out there. Feedback, also usage, is greatly appreciated.


RTC Extensions Workshop – How to fix SSL protocol errors preventing connection to Jetty Debug server

Since some time now I started to run into a blocking issue with the Extensions workshop. I was not able to find a solution so far. Today a colleague saw the same and asked for help. Here what I found.

Problem: the browser prevents connecting to the Jetty server

When launching the Jetty Debug server, everything seems to be fine. You can even connect with an Eclipse client to the server. However, if you try to follow the description in the Extensions Workshop and you try to connect with a browser to https://localhost:7443/jazz/admin you see a screen like the one below.

SSL Error_1

In Chrome the error claims

This site can’t provide a secure connection localhost sent an invalid response.

Try running Windows Network Diagnostics.


Firefox is even more alarming and says

Secure Connection Failed

An error occurred during a connection to localhost:7443. Peer reports it experienced an internal error. Error code: SSL_ERROR_INTERNAL_ERROR_ALERT

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem.

Edge complains

Can’t connect securely to this page

This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner.

Try this:

Go back to the last page

It looks like the usual SSL issue with the standard certificate, but it actually is not. It does not allow you to proceed and add an exception to connect to the web site.

You are basically stuck.

I had the same issue yesterday with 6.0.5 and 6.0.6 and I knew it was working very recently – when I moved to my new laptop. I searched the internet and was not really sure about a solution still. The answers pointed at version issues and certification mismatches. So I decided to switch the Eclipse environment to a current JDK and that solved the problem. I have tried it with RTC 6.0.5 and 6.0.6 but I am pretty sure it would work with other versions as well.

Please note that the Extensions workshop suggests to use the same JDK the Server uses. I think since Browsers have recently increased their security measures, this is no longer true.


Here how to fix the problem.

  • Download and install a recent Java JDK/JRE that is compatible with the version of the RTC SDK you are working with.
    • 6.0.6 is compatible with Java 1.8
    • I use a JDK because there are other development tools that require a JDK
  • Open the Eclipse server development workspace
  • Open Window>preferences
  • Type JRE and navigate to Java>Installed JREs
    • Add the new JDK/JRE
    • Select the JDK/JRE as active click Apply and CloseNewJDK
    • Navigate to Java>Installed JREs>Execution Environments
    • Select the Execution Environment with the matching version
    • Select the new JDK/JRE as active click Apply and CloseExecEnvironment
  • Launch the Jetty debug serverLaunch

Now try to login to https://localhost:7443/jazz/admin again. You still get an error, however the browser provides the Advanced link to continue connection to the site.

SSL Error_2

The different browsers display it different, but the concept is the same for all of them.


Recent increases of browser security checks and invalidation of certificates requires to update to recent versions of the Java JDK/JRE to be used with the Extensions workshop. As always I hope that this helps people out there.

Maintaining the Rational DOORS Next Generation type system in a configuration-management-enabled environment. Part 1: Manual procedures

I have been involved in efforts around the configuration management features in the IBM Collaborative Lifecycle Management and Continuous Engineering Solution. These Configuration Management capabilities are a completely new approach to versioning and variant management across the different disciplines such as Requirements Management, Quality Management, Modeling, and Software Change and Configuration Management. We realize that there is a whole new area for best practices and our subject matter experts have been working on creating necessary information for some time. There is already some content available on Jazz.net. For example from Kathryn and Tim in the Deployment Wiki.

As we learn we try to create more content, involving more SMEs. Today we published the article Maintaining the Rational DOORS Next Generation type system in a configuration-management-enabled environment. Part 1: Manual procedures.

I am currently working on Part 2. If you want to know what that could be, check the article.

I am pretty excited, I hope to publish soon!

Jazz Community Contributions

The Jazz Community starts sharing their tools here: http://jazz-community.org/. The code for their tools can be found here.

There is a very active Jazz user community of members of several companies in Europe that are heavily using the Jazz products such as Rational Team Concert, Rational Quality Manager and Doors Next Generation.

The community members try to meet to share their experience with using, administrating and running the Jazz tools in their environments. It became clear that the different companies and community members face similar challenges and that it would be beneficial if they could share tools they created to make running such an environment easier.

The community has now started sharing their tools in this community project and in this code repository.


Some of the tools have already been shared on other sites. I have linked the ones I am aware of to the Interesting links page in the ‘Extensions Provided by the Community’ section. These are the ones I am aware of (and the code for some of them is already available in the community repository):

I am looking forward to see more community created tools soon. Visit the community to find out what they have to offer. The code for their tools can be found here.

Last but not least, a special thanks to Dani for getting this awesome user groups started and for the members of said community for their spirit, engagement and willingness to contribute and help each other. You know whom I address here!

The RTC SDK is about to change in 6.0.3

Since some time now, the RTC and Jazz Development teams are in discussion how to cope with the version compatibility requirements driven by Eclipse clients and the server API. In RTC 6.0.3 the SDK is about to be split into separate SDK’s for the Eclipse client and the Server. This will impact how the development environment needs to be set up and how extensions are developed. I will try to share a summary of what to expect here. I have so far only been able to experiment with development builds, there has not been an official release of the SDK for 6.0.3 yet.

Download the new workshop

Update * the new Extensions Workshop is finished for a while now. it can be found at the original Rational Team Concert Extensions Workshop location.

Why splitting the SDK?

The RTC Clients have been based on Eclipse 3.6 for a considerable amount of time now. This has been the case for the Jazz Servers as well. However, there is pressure on the server infrastructure for the need to support Eclipse 4.4.x and higher. On the other hand there are client applications that RTC needs to integrate with, that are lagging behind in adoption of new Eclipse versions.

As described in What API’s are Available for RTC and What Can You Extend? the RTC SDK currently contains the RTC Server API, the RTC Common API and the RTC Client API in one delivery. The RTC Common API is part of the RTC Server API as well as the RTC Client API. This is a potential problem when shipping the SDK and trying to keep the Server compatible to Eclipse 4.4.2 and above and being compatible with Eclipse 3.6 clients. As it looks, the RTC SDK will be split into two parts.

  1. A RTC Server SDK bundling the RTC Server API and the RTC Common API compatible with Eclipse 4.4.x and higher
  2. A RTC Client SDK bundling the RTC Client API and the RTC Common API compatible with Eclipse 3.6.x and higher

Impact of splitting the SDK

The split has various impacts on how extension development will now work. Please find below a short summary of changes that I have found necessary to perform the workshop.

Changes to section: 1.1 Download and Unzip the Required Files from jazz.net

The Server SDK Target Platform now requires an Eclipse 4.4.2 or higher. You can download the base Eclipse 4.4.2 client here. For example download the version Eclipse IDE for Java EE Developers. Install the client similar to described in the workshop. Then download the RTC Eclipse Client p2 install package and install this into your Eclipse 4.4.2.

In the Feature Based Launches download the new launcher442.zip. Unzip the zip file, browse to the enclosed JAR file and copy that into the dropins folder in the Eclipse client.

You might want to consider to do the following changes to the eclipse.ini file.

  • Add a section -vm with an additional line for the java virtual machine to use. If you run Eclipse with a different JVM, e.g. from Oracle, consider to specify a JRE or JDK that is compatible with the one that ships with RTC. This vm would also be used in the workspace setup section.
  • Add -showLocation in the org.eclipse.platform section; this shows the Eclipse workspace path in the upper border of the Eclipse client as below


    This makes it possible to actually work with multiple workspaces and knowing which an Eclipse instance is responsible for.

  • A vmargs argument -Duser.language=en to make sure you get a consistent language in the menus if you want.

The image below shows the changes in my caseeclipse-ini-2016-11-07_11-09-02

Changes to section: 1.2 Setup for Development

Once the SDK is split into two parts the Rational Team Concert Extensions Workshop can no longer be performed using just one Eclipse Workspace. An SDK is set up as a Target Platform in the Plug-in Development section. Since the SDK’s are now split, it is necessary to have two target platforms. Since it is not possible to have more than one Target platform active in one Eclipse workspace it is not possible to launch a server for debugging while running an Eclipse client from the same workspace.

The RTC Extensions workshop will have to be changed to set up two separate workspaces.

  • One workspace will have to be set up with the RTC Server SDK as active Target Platform, for example using the path: C:\RTC603Dev\Workspaces\Dev1\Server
  • The other  workspace will have to be set up with the RTC Client SDK as active Target Platform, for example using the path: C:\RTC603Dev\Workspaces\Dev1\Client

Both workspaces will require to be set up as described in the RTC Extensions workshop document in section 1.2 Setup for Development.However, you will set up different target platforms in this step. Using the Server SDK for the server development workshop and the Client SDK for the Client development workspace.

Please note, it is a good idea to configure Eclipse to use an external browser as well in this step.

Changes to section: 1.3 Setup the RTC Tomcat Server

I am modifying the WorkshopSetup tool and data to setup the RTC project named RTC Extension Workshop to support an easier setup for the two workspaces. Basically two separate RTC Repository workspaces will be available. One will provide the launch, the configurations and the components needed to develop the RTC Eclipse server extension part of the workshop. The other one will provide the launch and the components needed to develop the RTC Eclipse client extension part of the workshop.

As long as this is not yet available it is possible to start with the existing setup tool and the related repository workspace and to load that into the two Eclipse workspaces. One workspace has to be set up with the RTC Client SDK will be used for development of the client part. The other with the RTC Server SDK set up is used to develop the server parts. When performing the workshop it will be necessary to work with the two workspaces and use one for all the server related tasks and the other one with the client related tasks. When Accepting changes into these workspaces it is necessary to understand what is part of the client and what is part of the server or what is shared. The image below shows what belongs to what.

  • The parts colored in blue are only related to server development
  • The parts colored in yellow are only related to client development
  • The uncolored parts are related to client and server development


Make sure to keep in mind which parts of the code are relevant for what. As an example, the project net.jazz.rtcext.workitem.extensions.ide.ui will not compile in the server development workspace. Similarly the net.jazz.rtcext.workitem.extensions.service project will not compile in the client development workspace.

Changes to section: 1.4 Complete Setup of Your RTC Eclipse Client

After Loading the repository workspace you have the choice to split the information into a sever part and a client part. For example you can duplicate RTC Extension Workshop Configuration and create one that only contains the client launches. Or you keep everything as it is and basically close the project areas you don’t need and ignore launches not needed. This is the easiest approach until a new Extension Workshop is available.

The initial step of copying the files services.xml and scr.xml is only needed in the server workspace. So when copying and importing, copy the files services.xml and scr.xml from your server’s ccm application in the installs\JazzTeamServer\server\conf\ccm folder into the RTC Extension Workshop Configuration project into the folder conf/jazz in the server development workspace.

When importing the plugins and features import the following into the server workspace:

  • com.ibm.team.common.tests.utils
  • com.ibm.team.jazz.foundation.server.licenses.enterprise-ea (or com.ibm.team.licensing.product.clm)
  • com.ibm.team.licensing.product.rtc-standalone

When importing the plugins and features import the following into the client workspace:

  • com.ibm.team.rtc.client.feature

Other considerations

As already mentioned, make sure to keep track which workspace you are working in and keep in mind that the server development part will not work in the client development workspace and vice versa.

Just Starting With Extending RTC?

If you just get started with extending Rational Team Concert, or create API based automation, start with the post Learning To Fly: Getting Started with the RTC Java API’s and follow the linked resources.

You should be able to use the following code in this environment and get your own automation or extension working.


We have major changes coming up in the RTC Extension development area. The RTC Extension workshop needs to be adjusted and parts of the workshop lab needs to be reorganized and rewritten. This post explains what to consider for experienced users. Once there is an update to the Extension workshop lab material this post will be updated.

As always, I hope this helps users out there and saves them some time.

Alien Skies II – JavaScript Yet Another Computer Language?

I tried to look into Web UI Development, especially in the context of RTC Extensions like dashboards and the like several times in the past. I couldn’t get it to fly. It was a total disaster so far. I couldn’t understand how all that works and what the fuzz was all about. The more I looked into it, the more confused I was.

Surprisingly, looking into Doors Next Extensions seems to have revealed the missing link(s) I needed to better understand the whole topic around JavaScript. I have talked to other people who had similar issues with JavaScript, so I hope it is worth sharing my thoughts here.

I am well aware that the topic and my approach to it could be very controversial. If you like to disagree with any of my assessment, please feel free to do so in the comments. I rarely dismiss comments, but please be aware that the comments in this blog are moderated xD.

I have a book about JavaScript, but I rarely see JavaScript like it is described in that book. So, how does this JavaScript stuff work?

Its Not The Language

As far as I can tell, the language itself does not really matter that much. The language syntax of JavaScript is very similar to other languages e.g. such as Java. The Language has inheritance mechanisms, the language can support event based, asynchronously processed and functional aspects. All in all, a collection of properties that are shared across several language families.

There are some issues with the language (at least from my, still uneducated, point of view). It is not type safe to get started. While this is very flexible it is also asking for trouble in my experience. JavaScript is very dynamic and does not get compiled. A lot of issues will be seen at run time and not during coding.

Anyway, to have a common language with a common syntax and semantic is probably useful if you have to switch the domains often. At least you don’t have to learn a new language over and over.

Its Not The Development Environment

I am missing a good library handling and context sensitive editor support. There might be some cool development environment out there, but it has eluded me so far. Any suggestions are welcome, as always.

I have seen the first computers making their appearance in schools. With enormous keyboards with two lines of 40 characters to display. Nothing one would associate with a computer today. I was lucky enough to be able to write my first own programs on Commodore PET, VIC-20, 64 and on the first IBM PC’s. Ignore the first program on a Texas Instruments calculator with 32 programmable steps. I have developed without debugger, because there were no debuggers available or not affordable e.g. you could buy in circuit debuggers for  embedded systems but that was sometimes unaffordable even for companies back then.

I have seen bad development environments and debugging by printf. It is not that bad with JavaScript, in browser based applications. It basically depends on what the use case is, if there is a good debugging environment available or not.

Feeding The Confusion

I am usually pretty good in spotting patterns. Looking into the JavaScript domain, I had a hard time finding the basic ones. A lot of the confusion I felt is also, in hind sight, probably related to the fact that there is not just one JavaScript. There are multiple. And they are used in different ways and using different patterns. In addition to that the expression JavaScript is often used in contexts, where it would probably be better to talk about Web or JavaScript libraries or frameworks instead.

  1. There is the JavaScript that runs in browsers. This JavaScript usually works together with CSS and HTML. It is used to create dynamic content and presentations in the Web to be able to provide more or less usable UI’s in a browser, designed to show more or less static HTML documents. The JavaScript engine is built into and shipped with the browser and there are different engines and development environments for different browsers. This type of JavaScript basically requires to understand how JavaScript, HTML and CSS work in combination and how to control their interaction.
  2. Browser based JavaScript is integrated in several different frameworks and tool kits such as Ajax/Dojo and others.
  3. There is NodeJS, which claims to be Java Script and actually is sever side JavaScript processing and a ton of libraries and frameworks that are available for it. The only common part I can identify here is the language that is used. I did not look into the details however, so maybe there is more e.g. the run time used could be one of the common ones.

So when I started to look at the Doors Next Extensions which said JavaScript, I realized quickly, that there were constructs in the examples that I had never seen before in any JavaScript example. The normal pattern again, every time I looked at something with JavaScript inside and thought I had some basic knowledge already, I saw something different. This time however I was able to figure out what I was missing and this seems to help with all the other cases as well.

The Doors Next Extension Mechanism

The Doors Next Extension mechanism is based on JavaScript, HTML and CSS. The API supports TypeScript which provides with a more type safe and compile like way of developing JavaScript. The Doors Next API itself comes with a Typescript interface definition. Some of the examples that are provided use jQuery a JavaScript based library and framework. The latter means that the extensions look a bit uncommon.

Uncommon Common

To some extend this seems to be fairly typical for my experience with JavaScript. Almost every solution I have seen has some common part that can be found in other solutions. But looking across all the examples there is only a tiny common core, which often is basic JavaScript functions. If the JavaScript based solution deals with UI’s, there is usually the common CSS and HTML, if it does not focus on UI’s this is missing. Since there are so many frameworks and libraries, Java Script based solutions can look very different and it is important to understand the detailed frameworks and resources that are used in the specific example.


Granted, it took a while for me to come to terms with JavaScript,  but looking into the Doors Next Generation Extension Mechanism provided me with some important insight. This will help me to understand these technologies in other contexts as well. I am looking forward to playing with Doors Next Extensions and add the results to this blog.

Alien Skies – Peeking Into Doors Next Extensibility

I started a recon mission into the alien territory of Doors Next extensions recently and almost lost my way.

Doors Next is one of the products I am responsible for. I have some experience with requirement management and I understand Doors Next usually good enough to find my way, but I am way more familiar with RTC, especially since I did a lot with its Java API and extensions. So I thought if this is similar to the situation with RTC, capabilities to extend Doors Next will be in high demand soon and I better get my hands dirty and into it. Since the language available to extend Doors Next is JavaScript, this looked also like a good opportunity to have some more exposure to JavaScript.

Update, a nice summary of RDNG API’s can be found here.

First Steps – Look into the documentation

So I browsed through the documentation a bit to learn what there is to learn! Other than me, please start with reading the most recent version of the documentation. This will save you detours like looking at WAS Liberty Profile and publishing data. I followed the guidance and played around with the simple examples and the more complex ones provided. I became adventurous and wanted to modify the Hello World open social gadget example and create one that should be published in the widget catalog along with the other examples. The example worked as open social gadget already and I thought, I could use it as widget as well.

That did not work so good. Why? If I used the same xml code the open social gadget showed and the Dashboard widget showed a blank content.

The Widget

This is how the basic widget looks like. All the rest such as CSS, JavaScript and the like can be added to it based on this structure.


The Open Social Gadget

This is how the open social gadget looks like. I tried to spot what the difference was for a long time. Until I finally noticed that the difference between a working gadget and a working widget is the tag that the open social gadget has and which is missing in the widget..


It took me quite some time to figure out what the problem was. Embarrassing, but on the other hand it shows again, that tool extensions, even the smallest, are complex business. Maybe there are better ways to debug these kinds of issues. Compared to RTC Java Extensions I felt like back in time, trying to debug C and Assembler with printf…..

See this site for some additional introduction into open social gadgets.

Deployment Structure

Similar to my description in Publishing XML and Other Data With the WAS Liberty Profile  the extensions where deployed in the apps folder like this:


Compared to RTC Extensions, this is a relatively simple and accessible structure. As mentioned by Guido, in an enterprise context, it would make sense to have your own web server to publish the extensions. This would allow to have a more fine grained control about who can change what.

It would be possible to use a RTC Build workspace to publish these extensions. I think there is a need to come up with some naming pattern for the extensions, in order to avoid chaos and confusion over time.

This has been challenging in the past and I assume it will stay challenging. The structure above has a css folder, as well as a JavaScript folder just in case. There is also a need for some more documentation and the like.


Doors next has means to extend its capabilities. Provided some fundamental knowledge, this should allow for a lot of the automation needed in enterprise environment. My first steps into this alien territory where a bit shaky, but all in all, I think I now have the basic understanding where and how to get started with more complex extensions.

Publishing XML and Other Data With the WAS Liberty Profile

Since CLM now ships the WebSphere Application Server Liberty Profile as default, you might want to be able to publish XML and other data similar to the easy way that was available in Tomcat, by just using the application server that is available. This avoids having to set up an additional Web or application server.


Sometimes it is necessary to provide access to some files using the HTTP/HTTPS protocol.

This is interesting for the Process Enactment Workshop, or if you want to publish your own XML data to be used with HTTP Filtered Value Sets, host custom Doors Next Extensions, or if you want to publish Build results.

It is convenient if there is already an application server available to host these files there and make them accessible, instead of having to set up a web server. This especially holds if it is necessary to provide the data using HTTPS, and not HTTP, because browsers these days reject to process content that is mixed from HTTP and HTTPS sources. The latter is important for Doors Next Generation extensions. Not having to set up a new server also avoids having to create a trusted certificate for it. It reduces the additional failure point, backup and maintenance and provides URI stability as well, since you don’t want to change the URI for the CLM applications hosted anyway.


With Tomcat, it was relatively easy to do that, by just adding a folder under \tomcat\webapps and placing your files there. Assuming the folder name is myfiles, Tomcat then provides the files with the public URI root https://serverpath:port/myfiles/fileName.

Another way was to simply drop the file into the tomcat/webapps/ROOT/ or a sub folder, which has the same effect.

Is there a similar way to achieve this with the WAS Liberty Profile shipped with CLM?

Example Scenario

Lets assume, like in the scenario explained in Publish and Host XML Data Using Tomcat – The Easy Way, we want to publish a file makers.xml to be accessible with a context root PEWEnactmentData on the server with the public URI root https://clm.example.com:9443/.

The expected outcome is to be able to access the XML file content using the URL https://clm.example.com:9443/PEWEnactmentData/makers.xml.


There are two relative simple solutions for WAS Liberty. The solutions below are based on information from Lars, one of our WebSphere experts and the IBM WebSphere Application Server Liberty Profile Guide for Developers.

For WAS Liberty Profile, all solutions require to deploy an application. There are several ways to create and deploy an application in WAS Liberty Profile.

  1. Deploy an application in some folder and declare the context root and location of the application in the server.xml or specific location XML file
  2. Deploy an application in the dropins folder; for this to work, it is necessary to make sure the application server has the dropins monitoring enabled for this to work

Deploying an application in this context means

  1. Create a folder with some contend in a location (or copy the folder into the location)
  2. Deploy a compressed folder with some content

Please note: Any changes to any of the server configuration XML files are automatically picked up be WAS Liberty Profile. There is no need to reboot the server for the steps below to work.

1. Deploying an Application – Standard

The trick in this solution, is to pretend to deploy an uncompressed Web Application such as a WAR file. It is obviously possible to create a real WAR file or the structure that is contained in it, but that is not really necessary. See the last section here if you are interested in deploying the application as compressed WAR file.

1.1 Deploying the Application

The only thing necessary to trick the WAS Liberty Profile into making the data available with a correct context root is to create a folder with the context root as name and an extension .war, and to make the application location known in an XML file.

In the default setup of WAS Liberty Profile with CLM, after the first launch, all installed CLM applications end up in the folder <Install Folder>\server\liberty\servers\clm\apps. The screen shot below shows this structure.


The applications are deployed as compressed WAR file and have been extracted to a folder with the name of the application. As an example the CCM application (RTC) came shipped as ccm.war.zip and was extracted to a folder ccm.war. The context root of the CCM application is ccm, which is basically the name without the extension war. The same pattern holds for all the other applications.

It is possible to create a folder to host the files to be published. The folder should be named <context root>.war to result in an application with the desired context root.

Files within this folder will be available with their file name.

A file in that folder with the name <filename> will be accessible as <public URI root>/<context root>/<filename>.

If the files are within sub folders, the folder path within the root folder and the file name compose the file name part of the URL. For example, the root folder has a sub folder names myfiles and a file test.xml in it, the file is accessible as <public URI root>/<context root>/myfiles/test.xml.

In our example with the given public URI root being https://clm.example.com:9443/, the folder name <context root> being PEWEnactmentData and <filename> being makers.xml the URL would be https://clm.example.com:9443/PEWEnactmentData/makers.xml.

1.1 Declaring the Application Location

The WAS Liberty Profile needs to know which application has to be published and where to find its resources. WAS Liberty Profile defines an XML element to declare which application is located where. The element is <appliction…./>. It supports various attributes and can come in many different forms. The most important attributes are

  • id: Must be unique and is used internally by the serve
  • location: The path to the application resource
  • context-root: The context root of the application
  • name: The name of the application
  • type: Specifies the type of application (war or ear)

The location and ID is required and either the name equal to the context root, or the context-root can be provided. The type can be omitted. I did not provide the ID and it worked for me, but since the server requires it, it should be provided. Use the same value as the name or context root for the ID.

It is necessary to add the application declaration to the server configuration for example by adding it to the server.xml file. In a CLM deployment a file appliction.xml is included in the server.xml, declaring all the applications and it makes sense to use that file instead.

Save the xml files after any change to activate the new setting. The server will pick up the change.

2. Deploying an Application – dropins

The WAS Liberty Profile has the capability to monitor a special dropins folder on a regular basis. If new content is detected, it is automatically made available by the server. The automatic monitoring needs to be enabled for this to work. A standard CLM deployment disables the monitoring to reduce server load.

2.1 Deploying the Application – dropins

In a default CLM install the dropins folder is located here:

<Install Folder>\server\liberty\servers\clm\dropins

Create a folder named <context root>.war in the dropins folder and add the files to publish. After detecting the addition, the files will be accessible like explained in 1.1.

The folder <Install Folder>\server\liberty\servers\clm\dropins should now look like below.

Published application with file

2.1 Enable Automatic Monitoring for Dropins

The automatic monitoring of the dropins folder is disabled for a standard CLM setup with WAS Liberty Profile. This saves processor cycles and I/O for the server operation. It has to be enabled once in the server.xml file for this solution to work. Find the XML element <applictionMonitor> and change the attribute dropinsEnabled from “false” to “true” and save the file. The image below shows the changed configuration file.

Enable Dropins Monitoring

The attribute pollingRate determines how often the server checks the location for changes. Adjust the value to your needs.

Save the server.xml file after any change to activate the new setting. The server will pick up the change.

The XML file content should now be accessible.

Example 1 – Standard

In the example we want to publish a document with the URI https://clm.example.com:9443/<context root>/makers.xml, where <context root>=PEWEnactmentData. The public URI root is already given by the server set up.

1.1 Create the “Application”

As first step create the application. Create a new folder named PEWEnactmentData.war in the folder <Install Folder>\server\liberty\servers\clm\apps. The folder could be created anywhere, but it makes sense to put it where the other applications are. If it is necessary to use a different folder, for example to allow other users to modify the content, place the folder in a different location and note the path. The path to the location will become important in the next step.

Put the files to be published underneath this folder. In the given example, put the file makers.xml into the folder.

The folder structure should look like the image below:

New Application folder

1.2 Publish the “Application”

The WAS Liberty Profile needs to know which application has to be published and where to find its resources. WAS Liberty Profile defines an XML element to declare which application is located where. The element is <appliction…./>. It supports various attributes and can come in many different forms. The most important attributes are

  • id: Must be unique and is used internally by the serve
  • location: The path to the application resource
  • context-root: The context root of the application
  • name: The name of the application
  • type: Specifies the type of application (war or ear)

The location and ID is required and either the name equal to the context root, or the context-root can be provided. The type can be omitted. I did not provide the ID and it worked for me, but since the server requires it, it should be provided. Use the same value as the name or context root for the ID.

The element can be put into several places. In a CLM installation, by default, the applications are declared in the file

<Install Folder>\server\liberty\servers\clm\conf\application.xml

The file is included in the file <Install Folder>\server\liberty\servers\clm\server.xml. It would be possible to place the application declaration in the file server.xml, but it seems to make more sense to put it into the file application.xml instead.

Add lines

<!–  My Application –>

<application id=”PEWEnactmentData” name=”PEWEnactmentData” location=”${server.config.dir}/apps/PEWEnactmentData.war”/>

to the file application.xml and save the file.

The file should look like below:

Declare new Application

In this case the location is relative to the server configuration folder which n our case is <Install Folder>\server\liberty\servers\clm\. The location could really be anywhere. If it is necessary to include a folder that, as an example, can be accessed by regular users, you could change the location to somewhere with less read and modification restrictions.

After the save of the application.xml, the published XML file should be accessible using the URL https://clm.example.com:9443/PEWEnactmentData/makers.xml.

The image below shows the browser access.

2. Deploying an Application – dropins

In the example we want to publish a document with the URI https://clm.example.com:9443/<context root>/makers.xml, where <context root>=PEWEnactmentData. The public URI root is already given by the server set up.

2.1 Create the “Application”

As first step create the application. Create a new folder named PEWEnactmentData.war in the folder <Install Folder>\server\liberty\servers\clm\dropins.

Put the files to be published underneath this folder. In the given example, put the file makers.xml into the folder.

The folder structure should look like the image below.

Published application with file

Assuming the automatic application monitoring is enabled, the file should be accessible after the next polling cycle, (at least after waiting the full pollingRate). If automatic application monitoring is not enabled, enable it as described in 2.2 and save the configuration file.

The XML file content should now be accessible using the URL https://clm.example.com:9443/PEWEnactmentData/makers.xml.

Deploying Compressed Folder Structures

It is also possible to publish real WAR, EAR similar to the way described above. For example create a WAR file as described in Publish XML Data Using Tomcat – Hotfix for The Process Enactment Workshop and attached to that post. Deploy the compressed WAR file, for example PEWEnactmentData.war in the dropins folder or declare it as an application and put it onto another location like explained below. This automatically deploys the application and makes the contained files accessible.

Just zipping the folder structure we created above into a zip file, name it PEWEnactmentData.war and trying to deploy does not seem to be working however. The WAR file needs to provide required supporting structures in this case.

This post shows how easy it is to publish supporting files on the WAS Liberty Profile. This is important if you want to host custom Doors Next Extensions, or if you want to publish your own XML data to be used with HTTP Filtered Value Sets, for the Process Enactment Workshop and it can possibly also used with Build result publishing. In the latter case, you would likely publish a root folder that contains all the build results.

As always I hope this post has some value to users out there, or is at least interesting to read.
