EWM/RTC Extensions Workshop works with EWM 7.0.x


As published in Issues with the EWM/RTC Extensions workshop in 7.0.x versions, there was an issue that caused the RTC Extensions Workshop to fail starting a Eclipse debug client in Lab 1.9. The problem and how it was caused has been found. I have just tested the RTC Extensions Workshop Lab 1 with the new EWM Client SDK (7.0.1 and 7.0.2) and it works now as it should. I will update my previous post.

While running the test, I found that I had to increase the maximum heap size for the launch [RTCExt] Jetty RTC Server, because the JUnit Test that is run to create the test database, ran out of heap memory. I doubled the value from -Xmx256M to -Xmx512M and the error was gone.

Increase the available heap

The fix is only in the EWM/RTC Client SDK, so it is only necessary to download that again.

Please note that due to the name changes and newer versions of Eclipse, there might be some small differences between the screen shots in the RTC Extensions Workshop and the newer versions. However, they are so minor, it should not be an issue. I am currently looking into updating the current Extensions Workshop material with small changes to help guide the user with these changes.

The issue with server debugging explained in Issues with the EWM/RTC Extensions workshop in 7.0.x versions, is still apparent in 7.0.2. The suggestion to change the JRE of the server in that blog post holds.

As always, I hope that my posts here help the Jazz user community and save them some time.
