Thanks for the great post, it helped were the eclipse plugin completely fails.
I have question with build.xml. I have a few library jar files that I use. I added them to the RAPC task using the <import> element <import location="/workspace/BlackBerry/MobileBlackBerry/lib/MathEvaluator.jar" />. Everything works fine until I run the application. I get the following exception "Entry point not found for Module MathEvaluator". Any idea what I need to do to get my app to rapc and run.
