JSystem

are you activating run.bat or runBase.bat? You should activate run.bat.

If this is what you are activating then I don't understand the root cause of your problem. The issue is however is here: -Djsystem.main=%JSYSTEMMAIN% For some reason (which I don't understand), the JVM property jsystem.main doesn't get a valid class name value. It should get it from the environment variable JSYSTEMMAIN which is defined in the run.bat I hope this information will give you a direction.
