#20 jython "An internal error occurred during: "Lauching"

[Anonymous]

It gives this mensage when try to compile a simple Hello World.
When I used the PyDev plugin to write python app, the Hello World worked, but with the JyDT do not.
I read all the instruction, did all, but still show the mensage. (An internal error occurred during: "Lauching")

I also get this error. My Jython project consists of a single source file containing

if __name__ == '__main__':
print 'Hello world'

I can invoke it successfully from the command line using "java" or "jython".

My Eclipse version:

Version: 3.2.2
Build id: M20070212-1330 (Ubuntu version: 3.2.2-0ubuntu3)

My Jython version: 2.2b

My JyDT version: 1.4.15
