Re: NoClassDefFoundError: Could not initialize class org.python.antlr.ast.Name

Hi Vincent

First things to check (and share) would be 

1/ PYTHONPATH and CLASSPATH
2/ Is it failing on the first invocation of jython or a specific bit of Python code? It looks like it is failing on an import. It would be good to clarify if simple scripts without imports work, just for troubleshooting.
