Re: java.lang.NoClassDefFoundError: org/python/parser/ast/VisitorBase

Hi All,

I've solved the issue.  I thought I'd write back and share the knowledge.

A cut and paste error in my code had lead me with duplicate import 
statements (doh).  Whilst this doesn't bother the jython interpreter, 
and isn't really illegal - just pointless, it screws up the creation of 
jar files.

A nasty gotcha - given that the error seen on execution of the jar has 
little or nothing to do with the issue.

Thanks for everyones input and help,

Phil.
