I've had to do similar tricks with PyCharm and Netbeans.  I believe that the IDE has its own set of paths, and it does not use the paths set up by the operating system, etc.  Sometimes setting paths up within an IDE can be tricky!

Sorry I do not have any specific answers for your question.

I did resolve my import of the org.python.core package, by finding a posting to add the jython.jar file to my External Libraries path.

But why??

As part of the Eclipse PyDev set up, I had to set up the Jython 2.5.2 which clearly points to the jython.jar file.

Can someone help me understand the foundation upon which I need to specify this jython.jar in both the interpreter AND the external libraries?

Kind regards, Marc
