Re: [Jython-dev] Jython glob/re modules

[Seshu N. <Ses...@sd...>]

Robert,

Thank you very much for suggesting more than one way to solve this issue.
As you rightly guessed,  I moved the jar file elsewhere and .py files in
installed lib directory are not seen by the Interpreter. Copying the lib files
(such as glob.py) into right location solved the problem!
Your code examples are really good to understand the issue.

However, since the glob module doesn't form part of jython.jar, how could this
be supplied to user/customer (not that I'm intending, but just  curious to know!)

Thanks,
Seshu
