Re: ImportError: No module named site

Hi Alex,

I am reporting back.  I believe I followed your recipe perfectly with
jython-standalone-2.7-b3 and now my application fails to start with a
different exception stack trace.  Perhaps my error is obvious to you.

Traceback (most recent call last):

  File "__pyclasspath__/site$py.class", line 553, in main
