Deployment namespace question

[Polly Powledge]

Hi,

I'm preparing my jython app for deployment as a standalone jar. I've
been following the advice in
http://wiki.python.org/jython/JythonFaq/DistributingJythonScripts and
in http://jython.extreme.st/talk/talk.html and have a couple of
questions about the namespace.

I've built the jar and am using a __run__.py script at the root to
launch my app. If I put my app in Lib, the __run__.py can import my
classes and run them successfully.

But I'd like to put my stuff in a folder two levels down from Lib, i.e.:

 Lib/myrootdirectory/mysubdirectory/foo.py

If I'm reading http://jython.extreme.st/talk/talk.html, I should be
able to do this by putting empty __init__.py files in myrootdirectory
and in mysubdirectory. Then if I do:

  from myrootdirectory.mysubdiretctory import foo

I should be able to instantiate foo in my__run__.py

However my jar file begs to differ. :^)  It gives me a TypeError: call
of non-function ('module'). And if I dump out my local dictionary
after my " from myrootdirectory.mysubdiretctory import foo", it does
indeed have it typed as a module and not a class.

Does anybody know what I'm doing wrong?

Thanks in advance,

Polly Powledge

I assume you have a class foo defined in foo.py.  To Python, foo.py
defines a module named foo, and your class foo is defined inside
module foo.  The class and the module are different entities, both
named foo.  Try:

from myrootdirectory.mysubdirectory.foo import foo

Then the unqualified name "foo" will refer to the class, not the module.
