Here's the log when I get the import problem with Webware 0.6a1. Note that I
have added a context for a thing called SiteManager and it's inside that
package directory that one finds sites.xfd and sites.py. Meanwhile, the
XMLForms directory which contains the framework code resides in the same
directory as the WebKit directory - XMLForms and WebKit are siblings.
I'm running AppServer from inside the WebKit directory, which has always worked
in the past, and I don't have PYTHONPATH set. Here, the XMLFormsServletFactory
class is attempting to forward the request to the sites.py handler (servlet):
"""

"""
If I print the value of moduleName and directory I get this:
"""
sites /home/paulb/Software/Python/Webware/WebKit/SiteManager
"""
And if I interrupt AppServer and try this interactively, the following happens:
"""

>>>
"""
Sorry for the formatting, but I think the above communicates the events
adequately. Now, if I replace the imp.find_module and imp.load_module calls
with a call using __import__, it works:
"""
module = __import__(os.path.join(directory, moduleName), None, None,
[fullModuleName])
"""
In Webware 0.5.1rc2 I didn't need to change anything - regardless of whether I
set up a context or just dropped my resources into the Examples directory, it
just worked. But on 0.6a1, neither of these arrangements seems to function - I
get the above error either way.
Is it just me who is experiencing these bizarre events?
