[Jython-users] Jython, BSF, Cocoon2, and Tomcat

[Jason F. <jaf...@en...>]

Hello,

I'm currently trying to graft Jython into the Cocoon2 web publishing
framework using IBM's Bean Scripting Framework.  So far it has been a
straightforward process, so kudos to the Jython team.

If you're interested, check out xml.apache.org/cocoon and take a look at
ScriptGenerator.

Everything works great so long as all of the python code is within a single
script.  As previous posts have mentioned, as soon as I try to import from
another file jython complains about not being able to find the resource in
question.

The solution presented earlier (in the context of the JythonServlet?),
namely to use sys.add_package(), sounds like a good solution if you have
control of the servlet.  Unfortunately given the number of toolkits and
classloaders I'm working with I don't have this option.

I was wondering whether or not it would be possible to do something similar
to sys.add_package() from within a python script?  I tried this (naively)
and was told that "sys" wasn't a known name.  My idea is that I know, as
developer, that a class with a certain name is available somehow.

I'm not sure that this solution would work, given that Tomcat and Cocoon2
for sure have their own classloaders and the BSF might as well, but it's the
only one I can think of.  I *really* don't want to add things to my system
classpath if I don't have to.

As an aside, since I've been out of Java programming for so long, can I set
that various jython parameters programmatically as opposed to having to use
"-D" on the command line?

Thanks for any help!
