So, now I've got two different modules that require different

How do I call initVM() appropriately?
That's actually documented line 251 in jcc's README file.
initVM() returns an env value which you can pass on to later initVM() calls.
The code below is supposed to work but has never been tested in a real
situation:
>>> import os, foo, bar
>>> env = foo.initVM(foo.CLASSPATH)
>>> bar.initVM(classpath=os.pathsep.join([foo.CLASSPATH, bar.CLASSPATH]),
env=env)
You can also get this env value by calling getVMEnv() as in:
>>> import foo
>>> foo.initVM(foo.CLASSPATH)
>>> import os, foo, bar
>>> bar.initVM(classpath=os.pathsep.join([foo.CLASSPATH, bar.CLASSPATH]),
env=foo.getVMEnv())
If the classpath resetting doesn't stick, try setting it to both in the
first initVM() call. I'm a little unsure about the dynamic classpath
changing of a running VM. I do it in jcc by setting the java.class.path
system property.
Let me know if this actually works...
Andi..
