I have not yet look at this in depth, but I think the classes from lib &
classes are available as classes, but not as jython package namespaces.
You can test this by trying to load a class from withon the .py file
with java.lang.Class.forName(). I guess this should work, but the normal
jython import does not work.

As a temporary workaround you can add the java packages to the jython
package manager yourself with add_package.

sys.add_package("testpackage")
from testpackage import TestClass

It should be possible to force the jython package manager to search
these two wellknown places for java classes and packages. Perhaps by
setting python.packages.paths and python.packages.directories. Perhaps
by calling the package manager directly. More on later.
