References to Java projects in Jython?

Eclipse Ganymede SR1 (3.4.2)
Pydev 2725
I have an Eclipse workspace with several Java projects and one Jython project., and
I want to use some of my Java classes from Jython.
I added a "reference" to the Java project from the Jython project's properties dialog, but this does not make the java classes available. The import statement is
from com.troux.bpserver.standalone import DBConnectionInfoOracle, BlueprintServicesClient
At execution I get "ImportError: no module named troux"
What else do I have to do to get Jython to see my classes?
Aside from setting it as a reference, you also have to:
1. make the java project a pydev project (right click project > pydev > set as pydev project)
2. Configure that project pythonpath to add the .class files: project properties > pydev - pythonpath > add the source folder(s) that contains your .class files (this would be the folder just one level before your 'com' namespace).
Cheers,

I got around this by building the Java project into a jar and adding the jar to the global PYTHONPATH. Can a jar be added to an individual jython project?
That's also a solution (but if you're going to be developing that same project, it can be a bit troublesome, as you have to update your jar whenever you change your java code).
In the project properties: pydev > pythonpath, you can add a jar to just one project (see http://fabioz.com/pydev/manual_101_project_conf2.html )

I changed to your first suggestion and it works great. Thanks.
