Proxy Error

[stevek]

I get the error below when I try to return an object from a session bean (using the home/remote interface). The object is returned from OJB and contains objects within it that are retrieved by OJB references. If I just return the top-level object (by removing all the references to other tables so OJB does not retrieve the other table entries) it works. Any ideas?

Thanks for any help

What is the undeclared throwable?

You don't show the full stacktrace.

I think this is all of it:

java.lang.ClassNotFoundException: org.apache.ojb.broker.util.collections.ManageableVector

I guess you don't have that class in the client's
classpath.

Thanks, I see the "class not found" exception now. I guess I did not look far enough down the trace. Now I need to figure out what OJB is doing.
