My guess would be that it doesn't like the Object[] return type -
I don't think that Object is a valid RMI-IIOP type since it's not
serializable or remote. Now, one might assume that the instances you
actually return are valid... Can you create some sort of intermediate
interface for the things you return which extends Serializable or
something like that?
This is just speculation, though, because the problem could also
be in DataObject, PageDescriptor, etc.
In any case, it's possible for you to get this message when your
beans still work fine. So even if there's a violation of the RMI-IIOP
spec, you probably won't notice it unless you try interoperating with a
CORBA server or something.
