--------------------------------------------------------------
This is probably a simple one, but I'm stuck.  I call a new Web Service, queryByObject, which could return several different objects.

I have the below test case to return a User object.  If I change the method signature to return a User, it works.  If I leave it as an Object, I get 'javax.xml.bind.JAXBException: class pfcommon.data.User nor any of its super class is known to this context.'  Even with the XmlSeeAlso, it just won't add User into the schema.

Any help really appreciated!  I put in all the components that I felt were relevant.  JBoss 5.1.0.

Also, if there's anything else wrong in my style, happy to take comments, this is my first attempt at expanding my working EJBs to also be Web Services.

Thanks,
Tim
