CORBA MARSHAL 0 Exception with second call of ejb-method

[Rudolf Schmidt]

Hi,
i got the following problem:
I have a Session Bean which has a method:
getDocument() { return new org.jdom.Document(new Element("test")); }
The method is accessed in a servlet which resides in the Websphere Test Environment (WTE) of Visual Age. The first Time getDocument() is called everything works fine, and the document is passed to the servlet. The second time (and all follow-ups..) the following exception is thrown:
CORBA MARSHAL 0 No; nested exception is: org.omg.CORBA.MARSHAL: Unable to read value from underlying bridge : Unable to read value from underlying bridge : Serializable readObject method failed internally minor code: 0 completed: No
If I restart the WTE, I can again make just one call, while the second leads to the exception.
Strange is, that everything works fine with the Testclient from wte. In the Testclint I can make multible calls to the Session Beans Method.
The JDOM API is fully serializable.
Help would be very appreciated
