Problem with Deserializer

Thu, 28 Oct 2004 02:33:46 -0700

Hi
I deployed a sample ejb webservice using Axis and i am using WSIF to invoke the webservice.
My webservice is going to return a complex java object(A value object).
The service was invoked successfully and the problem is with Deserializing the object ejb returned.
Its throwing error while Deserializing the object
 
My Deploy.wsdd
============
<deployment xmlns="http://xml.apache.org/axis/wsdd/"
