Hi Everyone,
I`m getting an error when my client tries to access the service end point class (which is also an Stateless Session Bean - EJB3). My Server codes returns a DTO object, I guess this exception is due to DTO object marshalling to XML. I am using Jboss 4.2.2 AS. Here is the error given below :

MainDTO which is getting returned back to client has a Collection of FormatDTO. If I try to remove the FormatDTO in MainDTO to test. Then the same error points to MainDTO. Please provide some suggestions to fix this issue.
