I am trying to use a MDB on WebSphere server (WSAD 5.1.2)

My process flow is as follows :
1.An object message is put in a queue (Queue A)
2.An MDB listens to Queue A, recieves the object, does some processing and
creates one or more XML messages which are put as TextMessages on another Queue(Queue B)
3.The whole process suceeds the first time but I also get the following exception on the console.

[8/21/06 21:03:05:125 IST] 6bace385 ServerSession W WMSG0031E: Exception processing JMS Message for MDB SPMessage, JMSDestination jms/SRSSPQueue : javax.ejb.TransactionRolledbackLocalException: ; nested exception is: com.ibm.ws.exception.WsEJBException

[8/21/06 21:03:05:219 IST] 6bace385 ServerSession W WMSG0036E: Maximum message delivery retry count of 0 reached for MDB SPMessage, JMSDestination jms/SRSSPQueue, MDBListener stopped

4. The deployment descriptor of my bean is as follows:



<message-driven id="SPMessage">
<ejb-name>SPMessage</ejb-name>
<ejb-class>com.heb.srs.webgui.ejb.application.forcast.sp.SPMessageBean</ejb-class>
<transaction-type>Container</transaction-type>
<message-driven-destination>
<destination-type>javax.jms.Queue</destination-type>
</message-driven-destination>
</message-driven>


5.After the first time the MDB doesnot work.

I believe something is wrong with the configuration.Anybody who has faced this earlier please help.

Thanks in advance.
