Web Service Deployment Exception

Question

Hi All,
I have created a Stateless session bean in which i am accessing JPA entities.
In my session bean I have two methodes and i exposed those methodes as web services. I deployed this ejb project into server and search for my web service in Web Service Navigator. I didn't find my web service. Then I observer server logs. It is throwing a Web Service Deployment exception.
Code:
@WebMethod(operationName="readChannel", exclude=false)
     public ReadChannelResMsg readChannel(@WebParam(name="readChannelReqMsg")
     ReadChannelReqMsg readChannelReqMsg) {
          ReadChannelResMsg readChannelResMsg=new ReadChannelResMsg();     
          readChannelResMsg.setChannel(channelDao.findById(readChannelReqMsg.getChannelId()));
          return readChannelResMsg;
Exception:
[ERROR CODE DPL.DS.5030] Clusterwide exception: [server ID 3324150:Exception occured during web services deployment. Unable to generate serialization framework for web service ProgramPlanWS, application hcl.com/longterm_plan_ear.

server ID 3324150:com.sap.engine.services.deploy.container.DeploymentException:
Why this exception is coming and how can i resolve this issue?

Hi,
the initial exception suggest
After an upgrade from SAP NetWeaver release 2004 to SAP NetWeaver release 7.0, according to the new SAP security policy, the J2EE Engine administrator user may be prompted to change his or her password. The password is changed in the User Management Engine (UME).
According to SAP security policy, the J2EE Engine administrator password must be changed every 90 days. The password is changed in the UME.
However, SDM reads the J2EE Engine administrator password not from the UME, but from the secure storage instead. The J2EE Engine administrator password is not changed in the secure storage. For more information, see SAP Note 870445.
and the possible Solution could  be
Change the J2EE Engine administrator password in the secure storage
