OC4J and Handle.getEJBObject()

Question

Hi all,
I am developing a Stateless session bean. I want to save its remote reference through a client so that I can call it later. The code is working fine in Websphere 6.0 but not in OC4J 10.1.3.
The Client Code is:
Hashtable env = new Hashtable();
//Setting properties
env.put(Context.INITIAL_CONTEXT_FACTORY, ctxFactory);
env.put(Context.SECURITY_PRINCIPAL, security_principal);
env.put(Context.SECURITY_CREDENTIALS, security_credentials);
env.put(Context.PROVIDER_URL, serverURL);
env.put(("dedicated.rmicontext","true");
public void callEJB(boolean startWhile)
InitialContext ic = new InitialContext (env);
//Looking up Home Object
SEJBRemoteHome homeObj =
(SEJBRemoteHome)PortableRemoteObject.narrow (ic.lookup (SEJB_Bean),SEJBRemoteHome.class);
SEJBRemote remObj = homeObj.create ();
Handle EjbObjHandle = null;
EJBObject eObj = null;
if(startWhile)
EjbObjHandle = remObj.getHandle();
//Saving Ejb handle
saveEjbObjHandle(EjbObjHandle);
//Calling EJB method
remObj.setPollProperty(startWhile);
else
//Getting Handle
EjbObjHandle = getEjbObjHandle();
EJBObject ejbObjRef = null;
ejbObjRef = EjbObjHandle.getEJBObject();
remObj = (SEJBRemote)PortableRemoteObject.narrow
(ejbObjRef,SEJBRemote.class);
remObj.setPollProperty(startWhile);
ejbObjRef.remove();
}//methos to save Handle
public void saveEjbObjHandle(Handle o)
try {
ObjectOutputStream objOut = new ObjectOutputStream(new
FileOutputStream(EJBObjPath ));
objOut.writeObject(o);
objOut.close();
catch (Exception e)
e.printStackTrace();
//method to Get handle
public Handle getEjbObjHandle ( )
Handle pHandleIn=null;
try {
ObjectInputStream objIn = new ObjectInputStream(new
FileInputStream(EJBObjPath));
pHandleIn = (Handle)objIn.readObject( );
objIn.close();
catch (Exception e)
e.printStackTrace();
return pHandleIn;
Error Msg:

I am getting this error while I am trying to executing else part. For if part it is initiating ejb and calling successfully the ejb method.
Can anyone explain this to me....and solve my problem. Am I violating any rule of OC4J or J2EE. I am trying to solve this error for past 3 weeks.....but unable to solve.
Any help will be appriciated.
Thanks....
