Serialize stateful session bean to xml

Question

Hi,
Here is the scenario:
1. Stateful session bean is created.
2. XML message is sent to the queue. The xml message needs to have a reference to the session bean created in the first step.
3. MDB.onMessage reads the xml and invokes a method on the stateful bean
What are the different approaches to implement the second step? That is to create a reference to an instance of the session bean and at runtime invoke the same instance.
Thank you

Hi,
I don't know if it works with a serialization to xml, but for (for example) a web application you would probably put the handle to the statefull session bean in the session. If I am not wrong, the implementation of handle object should be serializable (http://java.sun.com/products/ejb/javadoc-1.0/javax.ejb-javadoc/javax.ejb.Handle.html)
Please post a reply if it worked, because the problem is interesting
Georges
Handle h = (Handle) session.getAttribute("myStateful");
MyStateful statefulBean = null;
if ( h == null) {
statefulBean = createStatefulEJB();
if (statefulBean != null) {
h = statefulBean.getHandle();
session.setAttribute("myStateful", h);
} else {
statefulBean = (MyStateful) PortableRemoteObject.narrow (h.getEJBObject() , MyStateful.class);
