What is the policy for Work Load Management and stateful session beans?
The behavior of stateful session beans in 4.0 will be the same as the behavior in WebSphere 3.x. Stateful session beans can be modeled and cloned. However, you will not get the workload management of these beans. This is due to the fact that a stateful session bean is associated with a specific client. In most cases, Work Load Management of these EJBs actually results in worse performance, rather than better, as you significantly increase the amount of cross-process, and possibly cross-machine calls required.
