May 28, 2002 · If you keep a connection in a stateful session bean, the connection is tied to a single client, limiting your application's scalability. You can then implement a stateful session bean that invokes your facade bean. Will this work for your situation?

Dec 16, 2003 · Stateful session beans are dedicated to one client for their entire life, so there is no swapping or pooling of instances. Instead of pooling instances, stateful session beans are simply evicted from memory to conserve resources.

Stateful session beans are not normally pooled. It's possible, but their state makes them less ideal to pool as the client expects a fresh bean when obtaining a reference. For stateless beans, yes the 51st client will have to wait.

Stateful session beans are useful for conversational sessions, in which it is necessary to maintain state, such as instance variable values or transactional state, between method invocations. These session beans are mapped to a single client for the life of that client.

When a method completes, state information is not retained. Any instance of a stateless session bean can serve any client—any instance is equivalent. Stateless session beans can provide better performance than stateful session beans, because each stateless session bean instance can support multiple clients, albeit one at a time.

Stateful Sessions Beans Are pooled in memory, to save the overhead of creating a bean every time one is needed. WebLogic Server uses a bean instance when needed and puts it back in the pool when the work is complete. Stateless sessions beans provide faster performance than stateful beans.

In a stateful session bean, the instance variables represent the state of a unique client/bean session. Because the client interacts (“talks”) with its bean, this state is often called the conversational state. As its name suggests, a session bean is similar to an interactive session.
