Stateful Session Bean

[Ashok Jaganathan]

Can I say a session scope in JSP bean as Stateful session bean?

[Lasse Koskela]

Come again? If you're asking whether a JavaBean stored into HttpSession with session scope is a stateful session bean, the answer is no. If you're asking whether you can store a reference to a stateful session bean into HttpSession with session scope, the answer is yes but only by breaking the rules. The reference isn't serializable, which is required by the spec for all objects put into HttpSession but in practice you can get away with unserializable objects in HttpSession as long as you don't have a cluster (i.e. the container doesn't attempt to serialize the objects).

If you are just comparing the way these two work , Yes.
Both have an identifier and maintain the session state with the calling client. Obviously, the purpose and the mechanism are very diff.

Thanks Lasse and Rangarajan for your replies.Rangarajan can you briefly tell me in what way the purpose and mechanism are different.
