[Daniel Rhoades]

statefull beans are tied to a client (until they are removed), stateless beans can talk to many different clients between method calls.

Therefore you don't need as many beans in the pool with stateless beans - saving resources.

[Praveena Jayanthi]

The stateless session beans are pooled on the server startup( reused after the EJB method calls end).

The stateful session beans are created on client demand and are destroyed after use.

[Scott Johnson]

A stateful session bean can keep data between client calls. This means resources (memory, db connection, etc.) are held by the bean waiting for another call from the client.

A stateless session bean does not keep data between client calls. All resources are released after each call and available to other users.
