As in EJBHF, when a client use an EB, 3 types of scenario occus, the client can create or find an existing entity, or get an EB sub component from Home business method. In these 3 types, only when a client create an entity would require a bean to be brought out of the pool to server the client. But what is the difference that the bean do some work in the pool or outside of pool? Since they all exist on live heap.
Besides these, only SFSB passivation will place the bean really out of heap (hope I'm right), for the rest of cases, what are the really difference the beans, either SB, EB, or MDB, are in the pool or outside of the pool?
Thanks.
