Does Stateful Session bean support instance pooling?
According to Ed Roman, it does support pooling.
Can anybody pls tell me what specification says ?
Personally, I think that Richard is right, even after taking another quick look at the specs and thinking a little bit about it.
Reading the specs, in fact, there is no clear indication that a Stateful Session Bean is or is not pooled, while for the Stateless Session bean there is a specific paragraph (7.9.4 "Adding instance to the pool") that discuss the sequence for adding/removing an instance to/from the pool.
But, at the same time, I would accept that, maybe for gaining performance (or for other reasons), some containers do pool Stateful Session Beans just to avoid the overhead of recreating the object.
