am going through enterprise session bean material.i have doubts regarding below oints :-

1) lets say we mentioned the pool size as 50 for some statful session bean. Different 50 clients use them .
so now all the 50 beans maintain some state. At what point of time will these states be removed so that
if 51th clien ask for bean it does not get any previous spoilt state.?

2) lets say we mentioned the pool size as 50 for some stateless session bean and all are in use at some
point of time. If 51th client comes and ask for a bean, will that wait till some bean become free
or create new bean instance?

    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. This is normally a good thing since it automatically moderates the resource consumption of your system. Depending on the resources you have, your workload and the amount of work being to in a single call to a ssb, you might want to tune the size of your pool.
