Phillippe,
I think that in general the strategy of instantiating stateless session bean
instances when needed is perfectly suitable. The reason i would like to be
able to pre-instantitate them is that my beans take a long time to construct,
but only a short time on each business method call ... so obviously i want the
response time on the business method calls to be short and having to construct
one for each call would prevent that from happening.
I am using a stateless session bean rather than a stateful one because i don't
want to be able to pool them rather than having one per user (they use quite
a lot of memory too). A stateless session bean seemed like a good way to
implement the pool so that the container could deal with the pooling mechanics,
but lack of administrative control over the pooling behaviour is a problem.
For large construction-time stateless session beans, i think it would be useful
to be able to have some administrative control over the pool size to avoid
unnecessary construction and consequent slow response time.
