Title: SFSB Question

Stateless session beans imply that they cannot hold a state that is of any meaning to the client.  Thus it does not make sense for the client to try to pass in any kind of initialization parameter.  If you want to pass extra information into the session, that should be done via ejb-jar.xml descriptor in the session's environment.  If you describe why you need to do this, perhaps a better solution could be found.

 

State full sessions beans are expensive, and cannot be cached or re-used by the container.

On the project I'm working on, we've got a situation where it would extremely valuable to be able to have parameterized ejbCreate() methods on our stateless session beans, but the spec doesn't allow for this (we could put them in, but they'd never get invoked). 

One alternative would be to use stateful session beans, which allow this type of functionality.  The client would still be using the session bean in a stateless manner, however, e.g. one method call and it's done.  Is anyone aware of the potential overhead implications of making all of the session beans stateful versus stateless?  If it matters, the beans would be deployed under WL 6.1.

The other alternative that we're currently heading down is to take the parameter we'd like to pass in to ejbCreate() and add it to all of the business methods defined in the remote/local interface. 

Thoughts?
