Ivan,

I would stick with simple unless you are adding a new feature to an
existing EJB-based application. The simplest pooling I have used is
Proxool, which took about 1 hour to implement. Tomcat or another servlet
container should handle most threading and session needs but you should
become familiar with servlet filters, which can be very helpful in
setting up your session. I have had good luck with Hibernate and it
scales well. A bonus is that I can develop my applications stand-alone
on my PC with something like MySql. A drawback is that in some cases
(like heavy duty reporting) a persistence layer will add too much
overhead.

Joe,

I am in the infancy stage with this design, so I can
go in any direction. Using EJB is the major decision I
am still grapling with. I understand what you are
saying about using JDO for data access, however, what
about all the other system level functionality that an
EJB server/container provides... i.e. the connection
pooling, thread mgmt, session/state mgmt, etc? I'd
rather not code any of that.
