Re: Does jBoss work on iSeries?

[Ivan Hurtado <iva030@xxxxxxxxx>]

For this project I'm designing, it will ALL reside on
a single as400 machine. There are no other
servers/machines involved here. That is why I am
hesitant to jump into the EJB world for this. I want
something simple to produce and which performs fast.
If I avoid EJB, then I can disregard the need for
expensive Websphere Enterprise Servers and such,
simply using Tomcat as a standalone. Also I don't have
to deal with the EJB complexity. However, I was
looking for good alternatives since using EJB does
provide much system level functionality via the
container (i.e state mgmt, threading, transaction
control, pooling, persistence, etc.). 

I have looked at google searches for EJB. I know I can
use JDO, or even Record-Level I/O from jt400, to
access the database instead of using CMP. But I was
concerned about how much of that system level code I'd
have to write myself if I did not EJB at all.

To consolidate some of the responses, it sounds like I
can use something called Proxool to handle connection
pooling. And Hibernate (not familiar with it) to
handle persistence (not sure if this is instead of or
in addition to using JDO). Then that leaves state
mgmt, threading and transaction control to be dealt
with... any suggestions on how to best deal with those
items without EJB?

Thx!
