It agree it is unfair in the current state of JOnAS, but our target is that it
becomes fair as soon as possible. We are working hard to improve JOnAS and
performances, and I apologize that we don't enough inform you on that. We will
try to inform you better on our work and plans. I just give initial answers here,
and we will give more infos soon. Don't hesitate also to ask us for more infos.
I know we don't take enough performances into account until now. We are now
working hard on that also.

We know that is the current critical point. the two main reasons are bad RMI
performances and lack of data caching:
- For RMI a JOnAS version using Jeremie instead of Sunsoft RMI is available, and
it is very promising (several hundreds times faster for local calls), but remote
calls still need improvments.
- For data caching we are developping a new version of container managed
persistence based on a new powerful Java object to relational data mapping
(called JORM). This will be the basis for a distributed cache management. We
expect to have this new version of container managed persistence in June.

We don't implement activation/passivation until now because we will do it only
for the new version of container managed persistence. We have to check the
dependencies, and if possible, do it sooner.

We will deliver XML support for deployment support in March.

There are a lot of improvments on that in version1.6.
If you have any problems or suggestions please give them to us.

We are working hard in order you will be able to do it soon.
We have now a very strong partnership with Lutris Technologies (see
www.lutris.com) to provide a high quality J2EE(TM) compliant open source server
called Enhydra Enterprise (see www.enhydra.org) by integrating Enhydra and JOnAS.
The first integrated version is planed for end of March, and a high quality
version end of June.

Please send also on the list and to us, all your feedback, and the results of
your evaluations, even (and mainly) negative ones. This will help to know the
priorities for improvements.
