Hi Andy,
I am connected with the Enhydra project, but do have a couple
of points of information. Rickard is correct about the current
(released) state of JOnAS, however, JOnAS has joined forces with
the Enhydra project to create Enhydra Enterprise. This is a
completely different animal: first of all the architecture is
based around a small, high quality, "kernel" called the
multiserver. This server provides an interface for managed
services (EMS). Each service can be used independently. JOnAS is
being split into 3 EMS services: transaction, EJB container and
database manager. This is in addition to the webcontainer,
naming, messaging, management, logging, etc, provided by the
Enhydra team. Each of these services provides a JMX MBean for
management. The idea is that the services will be replaceable so
that is the JOnAS EJB container is not suitable you could add in
a suitably modified eBoss EJB container after all, eBoss does use
the JOnAS transaction manager code.
If you are interested in what we are doing then check out
http://www.enhydra.org. The code is currently in alpha witha
large drop expected within a couple of weeks.
BTW the above is meant to be information only. I have a lot
of respect for the work of Rickard and the eBoss project, but
wanted to fill in a little information about the direction of
JOnAS.

Compared to JOnAS we have a much cleaner architecture which
allows a lot
more flexibility. Adding custom functionality is done through the
plugin
infrastructure of jBoss, which is very nice to have. On the user
point
of view, our easy-to-use hot-deploy features are very nice to
have, and
I don't know if anyone (even commercial) does it this easily.
With respect to OpenEJB, the little I have seen of it seems to be
along
the same lines as jBoss (which is natural considering that RMH
who is
the developer lead was on EJBoss awhile ago), but IMHO jBoss 2.0
is way
ahead in terms of the maturity of the architecture.
With regard to both of these other project I think you will find
that
jBoss is very easy to use, and (above all?) has a very strong
community
tied to it, which is important in a OpenSource context. Having
lots of
people using it will of course increase the level of testing,
suggestions for new cool features, and provide good discussions
around
server development. Also, since jBoss i JMX based it is very easy
to add
custom functionality to it. The EJB container itself is merely a
JMX-component just as anything else that you might want to add.
IMHO
this is a very powerful and useful feature.
Etc. etc. :-)
