Rickard,
sorry for not responding with my gratitude sooner. I created an MBean by
using the org.jboss.util.Info (MBean) as an example and registered my RMI
object with the jboss JNDI tree in preRegister() and also stored a reference
to the RMI object in a data member to prevent GC. I looked in the
jboss/conf/jboss.conf file to get an MLET tag example and created the
appropriate MLET tag for my MBean. I cranked up jboss and everything worked
as you said it would. The MBean preRegister() method was called and my RMI
object was registered with the JNDI tree.
Thanks again!

Exactly.

You guessed right.

Yup, that is the idea. You can copy an existing MBean in jBoss and go
from there. You can, for example, copy the org.jboss.util.Info(MBean)
classes and modify so that it creates your RMI object instead. Then add
it to jboss.conf (see how Info is added for example) and off you go :-)
