Hi James,
thanks for your helpfull respone.

Okay. In something JMXish like JBoss wouldn't be a MBean a nice choice for
configuration? Actually I like the JMX aproach a lot. It's a shame
that only a few Appsever's support this great technology....

In EJB this would be a much greater Problem. So the only thing i guess is to
insert
the complete xml string into a ejb-env entry or access it via JNDI.
Mhm. But this means that MessengerManager may need a configure(Document
document)
method processing a based dom4j document. Again here I would love it load
the configuration
from a MBean. So I guess I spent some investigations in that. What do you
think?
BTW: I know you a critic of EJB's. After writing an application using CMP
2.0 Entity Beans
and a couple of MDB I follow most of your points. What do you think in this
context about
MDB? Usefull or painfull? Actually I'm a big fan of JMS, because it offer so
much flexibility.

Thx for that hint.

Cooool. Thanks for providing such usefull tools.
Bye
