Just as a follow up...
What I have noticed, and it is consistent on both NT and Linux (Red Hat 6.2
at least) is that the error can be repeated if the shutdown of the server,
for whatever reason, is not successful.
There have been instances when I have not had the Server shutdown properly
when issuing either the "kill" Unix command, or CTRL-C in NT. The next time
I attempt to start up JBoss is when I encounter the error.
Therefore, from what I can tell is that, the file "jboss.jcml" is corrupted
on an unclean exit.
For what that worth.
Take care.

All you truly need to to is replace the "jboss.jcml" file with the
original one, or with a working one. The file gets rewritten by the
server, and for some reason it occasionally leaves out the URL field. We
need to figure out what causes that - I haven't been able to duplicate
it. Were there any database errors when you started it the time before it
broke?
