I've experienced the same thing on NT. The "workaround", which isn't a
workaround, is that by uninstalling and then re-installing and re-running
everything works fine. The problem is encountered when you shut it down
once and then try to restart it.
It seems to be choking on the getConnection which requires both a user id
and password in the XAConnectionFactory object.
Sorry I couldn't be of further assistance.

Subject: [jBoss-User] Linux "url cannot be null" exception
All,
I'm running a fresh install of Caldera Linux 2.4. I installed the jdk1.3,
j2ee1.2.2 and then jboss. I started jboss and it deployed both test apps and
one of my one apps fine. Later, I stopped jboss and restarted it only to
receive the following error. Any ideas?
Thanks,
-john
