Thank you Aaron, that worked quite well!
My next newbie step was to integrate with Tomcat. That's gone
fairly smoothly, but now that I'm attempting to look up objects
in Tomcat that I bound to the JNDI tree in my custom service, and I'm
running
into classpath problems. This is most certainly happening because
to cast I'm trying to cast a class that was loaded by jBoss to
a class that was loaded by Tomcat. I've seen other people dealing
with this in the mail list, but I can't seem to reproduce their
solution.
One thing I don't understand is how to use the Jdk12Interceptor.
Many of the people on the mailing list mention it as solving the problem.
It seems that it is crucial, but the documentation seems to
contradict itself regarding server.xml, where it is set up. The
Tomcat HOWTO (http://www.jboss.org/tomcat.htm) makes no mention
of Jdk12Interceptor, and even explicitly states that Tomcat's server.xml
will not be processed. However in the Tomcat section of the Getting
Started guide (http://www.jboss.org/manual/third_party.html#tomcat),
it mentions adding the RequestInterceptor tag to the server.xml
file. I tried adding this tag, despite the HOWTO's warnings
that server.xml would not be parsed, but to no avail. Which
guide for setting up Tomcat is correct here?
In general, are there more explicit rules for setting up classpath with
regards to Tomcat/jBoss? I have my proprietary classes in a jar
named working.jar. I believe they should go into at least jboss/lib/ext.
Should it go into the WEB-INF/lib directory as well? Should it be
explicitly added to the CLASSPATH in run.sh?
I'm running this on Sun 1.2.2/Redhat Linux/Tomcat 3.2 beta 4/jBoss beta 3
(downloaded Tuesday).
Thank you for any help.

Try making your TestServerMBean extend
org.jboss.util.ServiceMBean. The start method is declared in a parent
interface to ServiceMBean, and JMX needs the "start" to be declared in an
interface before it can be called on an implementation. FYI, the
"Start" in ServiceMBeanSupport calls your "startService".
