It would help to know the Tomcat version you are using.  e.g.
Tomcat-5-nightly seems to break the admin app a lot (but it is Alpha at
best, so it's the price of living on the bleeding edge :).

Otherwise, I'm guessing that you are building from src, and neglected to
include the JMX jars in the file.

I apologise in advance if this question has been asked and answered, but in
 my defense, I have searched the archives and found nothing appropriate.

Everytime I try to run the admin app (log in and get the main page, select
option), I get a "javax.servlet.UnavailableException: MBeanServer is not
available" error in the admin apps log file.

The two required listeners (I believe) are in the server.xml file:

  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener"


Any suggestions would be greatly appreciated,
