Hi Bill,

Thanks for the info. I checked, but there isn't any xerces jar in $CATALINA_HOME/common/endorsed... only jaxp_parser_impl.jar and xml-commons-apis.jar. This was just a basic RPM install of Tomcat along with the admin webapps. Also, the exception trace I posted _was_ from catalina.out, so that's as detailed as it gets.

By the way, what is this MBean server it is looking for anyways?

Thanks,

I'm guessing that there is a more informative message in 'catalina.out', and
that the problem is that 4.1.12 doesn't work with xerces-2.2.x (other than
'nightly').  Replace the xerces jars in $CATALINA_HOME/common/endorsed with
the 2.1.0 version, and it should be fine.

I have the following packages installed on a RedHat 7.3 box:

   tomcat4-4.1.12-full.2jpp
   tomcat4-admin-webapps-4.1.12-full.2jpp

Tomcat starts up fine and I can log into the admin app without problem.
However, the moment I try to do anything in the admin app I get a "HTTP
Status 503 - Servlet action is currently unavailable" error, and I see
this in my catalina.out log file:

javax.servlet.UnavailableException: MBeanServer is not available

What does this exception mean, and what do I need to do to get the admin
app running?

Thanks,
