Hi Robert

I got the solution: you have to take the original jmx 1.2 RI version from
SUN instead of that jmx which comes with tomcat (see also
http://issues.apache.org/bugzilla/show_bug.cgi?id=29671)

- Download from http://java.sun.com/products/JavaManagement/download.html
the "JMX 1.2 Reference Implementation"
- Unzip lib/jmxri.jar from this file
- Copy jmxri.jar to $TOMCAT_HOME/bin/jmx.jar
- delete $TOMCAT_HOME/work/*
- restart Tomcat

I have tomcat 5.0.27 and it works perfectly!

Have a nice day and a good time
Didi

Other than to restart the server and cross my fingers, no I haven't found a
solution.  Perhaps it should be submitted as a bug.

Hello Robert
