Hi

I'm one of developers of OpenJMX. We will be developing in OpenJMX an admin 
app for JMX applications inside web containers. I wonder whether Tomcat will 
be doing exactly the same (A general JMX admin app) or a specific admin tool 
for Tomcat only.

Anyway I'd be interested to collaborate specially if it can benefit both 
OpenJMX and Tomcat
