Summary: tomcat uses wrong MBeanserver for Host mbean
Initial Comment:
When using java5 and -Dcom.sun.management.jmxremote to
setup the jmx monitor, the top level mbeans created by
tomcat use the default MBeanServer which is not that of
the tomcat service and the web app means cannot find
their host mbean:

The problem is that the engine is finding the mbean
server using the modeller Registry which is using
MBeanServerFactory.findMBeanServer(null).get(0):
public synchronized MBeanServer getMBeanServer() {
long t1=System.currentTimeMillis();
if (server == null) {
if(
MBeanServerFactory.findMBeanServer(null).size() > 0 ) {
server=(MBeanServer)MBeanServerFactory.findMBeanServer(null).get(0);
if( log.isDebugEnabled() ) {
log.debug("Using existing
MBeanServer " + (System.currentTimeMillis() - t1 ));
}
} else {
server=MBeanServerFactory.createMBeanServer();
if( log.isDebugEnabled() ) {
log.debug("Creating MBeanServer"+
(System.currentTimeMillis() - t1 ));
}
}
}
return (server);
}
The MBeanServer needs to be that of the tomcat service
or tomcat deployer.
