Subject RE: Jmxproxy issue
Date Fri, 14 May 2010 11:49:45 GMT

Thanks again for responding, both the servers have exactly similar following configuration,
and I am able to execute /jmxproxy/?qry=java.lang:type=OperatingSystem query successfully
on one (i.e. getting the output) and for the other server the search string returns OK - Number
of results: 0

Apache Tomcat/5.5.9
OS Version - 2.6.9-67.ELsmp 

I have also checked server.xml files and they are exactly similar.
Any pointers on which configuration to look for.

does work in pristine installation built from the current 6.0.x
sources as of now, but does not in the current 5.5.x,
both running with Sun JDK 6u20.

I think it might be related to the following changelog entry of Tomcat
6 (in version 6.0.21):
"Tomcat now uses the Platform MBean server by default" (...)

"6.0.21" means that it is included in 6.0.24 and later releases. The
above was not
backported to 5.5 branch.

Maybe there is some configuration that will allow seeing the above in
5.5, but I doubt that there is. Also check, what JRE versions your
servers are using.

In any case, as Pid already said, you should consider upgrading.
