Dear all,
I faced a problem enabling JmxRemoteLifecycleListener with
useLocalPorts="true" : my hyperic agent fails to connect with an
UnmarshalException caused by a ClassNotFoundException on
JmxRemoteLifecycleListener$RmiClientLocalhostSocketFactory (details below).
The workaround I found is to copy catalina-jmx-remote.jar under
$HYPERIC_AGENT_HOME/bundles/agent-4.1.2-1053/lib/ .
However, for a long term fix, I would find interesting to have
useLocalPorts="true" working out-of-the-box with tools like Hyperic HQ.
Surprisingly, this problem occurs with hyperic agent but not with VisualVM ;
I didn't have the time to investigate?
I don't know yet if the long term fix is on hyperic-agent or tomcat side.
I just wanted to share the issue and the workaround with the community as I
didn't find anything on Google.
If someone has insights on this problem, I am very interested.
Cyrille
