Tomcat JMX / RMI：如何选择服务器接口？

Question

I enable JMX server and JMX Registry in Tomcat using

<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"
      rmiRegistryPortPlatform="10001" rmiServerPortPlatform="10002" />

Client connects to 10001 and Tomcat returns its address and port 10002, right? But if I have several addresses on the interface Tomcat returns the first one.

• Is this a tomcat or RMI issue?
• How can I set interface and/or IP address to be returned to the client?
• Is it possible to use JMX directly over the one TCP port with out of all that RMI stuff?

Answer 1

For you question: you should specify -Djava.rmi.server.hostname=xxx.xxx.xxx.xxx as outlined in the answer Tomcat 6, JMX and the dynamic port problem

As an answer how to configure direct access: specify the JMX remote port as outlined in Monitoring and Managing Tomcat :

    set CATALINA_OPTS=-Dcom.sun.management.jmxremote
    -Dcom.sun.management.jmxremote.port=%my.jmx.port%
    -Dcom.sun.management.jmxremote.ssl=false 
    -Dcom.sun.management.jmxremote.authenticate=false

As far as understand, the calls are still done as RMI calls.
