    server invocation handler and JMX

    mazz Master

      So, this stuff looks really cool. I was in the middle of writing a server class to mimic SimpleServer when I realized that that is what that remoting-service.xml deploys for you! So, running inside of JBoss with remoting-service deployed gives me that for free.

      All I need to do is write my ServerInvocationHandlers right? With the config defining my locator URI, all I have to do it plugin my handlers with their respective . So, really I just have to worry about writing the business logic in my invocation handlers and the registering with the network manager, marshalling/unmarshalling, etc. is taking care for me. Nice.

      Question - can I write my handlers as MBeans themselves? This would allow local invocation through JMX API? Not sure how that would get configured - since just takes a class name.


      I deploy my own handler services that depend on the remoting service. The remoting service should be told that I am giving it a JMX name - e.g. jboss:name=MyInvoker

      Not sure where the upcoming JMX invocation handler fits it - would it just remote my JMX interface to that service? In that case I don't even write to the invocation handler interface; I just write MBeans and the JMX subsystem invocation handler will remote my JMX interface to my service?

      Sorry for the slew of questions - its starting to click for me, but I'm not grasping it the whole way yet...

          No way to make the handler an MBean at the moment. Would not count on the JMX invocation handler for a while (as will be when I get to JSR 160, which is a ways out).

          It wouldn't be that difficult to call on the handlers via JMX and just specify the object name. What's the use case for this (not that I think it is a bad idea, just curious). If this is something you really want to see added, please create an issue for this in jira.jboss.com.

            No current requirements, I just thought it would be cool :-) Actually, I'm thinking make it an MBean to allow for inproc calls more efficient (if I have an client inproc with the MBeanServer, would be better to make a local JMX API call as opposed to going through the remote layer and incur the penalty of (un)marshalling)?

              Is a good idea to have it, so will create a jira issue. BTW, remoting will do in process calls automatically if sees that the server and client remoting invoker live in the same jvm.
