Steps to Reproduce



Add a node to connect to a remote SMA ( JBOSS)

Root Cause



JBoss-EAP-6.1 no longer provides support for remotely connecting to their MBeanServer over the RMI protocol. Since v6.1 JBoss have implemented their proprietary remoting-jmx protocol to remotely connect to the managed MBeanServer (Management server) which mandates use of the following connection URL - service:jmx:remoting-jmx://{host_name}:{management.native.port}

Resolution



Any client java application trying to remotely access the JBoss MBeanServer via the remoting-jmx protocol will need to have the following client JAR in its CLASSPATH – jboss-client.jar


Next Steps –


1) Re-package the out-of-the-box 717 prsysmgmt.war file to budle the jboss-client.jar under the WEB-INF/lib directory of the prsysmgmt.war. The jboss-client.jar is usually located under the JBoss-EAP-6.1 server’s directory structure – (JBOSS_HOME/bin/client).

2) Stop / disable the deployed prsysmgmt application using the JBoss admin console. And then, remove the disabled prsysmgmt application using the JBoss admin console.

3) Re-deploy the re-packaged prsysmgmt.war from Step 1 above.

4) Configure the remote PRPC node by launching the prsysmgmt application in a browser window and use the URL - service:jmx:remoting-jmx://{host_name}:{management.native.port} to connect to remote PRPC JVM/node.
