Steps to Reproduce



Configure a node from SMA. Unable to add the node.


Root Cause



Native management interface was introduced in JBoss 6. This interface used the JBoss Remoting protocol instead of the Remote Method Invocation (RMI). Consequently, Java Management Extensions (JMX) connection through RMI was not enabled by default.


Resolution



Perform the following local-change:
  1. Include <module name="org.jboss.remoting-jmx" slot="main"/> in the below element to modify the standalone-full.xml.

    <subsystem xmlns="urn:jboss:domain:ee:1.2">
        <global-modules>
            <module name="com.oracle"/>
            <module name="org.jboss.remoting-jmx" slot="main"/>
        </global-modules>
        <spec-descriptor-property-replacement>false</spec-descriptor-property-replacement>
        <jboss-descriptor-property-replacement>true</jboss-descriptor-property-replacement>
        <annotation-property-replacement>false</annotation-property-replacement>
    </subsystem>

     
  2. In Remote Connection, set the Server URL to server:jmx:remoting-jmx://aaa.bbb.c.dddd:9999

For the remoting port, default value is 9999. Verify this from the JBoss's server.log:

14:21:55,783 INFO  [org.jboss.as.remoting] (MSC service thread 1-2) JBAS017100: Listening on localhost:9999
