HowtogetAllClusterNodeDetailsusingJMXinJBossAS7.1.2

byAuthor_1underCluster,JbossAS7,JBossAS7,MBeans

Hi,

InJBossEAP5orAS6orpreviousreleasestherewasaconceptofPartitionNamewhichcouldbeusedtoget the listofactiveclustermembers,However inJBossAS7 there isnoconceptofPartitionNameratherinUDPmodethelusteringhappensbasedonthemulticastasddress(ClusteringcanbeachievedusingTCPmodeofcommunicationaswell).HowevermanydeveloperswanttolistthenumberofactivemembersrunningaspartofaJBossAs7clusterprogramatically.

So in this examplewewill see how towrite a simple JMXCode in order to access the cluster node
