Hi , I try to get partition(cluster) name using external applicatin using JMX. String jmxQuery = "jboss:service=DistributedReplicantManager,*"; // getting the server MBean Set set = connection.queryNames(new ObjectName(jmxQuery), null); if (set != null && set.size() > 0) { // this is a cluster for (Iterator i = set.iterator(); i.hasNext();) { ObjectName on = (ObjectName) i.next(); System.out.println("--"+on); String ClusterName = on.getKeyProperty("partitionName"); } } Is it correct way to get a cluster name using DistributedReplicantManager. and may be you have a reference how to discover a full topology of jboss (all partitions , clusters and servers in it).
