JBOSS JMS clustering

=============================================================
JBoss Messaging clusters JMS queues and topics transparently  across the cluster. Messages sent to
a distributed queue or topic on one node are consumable on other nodes. To designate that a particular destination is clustered, simply set the Clustered attribute in the destination deployment descriptor to true:

=============================================================
<mbean code="org.jboss.jms.server.destination.QueueService"
name="jboss.messaging.destination:service=Queue,name=clusteredQueue"
xmbean-dd="xmdesc/Queue-xmbean.xml">
<depends optional-attribute-name="ServerPeer">
jboss.messaging:service=ServerPeer
</depends>
<depends>jboss.messaging:service=PostOffice</depends>
<attribute name="Clustered">true</attribute>
</mbean>
