Tim, Thanks a lot for your help. I have compared your code snippets with our actual files. Our deploy/jboss-messaging.sar/remoting-service.xml looks like this: | <mbean code="org.jboss.remoting.transport.Connector" | name="jboss.messaging:service=Connector,transport=socket" | display-name="Socket transport Connector"> | <attribute name="Configuration"> | <config> | <invoker transport="socket"> | <attribute name="marshaller" isParam="true">org.jboss.jms.server.remoting.JMSWireFormat</attribute> | <attribute name="unmarshaller" isParam="true">org.jboss.jms.server.remoting.JMSWireFormat</attribute> | <attribute name="serializationtype" isParam="true">jboss</attribute> | <attribute name="dataType" isParam="true">jms</attribute> | <attribute name="socket.check_connection" isParam="true">false</attribute> | <attribute name="timeout">0</attribute> | <attribute name="serverBindAddress">${jboss.bind.address}</attribute> | <attribute name="serverBindPort">4457</attribute> | <attribute name="leasePeriod">20000</attribute> | <attribute name="clientSocketClass" isParam="true">org.jboss.jms.client.remoting.ClientSocketWrapper</attribute> | <attribute name="serverSocketClass">org.jboss.jms.server.remoting.ServerSocketWrapper</attribute> | </invoker> | <handlers> | <handler subsystem="JMS">org.jboss.jms.server.remoting.JMSServerInvocationHandler</handler> | </handlers> | </config> | </attribute> | <depends>jboss.messaging:service=NetworkRegistry</depends> | </mbean> | It differs from your template in the serialization type (jboss vs. jms), the lease period, and the missing callbackStore definition. This file should be unchanged from the Messaging 1.0.1.SP2 installation. The code in our bindings xml file also reflects these differences (I suppose it has to match the definition from remoting-service.xml and not messaging-service.xml). There is one further difference: The serverBindPort value is already showing the new port number, not the original one as in your example. If I specify the original port, the mapping is not performed. <service-config name="jboss.messaging:service=Connector,transport=socket" | delegateClass="org.jboss.services.binding.AttributeMappingDelegate"> | <delegate-config> | <attribute name="Configuration"><![CDATA[ | <config> | <invoker transport="socket"> | <attribute name="marshaller" isParam="true">org.jboss.jms.server.remoting.JMSWireFormat</attribute> | <attribute name="unmarshaller" isParam="true">org.jboss.jms.server.remoting.JMSWireFormat</attribute> | <attribute name="serializationtype" isParam="true">jboss</attribute> | <attribute name="dataType" isParam="true">jms</attribute> | <attribute name="socket.check_connection" isParam="true">false</attribute> | <attribute name="timeout">0</attribute> | <attribute name="serverBindAddress">${jboss.bind.address}</attribute> | <attribute name="serverBindPort">11107</attribute> | <attribute name="leasePeriod">20000</attribute> | <attribute name="clientSocketClass" isParam="true">org.jboss.jms.client.remoting.ClientSocketWrapper</attribute> | <attribute name="serverSocketClass">org.jboss.jms.server.remoting.ServerSocketWrapper</attribute> | </invoker> | <handlers> | <handler subsystem="JMS">org.jboss.jms.server.remoting.JMSServerInvocationHandler</handler> | </handlers> | </config> | ]]> | </attribute> | </delegate-config> | | <binding port="11107" /> | </service-config> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4000959#...
