Hi Poyan, The Remoting bisocket transport used by JBossMessaging has a second ServerSocket on the server which has to be accessible. Bisocket was designed for the use case in which the client was behind a firewall but the server was not, and the second ServerSocket used a random port. Since Remoting version 2.2.2.GA, the second port has been configurable: see JIRA issue JBREM-749 "BisocketServerInvoker: Make configurable the address and port of secondary server socket" (http://jira.jboss.com/jira/browse/JBREM-749. The remoting jar (jboss-remoting.jar) for version 2.2.2.GA (or later - the most current release is 2.2.2.SP2) is available from http://repository.jboss.com/jboss/remoting/. You need to put the jar in the lib directory of your particular server configuration: e.g., $JBOSS_HOME/server/messaging/lib. Also, you need to configure the secondary port in server/messaging/deploy/jboss-messaging.sar/remoting-bisocket-service.xml. For example, to set the secondary port to 5445, add the secondaryBindPort attribute as follows: | <mbean code="org.jboss.remoting.transport.Connector" | name="jboss.messaging:service=Connector,transport=bisocket" | display-name="Bisocket Transport Connector"> | <attribute name="Configuration"> | <config> | <invoker transport="bisocket"> | <attribute name="marshaller" isParam="true">org.jboss.jms.wireformat.JMSWireFormat</attribute> | <attribute name="unmarshaller" isParam="true">org.jboss.jms.wireformat.JMSWireFormat</attribute> | <attribute name="dataType" isParam="true">jms</attribute> | <attribute name="socket.check_connection" isParam="true">false</attribute> | <attribute name="timeout" isParam="true">0</attribute> | <attribute name="serverBindAddress">${jboss.bind.address}</attribute> | <attribute name="serverBindPort">4457</attribute> | <attribute name="leasePeriod">10000</attribute> | <attribute name="clientSocketClass" isParam="true">org.jboss.jms.client.remoting.ClientSocketWrapper</attribute> | <attribute name="serverSocketClass" isParam="true">org.jboss.jms.server.remoting.ServerSocketWrapper</attribute> | <attribute name="numberOfRetries" isParam="true">1</attribute> | <attribute name="numberOfCallRetries" isParam="true">1</attribute> | <attribute name="clientMaxPoolSize" isParam="true">50</attribute> | <attribute name="secondaryBindPort">5445</attribute> | </invoker> | <handlers> | <handler subsystem="JMS">org.jboss.jms.server.remoting.JMSServerInvocationHandler</handler> | </handlers> | </config> | </attribute> | </mbean> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4093766#...
