[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Why are the destinations looked up twice? (jbm1.4)

[gaohoward]

In Bridge.java, this code sets up the bridge stuff, at the beginning and after setting the QoS, the same source and target dests are looked up twice, any reason?

   private boolean setupJMSObjects()
   {
      try
      {  
      	//Lookup the destinations
      	sourceDestination = sourceDestinationFactory.createDestination();
      	
      	targetDestination = targetDestinationFactory.createDestination();
      	      
         if (sourceCff == targetCff)
         {
            //Source and target destinations are on the server - we can get once and only once
            //just using a local transacted session
         	//everything becomes once and only once
         	
         	forwardMode = FORWARD_MODE_LOCALTX;
         }
         else
         {
         	//Different servers
         	if (qualityOfServiceMode == QOS_ONCE_AND_ONLY_ONCE)
         	{
         		//Use XA
         		
         		forwardMode = FORWARD_MODE_XA;
         	}
         	else
         	{
         		forwardMode = FORWARD_MODE_NONTX;
         	}
         }
         
      	//Lookup the destinations
      	sourceDestination = sourceDestinationFactory.createDestination();
      	
      	targetDestination = targetDestinationFactory.createDestination();      	      
         
         sourceConn = createConnection(sourceUsername, sourcePassword, sourceCff);
