How to configure Message bridge

Question

          Hi,
          I am trying to setup a JMS Message Bridge for prove of concept purpose in Weblogic
          7.0. Here is my configurations from config.xml:
          <JMSBridgeDestination
          AdapterJNDIName="eis.jms.WLSConnectionFactoryJNDIXA"
          ConnectionFactoryJNDIName="weblogic.jms.testConnectionFactory"
          ConnectionURL="t3://localhost:7001"
          DestinationJNDIName="examples.queue2" Name="LocalBridge"
          UserName="kyang" UserPassword="{3DES}2LeceOSYOaRuCvrFshnBZg=="/>
          ConnectionFactoryJNDIName="weblogic.jms.ClientConnectionFactory"
          ConnectionURL="t3://localhost:7001"
          DestinationJNDIName="examples.queue1"
          Name="MQWeblogicDestination" UserName="kyang"/>
          <JMSConnectionFactory DefaultDeliveryMode="Persistent"
          DefaultTimeToDeliver="200" DefaultTimeToLive="1000"
          JNDIName="weblogic.jms.ClientConnectionFactory"
          LoadBalancingEnabled="false" MessagesMaximum="100"
          Name="ClientConnectionFactory" OverrunPolicy="KeepNew"
          ServerAffinityEnabled="false" Targets="examplesServer"/>
          <JMSConnectionFactory DefaultDeliveryMode="Non-Persistent"
          DefaultTimeToDeliver="200" DefaultTimeToLive="1000"
          FlowControlEnabled="false"
          JNDIName="weblogic.jms.testConnectionFactory"
          Name="testConnectionFactory" OverrunPolicy="KeepNew" Targets="examplesServer"/>
          <MessagingBridge Name="MyMessaging Bridge" Selector="*"
          SourceDestination="LocalBridge"
          TargetDestination="MQWeblogicDestination" Targets="examplesServer"/>
          I used a test client get InitialContext with url:"t3://localhost:7001" and send
          the message to "examples.queue2" which is "MyJMSQueue".
          From the monitor screen I found the message was put on "MyJMSQueue" but the message
          was nerver delieveried to the "examples.queue1".
          From the log, I got following message:
          <Jun 20, 2002 10:05:53 AM CDT> <Info> <MessagingBridge> <200012> <Bridge "MyMess
          aging Bridge" suceesfully found the two adapters configured for it.>
          Do you have any suggestions?
          Thanks a lot!
          

Answer 1

Don't worry about the log messages about
          "comp/env/wls-connector-resref".
          It is not a problem for the Messaging Bridge feature.
          The real problem is that you have an invalid selector for the
          MessagingBridge. A bridge selector has the same syntax as a JMS message
          selector. As you can see from the JMS specification, a message selector
          syntax is based on a subset of the SQL92 conditional expression syntax.
          I would suggest you try the bridge feature without any selection first
          and add the selector later.
