Problems with bridge between 2 weblogic

Question

Hello!
          We try to set up a bridge between 2 weblogic 8.0 on 2 machines to send JMS-messages.
          Our set up / system looks like:
          http://www.dsv.su.se/~fr-ander/images/Overview.jpg
          When we send our messages they do not seems to get all the way trough.
          Look at the following image that describes machine A during a send and receive.
          http://www.dsv.su.se/~fr-ander/images/weblogic_tables.JPG
          1 The bridge is running
          2 We have not send a message yet and the monotoring looks like this.
          3 We send a message from machine A to B.
          4 Very often, just after the message is sent, we get this message from the monotoring of the bridge:
          "WARN: faild and will connect later"
          It lokks like the bridge is connected again after 15-30 sec.
          How ever it seems that machine B indicates that something happens. In the next step (5) we have done the opposite and send from B to A. We get the same result on both machines when we monotor them after a send. In step 5 you see the monotoring of machine A after a send from B. The only difference is tha the bridge from B to A seems to be more stable and do not break down. It looks like it have the same state all the time "Forwarding messages".
          5 Assume that we have send a message from B to A then it seems that we get a indication about that at A ("Messages high" and Messages received" increase), something do get to the destination. (The same happens if the secnario is from A to B). But we do not get a indication in the "Messages" column!! When we try to read from the queue FredrikReceive or OscarReceive we get nothing.
          Do you guys got any idea why this happens?
          A) Why is the bridge "falling down" all the time when we send and why the bridge "get up" again a while later.
          B) Why do we do not find the real message, why do we get the indication that something happens but we can not read the message???
          Best regards
          Fredrik and Oscar

Hi Fredrik.
          Message bridges are tricky things, and there are a number of requirements that need to be in place for them to work correctly:
          - <b>ALL</b> JMS objects need to be unique between domains for XA transactions to work correctly. From looking at your diagram, this appears to be the case, but I can't see the name of higher level objects like your connection factory and JMS server.
          - the domains must have trust enabled, which means setting the same domain security credential for both domains
          - the correct adapter rar file needs to be deployed for the domain.
          Soooo...
          - which adapter are you using for the JMS bridge? (what is the name of the RAR file?)
          - are you getting any warnings/errors as part of starting the message bridge? From looking at the administration console, everything looks OK on first flush because you're getting a consumer plugged in.
          But if you're not seeing those bytes pending disappear, that means there are transaction issues in communicating between the domains. (most likely caused by domain trust)
          Try enabling the following switches in your start script for both domains:
          -Dweblogic.Debug.DebugMessagingBridgeStartup=true
          -Dweblogic.Debug.DebugMessagingBridgeRuntime=true
          There's a pretty good FAQ for troubleshooting messaging bridges that I've used in the past here: http://e-docs.bea.com/wls/docs81/faq/msgbridge.html#251107
          ...and the general configuration reference for messaging bridges is here, if you haven't gone there already (apologies if you have) - http://edocs.bea.com/wls/docs81/ConsoleHelp/messaging_bridge.html#1107082
