MDB with remote MQ manager

Question

Hi -
I'm using WL 10.0 which will host some MDBs (possibly EJB 3.0) to consume messages - these MDBs need to digest messages from a foreign JMS provider - in our case we need to connect to IBM MQ 6.0 Queue Manager hosted on a remote machine elsewhere in the infrastructure.
I've seen some articles on setting up foreign JMS providers in WL 10 - understand that's the process, but are there concrete steps/examples on how to accomplish that?
Thanks,
James

Hi Andrew,
In this case you would treat the SAP JMS Provider hosting the remote queue on box B as a "third party" JMS provider, as described in this [document|http://help.sap.com/saphelp_nwce711/helpdata/en/46/6e52823abf7185e10000000a114a6b/frameset.htm].
You have to use the first option, <context-factory-type>. In case both CE systems are of the same version, you don't even have to deploy a JMS library as described in step 4 and can leave the <library-name> element out.
Here is a sample jms-resources.xml:
<?xml version=u201D1.0u201D encoding=u201DUTF-8"?>
<jms-resources xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="jms-resources.xsd">
   <connection-factory>
      <name>MyConnectionFactory</name>
      <context-factory-type>
         <initial-context-properties>
            <initial-context-factory>com.sap.engine.services.jndi.InitialContextFactoryImpl</initial-context-factory>
            <provider-url>hostB:50004</provider-url>
            <security-principal>Administrator</security-principal>
            <security-credentials>admin_password</security-credentials>
         </initial-context-properties>
         <link-factory-name>
            jmsfactory/default/XAQueueConnectionFactory
         </link-factory-name>
      </context-factory-type>
   </connection-factory>
   <destination>
      <name>MyQueue</name>
      <type>javax.jms.Queue</type>
      <external-destination-type>
         <link-connection-factory>
            MyConnectionFactory
            <!-- This name has to be the same as the name of the connection factory -->
         </link-connection-factory>
      </external-destination-type>
   </destination>
</jms-resources>
Then, in the MessageDriven annotation you just need to use the above connection factory and destination.
HTH!
