WebLogic Messaging Bridge
The WebLogic Messaging Bridge is a part of WebLogic Server that forwards messages from a "source" destination to a "target" destination. Out-of-the-box adapters are provided so that thesource and/or target may be a JMS destination. Either end can be a JMS topic or queue, and could be a server running WebLogic Server 5.1 or higher, or a foreign JMS provider. The WebLogic Messaging Bridge also provides interoperability between different versions of WebLogic Server.
Container-Managed Transactions for Message-Driven Beans
A message-driven bean (MDB) is a special type of Enterprise Java Bean (EJB) that pulls messages from a JMS queue or topic. The EJB container (WebLogic Server) is responsible for connecting to the JMS provider, receiving messages, and passing them to the MDB in the proper transaction context. This allows asynchronous events to be processed by a J2EE-based application, which was not possible in a standard way before MDBs..
WebLogic Server has supported MDBs since WebLogic Server 6.0. Version 6.0 SP1 of the server added support for foreign JMS providers. However, container-managed transactions could only be used with WebLogic JMS, so a foreign JMS provider could not participate in the WebLogic transaction.
