This topic provides an overview of what is involved in sending messages between a WebSphere MQ network and a WebSphere Application Server.
If you work in a WebSphere Application Server environment, where messages are exchanged between applications across a service integration bus, you might want to connect to applications in another messaging environment, WebSphere MQ. Using the WebSphere MQ link, exchange of point-to-point messages, and publish and subscribe is possible between WebSphere Application Server and a WebSphere MQ network, where the WebSphere MQ network is regarded as a "foreign bus". To identify the a supported version of WebSphere MQ, see the supported hardware and software Web page at http://www.ibm.com/support/docview.wss?rs=180&uid=swg27006921.
The WebSphere MQ link is defined on a messaging engine in a service integration bus. This simplifies message exchange because the messages are automatically converted so that their characteristics are either retained, or mapped to similar settings. There are some situations where the two systems work differently, and it is possible to select from the available conversion options.
Whichever route you implement, the requirements are the same: the requirements of the receiving WebSphere MQ destination must be recognized, and the message must be properly transformed. This is what the WebSphere MQ link is designed for. WebSphere MQ link operates on a destination in a service integration bus, and interoperates with the WebSphere MQ network, which it regards as a foreign bus. It handles both point-to-point and publish and subscribe messaging.

Because it is necessary to know the properties of the WebSphere MQ applications with which your applications will interoperate, you should work with your counterpart (either an administrator or a programmer), when designing applications. Also refer to the WebSphere MQ publications library at the WebSphere MQ publications site.
