The WebSphere MQ resource adapter

 

The J2EE Connector Architecture (JCA) provides a standard way of connecting applications running in a J2EE environment to an Enterprise Information System (EIS) such as WebSphere MQ or DB2. The WebSphere MQ resource adapter implements the JCA 1.5 interfaces, and allows JMS applications and message driven beans (MDBs), running in an application server, to access the resources of a WebSphere MQ queue manager. The resource adapter supports both the point-to-point domain and the publish/subscribe domain.

The WebSphere MQ resource adapter supports two types of communication between an application and a queue manager:

Outbound communication

An application starts a connection to a queue manager, and then sends JMS messages to JMS destinations and receives JMS messages from JMS destinations in a synchronous manner.

Inbound communication

A JMS message arriving at a JMS destination is delivered to an MDB, which processes the message asynchronously.

The WebSphere MQ resource adapter is supported on all WebSphere MQ Version 6.0 platforms except z/OS. We can install it on any application server that is certified as compliant with the J2EE 1.4 specification. Using the resource adapter, an application can connect to a WebSphere MQ V6.0 queue manager in either client mode or bindings mode, or to a WebSphere MQ V5.3 queue manager in client mode only.
