WebSphere Application Server implements two main messaging sub-systems. The default-messaging-provider is internal to WebSphere and the WebSphere MQ messaging provider which uses WebSphere MQ. First, we will cover the default messaging provider which is implemented by using a SIB. Then, we will move onto the WebSphere MQ messaging provider. To demonstrate use of the SIB and the default Messaging provider, we will deploy an application which will use JMS via the SIB. Before we deploy the application, we will need to set up the JMS resources required for the application to implement Java messaging using the Java Message Service (JMS).
