Message types

 

JMS provides several message types, each of which embodies some knowledge of its content. To avoid referring to the vendor-specific class names for the message types, methods are provided on the Session object for message creation.

In the sample program, a text message is created in the following manner:

System.out.println( "Creating a TextMessage" );
TextMessage outMessage = session.createTextMessage();
System.out.println("Adding Text");
outMessage.setText(outString);

The message types that can be used are:

• BytesMessage

• MapMessage

• ObjectMessage

• StreamMessage

• TextMessage

Details of these types are in Package com.ibm.jms.
