XMS messages

This section describes the structure and content of XMS messages and explains how applications process XMS messages.

• Parts of an XMS message
  An XMS message consists of a header, a set of properties, and a body.
• Header fields in an XMS message
  To allow an XMS application to exchange messages with a WebSphere JMS application, the header of an XMS message contains the JMS message header fields.
• Properties of an XMS message
  XMS supports three kinds of message property: JMS defined properties, IBM defined properties, and application-defined properties.
• The body of an XMS message
  The body of a message contains application data. However, a message can have no body, and comprise only the header fields and properties.
• Message selectors
  An XMS application uses messages selectors to select the messages it wants to receive.
• Mapping XMS messages onto IBM MQ messages
  The JMS header fields and properties of an XMS message are mapped onto fields in the header structures of an IBM MQ message.
