Introduction to Consumer Endpoints

Where does a consumer fit into a solution?

Consumer endpoints play the role of consumer from the vantage point of the other endpoints in the ESB. As shown in Figure 3.1,consumer endpoints listen for messages on a JMS destination. When the message is received, the consumer endpoint passes it onto the NMR for delivery. If the JMS message is part of an in-out message exchange, the consumer endpoint will place that message into a reply destination for delivery to the originator of the JMS message.

Types of consumer endpoints

The JMS binding component offers three types of consumer endpoint:

Generic

The generic consumer endpoint can handle any type of message data. It is configured using the jms:consumer element.

SOAP

The SOAP consumer endpoint is specifically tailored to receive SOAP messages. It uses a WSDL document to define the structure of the messages. It is configured using the jms:soap-consumer element.

	Tip
	The FUSE Services Framework binding component's JMS transport is better adapted to handling SOAP messages, but offers less control over the JMS connection.

JCA

The JCA consumer endpoint uses JCA to connect to the JMS provider. It is configured using the jms:jca-consumer element. For more information on using the JCA consumer endpoint see Using the JCA Consumer Endpoint.
