Chapter 4. Creating a Provider Endpoint
Abstract
A provider is an endpoint that sends messages to remotes endpoints and, depending on the message exchange pattern, waits for a response. They use the Spring framework's
JMSTemplate interface.
Important
The Java Business Integration components of Red Hat JBoss Fuse are considered deprecated. You should consider migrating any JBI applications to OSGi.

A provider endpoint plays the role of a provider from the vantage point of other endpoints inside of the ESB. As shown in Figure 4.1, “Provider Endpoint”, a provider endpoint receives messages from the NMR and places them onto a JMS destination. If the NMR message is part of an in-out message exchange, the endpoint will listen for the response on a reply destination.

The JMS binding component has two types of provider endpoints:
- Generic
- The generic provider endpoint can handle any type of message data. It is configured using the
jms:providerelement. - SOAP
- The SOAP provider 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-providerelement.TipThe Apache CXF binding component's JMS transport is better adapted to handling SOAP messages, but offers less control over the JMS connection.
