Endpoint listeners and inbound ports - entry points to the service integration bus

An endpoint listener is a Web service-enabled entry point to one or more service integration buses. An endpoint listener carries requests and responses between Web service clients and buses.

An endpoint listener is the point (address) at which incoming SOAP messages for a Web service are received by a service integration bus. Each endpoint listener supports a particular binding. Endpoint listeners are supplied with WebSphere® Application Server for the following bindings:

A request arrives at an endpoint listener. It is passed to an inbound port, at which point security and JAX-RPC handler lists can be applied, then sent on to the service destination. Responses follow the same path in reverse.

The endpoint listener acts as the ultimate receiver of a SOAP message. The resulting messages that pass across the service integration bus are not then SOAP messages, rather just the data and context that resulted from receiving the SOAP message.

Two instances of each type of endpoint listener are supplied with WebSphere Application Server so that, for each endpoint listener type, you can set up separate endpoint listeners for (for example) requests from your internal users and requests from your external users. Each endpoint listener is associated with a specific server or cluster, a specific set of service integration buses and (through inbound ports) a specific set of Web services. By restricting access to an endpoint listener, you can give different user groups access to different services. For example:
