From DeveloperWorks, Configuring SCA HTTP binding to enable real-life scenarios
You can use HTTP bindings supported by IBM® WebSphere® Integration Developer Version 6.1 in many common real-life integration scenarios involving Service Component Architecture (SCA) applications. For example, by properly configuring the HTTP bindings you can expose SCA applications as a simple HTTP URL using HTTP export binding; enable SCA applications to consume third party XML Web services using HTTP import binding; and use HTTP bindings to integrate multiple SCA applications.
Using a downloadable, hands-on, sophisticated example SCA application, you see how to configure the key HTTP binding attributes to enable these scenarios. It is intended for WebSphere business integration consultants and developers who want to integrate SCA applications using HTTP infrastructure.
The HTTP binding is new in WebSphere Process Server v6.1. It appears to support REST and includes an example of mashing-up Atom feeds. Enjoy.
