Using Atom bindings in SCA applications

You can use an Atom binding in a Service Component Architecture (SCA) application to expose collections of data as an Atom feed or to reference existing external Atom feeds.

Before you begin

If you are unfamiliar with the Atom protocol, refer to documentation on the Atom Syndication Format, an XML-based document format that describes web feeds, and the Atom Publishing Protocol, a protocol for publishing and updating web resources.

About this task

Use the Atom binding to work with services that provide or consume entries described in the Atom Syndication Format and Atom Publishing Protocol. An SCA component can reference existing external web feeds defined using the Atom protocol and work with them inside a Java implementation. Also, you can use the Atom binding to compose new services and expose them as an Atom feed.

This topic describes the following procedures:

Procedure

What to do next

Deploy your SCA component in an application.

If the Atom feed service is deployed to a cluster and the target attribute, @target, is used to point to the service, the target URI resolves to an HTTP port for an individual cluster member. To maintain failover and load balancing in this situation, you can use an absolute URI on the binding.atom element that points to a proxy server endpoint rather than the target attribute on the reference element. For more information, see the topics on resolving SCA references and on routing HTTP requests to an SCA service when using an external web server.
