Instead, SCA gives you a model to define interfaces, implementations, and references in a technology neutral way, letting you then bind these elements to whichever technology specific implementations you choose. For example, we can define our interface in Java, and our implementation can be applied as a BPEL process, or we can have my interface as a WSDL document and our implementation could be a Java™ class. Figure 1 illustrates how SCA is used in IBM WebSphere Process Server.Out of the box, WebSphere Process Server lets integration developers have various different implementation technologies and enables you to expose t...

Building SOA Solutions with Service Component Architecture

In the previous article (part 1 in WebSphere Journal vol: 3. iss: 4) we began to build an SCA project in WebSphere Process Server. Here in part 2 we pick up the discussion. To see the associated images, please view the article online at www.ibm.com/developerWorks/websphere. d.  The business object is defined using standard XML schema type. You can open the business object using an XML editor to see it. (You can open the business object in a text editor by right clicking it and selecting Open with => and the editor of your choice.) e.  Save and close the Business Object Editor. f. ... (more)
