Use Web services to integrate Web applications with EISs
by Volker Weber
Web services expose business processes to bolster object-oriented and component-based programming with a services-based model. You can enhance your current programming model to support Web services by adding a service contract. The service contract completely separates a system interface from its implementation. Sun Microsystems' Java 2 Platform, Enterprise Edition (J2EE) and Microsoft's .Net frameworks both provide powerful platforms on which to build and support Web services. This article explores how to leverage both platforms to integrate enterprise information systems (EISs) and Java-based Web applications. Find out how Web services, the Model-View-Controller (MVC) pattern, and the J2EE Connector Architecture (JCA) all play a major role in this integration game.
