Summary

The WebSphere programming model is tuned to four basic models of e-business computing. This builds on the J2EE programming model for multi-tier distributed computing. It simplifies the task of leveraging your legacy investments. It provides a solid foundation for modeling your business functions and processes, and integrating your lines of business and business relationships. WebSphere is crystallizing first-class support for service-oriented business structures.

At this point you should have gained a broad view of the entire WebSphere programming model – including the primary models of computing supported by WebSphere, the basic development process, and roles pertaining to components supported by WebSphere. You should now know that the WebSphere programming model consists of the Java 2 Platform, Standard Edition (J2SE) and Java 2 Platform, Enterprise Edition (J2EE) standard features, web services, core extensions, and other programming model extensions covering functions like workflow management, rules processing, threading, internationalization, and so on. Finally, you should have a sense of what to avoid in your programs, and the basic principles of good programming. All of this should prepare you for the detailed discourse offered through the remainder of this book.
