Enterprise Java Programming with Websphere. [Englisch] [Taschenbuch]

While most books focus on Enterprise JavaBeans (EJB) and related standards without looking at particular Java 2 Enterprise Edition (J2EE) tools, this title zeros in on IBM's popular VisualAge and WebSphere products for building and deploying Java software. The book does a good job of explaining the higher-level principles when it comes to Java standards like servlets, JSPs and EJBs. The more abstract material on the best ways to combine these front-end and back-end technologies is anchored by chapters that show how to use the real IBM tools in action.

Sections on modelling EJBs, for example, show you how to build real EJBs in VisualAge (including some fine material on associations that will let you model even complex database schemas with Java components). Another plus is material on the specifics of deploying beans on the WebSphere platform, including tips on editing XML descriptor data. With today's J2EE standards, the genius is in the details. This book strikes a good balance between theory and practical advice. It gives you some of Sun's current best practices, like the Model-View-Controller (MVC). With fast-moving and useful tutorials on servlet JSP and EJB standards, the authors also discuss layering of components on the server to achieve the separation of presentation and business logic, a must for today's Java Web applications. Patterns and other strategies for making sure you separate the tiers are also introduced.

By anchoring a state-of-the-art tour of Java with samples using real IBM tools, this title provides what Java developers need to use JSPs and EJBs effectively in real projects to solve real business problems. It's quite simply one of the best available tutorials for learning how to build successful Web applications in Java. --Richard Dragan
