Distributed software development, where the user interface is different from the business logic and business logic separate from the persistent data store, take some getting used to. BEA WebLogic Platform WebLogic Server 7 focused on itself, leaving other parts of the development environment for the coverage in place other locations. There are many examples of code, too, so readers can see what they need to do to get their J2EE applications running properly. Chapters tend to be comprehensive, beginning with the theory (explaining, for example, what is the entity bean for a unique and life cycle) and moves through the recommended way of writing bean-class-and container-managed persistence. Special coverage goes to the presentation logic, business logic, and perseverance, as well as Web Services in BEA environments and server administration.
