Core J2EE Patterns: Best Practices and Design Strategies
Over the last few years, Java 2 Platform, Enterprise Edition (J2EE) technology has emerged and matured as a standard platform for building enterprise applications. While the platform has matured into a solid offering for developing and deploying enterprise applications, it does offer its challenges. As developers, often we confuse learning the technology with learning to design with the technology. In this book, senior architects from the Sun Java Center, Sun's Java consulting organization share with the reader their cumulative design experience with and expertise on J2EE technology.
The primary focus of the book is on patterns, best practices, design strategies, and proven solutions using the key J2EE technologies including JavaServer Pages (JSP), Servlets, Enterprise Java Beans (EJB), and Java Message Service (J.M.S) API. Other ancillary technologies like JDBC and JNDI are also discussed as relevant to their usage in these patterns. The J2EE Patterns catalog with 16 patterns and numerous strategies is presented to document and promote best practices for these technologies.
In addition to the patterns and strategies, the book offers the following:

As discussed in Chapter 1, some experts define a pattern as a recurring solution
to a problem in a context. These terms—context, problem, and solution—deserve
a bit of explanation. First, what is a context? A context is the environment, ...
We have also seen similar solutions emerge for these problems. While the
implementation strategies varied, the overall solutions were quite similar. Let us
discuss, in brief, our pattern identification process. When we see a problem and ...
Solution: Describes the solution approach briefly and the solution elements in
detail. The solution section contains two subsections: • Structure: Uses UML class
diagrams to show the basic structure of the solution. The UML Sequence ...
