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:

A dependent object can be a simple self-contained object or may in turn contain
other dependent objects. The life cycle of a dependent object is tightly coupled to
the life cycle of the coarse-grained object. A client may only indirectly access a ...
A coarse-grained object can be a Java object contained in the Composite Entity.
Or, the Composite Entity itself can be the coarse-grained object that holds
dependent objects. These strategies are explained in the “Strategies” section.
The Value Object pattern is used to serialize the coarse-grained and dependent
objects tree, or part of the tree, as required. • Session Facade If dependent
objects tend to be entity beans rather than the arbitrary Java objects, try to use
