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:

EJBHome or EJBObject. When initialized without an ID, the BusinessDelegate
requests the service from the Lookup Service, typically implemented as a Service
The Service Locator can provide a getHome () method, which accepts as
arguments the JNDI service name and the EJBHome class object for the

This strategy suggests the use of property files and/or deployment descriptors to
specify the JNDI names and the EJBHome class name. For presentation-tier
clients, such properties can be specified in the presentation-tier deployment ...
