Core J2EE Patterns: Best Practices and Design StrategiesPrentice Hall PTR, 2001 - 459 ページ Over the last few years, Java 2 Platform, Enterprise Edition (J2EE) technology has emerged and matured as a standard platform for building enterprise applications.

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.

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:
