Bitter Java Free PDF Available for Download
By Bruce Tate
Now you can get the free PDF download for Bitter Java! TheServerSide.com and Manning Publications have partnered to offer this exclusive opportunity to TheServerSide.com members.
It is a well-known fact that most software projects fail. Drawing important lessons from failure is the goal of Bitter Java, a systematic account of common server-side Java programming mistakes, their causes and solutions. Reusing design patterns is not enough for success: patterns are like partial maps of dangerous terrain. They help but don't prevent you from getting lost.

FEATURED TECHNICAL ARTICLES
Inheritance and EJBs
By Daniel O'Connor
This article will show how entity EJBs can be used effectively to represent business objects with inheritance and polymorphic behavior by delegating polymorphic business method calls to appropriate "derived" component instances. It will show you how to implement entity bean inheritance with three sample CMP EJBs. It will demonstrate a polymorphic finder query and a couple of polymorphic method calls. It will also show how these container-managed persistence beans can be mapped to a standard relational database schema.

JAXP: Coding for Parser & Transformer Independence
By Henry Chen
This introductory article will educate developers about the JAXP API, and provide them with a strong understanding of the pluggability layer that will allow their applications to switch between parsers at will. Two parsers: SAX (an event-based model) and DOM (a tree-walking model) are comparatively looked at. An overview of XSLT is also given.

NEW BOOK CHAPTERS FOR PUBLIC REVIEW
TheServerSide is pleased to announce that it will be hosting a book review process for Manning's "JMX In Action", by Ben Sullins and Mark Whipple and also an upcoming O'Reilly book on Struts, by Chuck Cavaness. Chapters from these books will be posted to TSS as they are written for public feedback.
JMX In Action Chapter 1 - Resource Management and JMX
First Public Review PostingThis chapter presents the basis for JMX, the definitions of some common JMX terms, and the essentials of JMX architecture.
Read/Review the chapter here.
JMX In Action Chapter 13 - Using JMX with the Java Message Service
First Public Review PostingThis chapter combines JMX technology with the Java Message Service (JMS) and uses a simple example to show how to add functionality to JMS applications using MBeans.
Read/Review the chapter here.
Struts Chapter 12 - Internationalization and Struts
First Public Review PostingThis chapter focuses on what it takes to make a Struts application available to customers from around the world, regardless of their language or geographical location. Like many other things in software development, planning ahead is the most important thing that you can do to help ensure success. After reading this chapter, you should be able to build Struts applications that make it possible to support a broad reach of customers.

Struts Chapter 9 - Extending the Struts Framework
First Public Review PostingOne of the biggest advantages of using a framework is the ability to extend and customize it based on the needs of the application. The Struts framework is no exception and it provides several very important extension points for developers to extend. This chapter takes a quick glance at several of those extension points and points out the benefits and a few downsides when extending the framework.

NEW J2EE PATTERNS
Reusable Data validation using EJB 2.0 Home Methods and BMP
By Riley Berton
The pattern is based on EJB 2.0 Home methods and builds on the detail object pattern. Once your EJB's have a working detail object, clients of the EJB can get and set these objects; we will need to write a validate Home method and a ValidationErrors class that can return potential validation errors
Read more on this pattern.
The Local/Dispatchable Command Pattern
By Richard Hill
When the EJB Command Pattern is used, commands are executed in the EJB container. However, this may not be desirable for all use cases. The solution to this problem is to define two types of command that offer different execution models, with one type of command executing in the local context and another being dispatched to the EJB container.
