EJB DESIGN PATTERNS


EJB Design Patterns Free PDF Available for Download
By Floyd Marinescu

I am pleased to announce that TheServerSide's book EJB Design Patterns is now available for free download in PDF format. EJB Design Patterns was the #2 book at Java One 2002, and held the #1 Java book position on Amazon.com for weeks since the book was released in March. Thank you members of TheServerSide, for all your help in creating this book.

EJB Design Patterns goes beyond high-level design pattern descriptions into critical EJB-specific implementation issues, illustrated with source code implementations. The book contains a catalog of twenty advanced EJB patterns and provides strategies for mapping application requirements to patterns-driven design, J2EE development best practices, and a collection of EJB tips and strategies, and other topics such as Build-System best practices using Ant, JUnit testing strategies, using Java Data Objects (JDO) as an alternative to entity beans, and more.

FEATURED TECHNICAL ARTICLES


Improving J2EE Application Performance
By Scott Marlow

This article describes how to achieve a high level of performance in a J2EE application, independent of which Application Server you use. A structured approach to improving performance will be described that ranges from broad strokes (monitoring J2EE Application Server resource usage) to fine strokes (finding bottlenecks in the application). After reading this article you will find that performance isn't just an occasional activity - performance is a state of mind.

NEW BOOK CHAPTERS FOR PUBLIC REVIEW


TheServerSide is pleased to announce that it will be hosting a book review process for the upcoming book on Struts, an O'Reilly book by Chuck Cavaness. Chapters from the book will be posted to TSS as they are written for public feedback.

Chapter 10 - Exception Handling
First Public Review Posting

This chapter will look at how you can properly use the Java exception handling mechanism within your Struts applications to help make your applications more industrial-strength and allow them to gracefully respond when things don't go as expected. Special attention will be given to the differences between performing the exception handling programmatically and using the new declarative feature added to the new version of Struts.

NEW J2EE PATTERNS


Validation of Data Transfer Objects
By Matthew Brown

Validation of Data Transfer Objects was creating duplicative code that is not easy to maintain. We found a solution to the problem by isolating our validation methods in a separate class and using the java reflection API to invoke the validation methods dynamically.

NEW APP SERVER REVIEWS


Do not use WebSphere unless you are Blue
By Nader Aeinehchi

Having had close relationship with IBM for years, I had expected more. But several months with WAS has been nothing but disappointment. Our code is a direct modification of the SUN PetStore. Our code has worked under several application servers. We have primarily developed under Orion/OC4J. The code has worked for some time under WAS 4.0, but stopped working. If you heavily rely on IBM technologies like DB2, OS390, Lotus, CICS etc, you should definitely stick to WebSphere. If not, please do yourself a favour, try something else.

KEY J2EE INDUSTRY HEADLINES

Application Server Marketshare: Behind The Numbers

Gartner last week released numbers indicating that the application server market only grew by 20% in 2001 (compared to 100% in previous years), as well as pegging 2001 marketshare numbers at: IBM 31%, BEA 34%, Sun 9%, with the rest divided between Oracle, HP, and competitors. A new article on internetweek steps back and looks at the trends driving the appserver market.

.NET vs. Oracle's Java PetShop Benchmark Round III

At JavaOne in March, Oracle and Sun announced new Java Pet Store benchmark numbers showing a revised J2EE-based Pet Store beating the .NET Pet Shop in performance. Last week VeriTest conducted an audit of the latest benchmark data, and re-tested the .NET Pet Shop using Oracle's load test scripts. The .NET Pet Shop was found to be faster.

CSIRO Releases ECPerf kit for JBoss Application Server
