Tales From TheServerSide
Introducing Tales From TheServerSide - Your J2EE Cartoons
The Great ECperf Race
TheServerSide is pleased to present a new cartoon series, "Tales From TheServerSide", a biweekly comic which will form the first ever collection of J2EE cartoons! Featured this week is 'The Great ECperf Race'. Inspired by a turbulent year of ECperf benchmark tests, this cartoon is a satire on what at times seemed like a back and forth race between the big vendors.

Advanced Classloading in J2EE
By David Bosschaert & Arne Koschel
This article will describe a classloading system that combines ease of use with efficiency and compliant behaviour in order to deal with issues such as 3rd party library integration which have conflicting classes, use of remote stubs, etc. This classloading approach also contains a mechanism to separate internally used libraries from user-installable libraries that could potentially conflict with each other. The classloading techniques in Iona's Orbix E2A Application Server will be illustrated as an example and their usage demonstrated.

Monson-Haefel's Guide to Enterprise JavaBeans - EJB 2.1 Web Services (Part 2)
By Richard Monson-Haefel
EJB 2.1 Web Services (Part 2) looks at SAAJ (Soap with Attachments API for Java) which enables you to build object-oriented representations of Soap messages, including attachments. The section on SAAJ provides a quick overview and an example of its use. The second half of this column looks at why the JAXM API didn't become a part of J2EE.

Eduardo Pelegri-Llopart - Java Web Services Developer Pack Architect, Sun Microsystems
In this interview, Eduardo describes the Java Community Process (JCP) and the role of a spec lead. He talks about Sun's Web services strategy, and how current vendors' approaches to building Web services differ from that of Sun. He describes how developers can use the different JAX API's in their projects, and discusses the role of JAX-RPC, JAXM, and JAXR. He also looks at Web services support in J2EE 1.4.

Enterprise Java Education Strategies
Do the managers at your company understand the J2EE buzzwords well enough to have intelligent conversations?
Most developers and managers have very poor communication. Often times it's because the manager is not familiar with the techno-babble that developers use, such as J2EE, load-balancing, weblogic, XML, JSP, taglibs, and more. Well, that doesn't have to be true anymore! Introducing Enterprise Java for Managers, a 2-day course that your manager can take to learn the lingo!
This course is offered exclusively by The Middleware Company, and can be held at your site (for a bunch of managers to take at once) or your managers can come to us to take it. Do your manager a favor - forward this email to them, and encourage them to visit http://www.middleware-company.com/training/java4Managers.shtml for more details. Do it now while it's fresh on your mind!

New Patterns
Generic Entity Beans
By Edwin Mol
This is an extention to the Value Object Pattern. The technique explained here shows how to make your entity beans more generic, such that things like concurrency control and data updates are done at a higher level and only need to be implemented once.
Read more on this pattern.
Dynamic Entity Model
By Eirik Grønsund
How can an entity bean client manipulate persistent data without implementing the "Crud" and navigation operations for the model elements in a data model. The pattern provide a generic interface that allows a generic set of model elements to be defined and used for data transfer and traversal of the data model without any implementation of the interface.
Read more on this pattern.
Application Context
By Adolfo Rodriguez
This pattern applies to any MVC compliant apps. Usually, data necesary for presentation use is spread along separate variables in the presentation tier. This pattern implements a main data holder for all the client tier data which deal with presentation logic. Business logic and backwards layers can collect data for business logic from this data holder.
