Tales From TheServerSide
TheServerSide has added to its J2EE portability cluster, by launching an additional Sun ONE Application Server 7 server into the group. The TSS application was ported to Sun ONE, and has joined the distributed cluster (adding to the BEA WebLogic and Oracle9iAS servers). We have written up the issues that came up with porting to Sun ONE.
TheServerSide as an application now stands as a great example of J2EE portability in action. It's a production system with heavy loads (over 2 million pageviews/month) that runs with the same J2EE application binaries deployed across different vendors servers. Each server is J2EE 1.3 compliant and runs TSS in a consistent fashion.
Featured Articles
By Joseph Chandler & Jason Thurow
This article presents a simple architecture to solve the problems presented by XSL needing to be well formed XML when working with the Entity references, import and include mechanisms of XML and XSLT. The solution makes use of the javax.servlet.Filter class, JSP technology and XML and XSLT. It involves processing the XSL as a JSP page. By doing this the developer can utilize the JSP include tags as well as everything else JSP technology has to offer, producing a well-formed XSL file that can then be compiled into a Template class, useable by an XSLT processor.

Tech Talks
Topic: J2EE Development Tools
Ted looks at trends in J2EE development, tools in the Java and UML space and comments on the industry trend towards improving UML strategies as highlighted by IBM's acquisition of Rational and Borland's acquisition of Togethersoft. He discusses the technical benefits of frameworks and the influence of JavaServer Faces, Apache Struts and other Web frameworks on development tools. He also looks at the Eclipse initiative, the philosophy behind it, and emphasizes the need for standards such as JSR 198, a standard extension API for IDEs.
TMC Training Video
This short video is good for J2EE programmers who are using databases in their deployments. It will help you better understand how to use transactions, an important mechanism to ensure your data has integrity. Owen Taylor, Senior Instructor at The Middleware Company, is seen teaching actual courseware.
New Public Review Chapters
Excerpted from Sun Microsystems Press and Prentice Hall's Core JDO
The JDO query facility consists of an API that can be used to programmatically locate information and a query language called the JDO Query Language (JDOQL) that defines the grammar for structuring queries. The 'Finding Your Data' chapter from the Core JDO Book-in-Review looks at the query facility, and how to retrieve and query the underlying datatstore using the API and JDOQL.
Excerpted from Manning's AspectJ In Action, by Ramnivas Laddad
Using AspectJ with the Java Authentication and Authorization Service (JAAS) allows you to modularize your access control implementation into a few modules, separate from the core system logic. JAAS still performs the core part of authentication and authorization; however, by using aspects to specify operations that require access control, API calls are reduced.
TheServerSide Symposium
For the first time ever, founders and chief architects of all the major enterprise open source java groups are getting together to discuss issues important to the Java community. Join Bill Burke (lead architect of JBoss 4), Mike Cannon-Brookes (founder of OpenSymphony group, Java blogs), Gavin King (architect of Hibernate), Vincent Massol (Apache Struts committer and Cactus founder), and Christophe Ney (president of ObjectWeb consortium) as they discuss quesitons such as the latest innovations open source is bringing to Java, what combinations of projects gives the ultimate J2EE development framework, how to choose between so many frameworks, open source licenses and revenue models, etc.
If you're thinking about benefiting from this incredible show, you should register by April 30th. If you register in April you will get the whole symposium for $1195 ( $300 discount) and you'll get to choose from over 15 books written by J2EE experts speaking at the show and meet them in person to get a personally autographed copy. The book and discount will not be available after April 30th.
TMC 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, contact sales@middleware-company.com, or call toll-free +1 (877) 866-JAVA for more details. Do it now while it's fresh on your mind!

Marc Fleury Publishes WHITE: Why I love Professional Open Source
Marc Fleury has published the "White", the second paper in his "Blue, White, Red" series.

BPEL4WS submitted to OASIS Standards Body
BEA, IBM, and Microsoft have submitted the Business Process Execution Language for Web Services (BPEL4WS) to the OASIS standards organization this week, and a new technical committe is being formed at OASIS to continue work on the spec. A rival spec, the Web Services Choreography Interface, is being worked on at W3C.
Netcraft Java Servlet Engines Report
Netcraft recently published a note on stats it has collected on servlet engine usage around the net. According to Netcraft, JSP has been the fastest growing scripting technology after ASP.NET last year, but JSP sites are often bigger, more complex, and better funded. Tomcat and Resin were the #1 servers.
