TheServerSide @ JavaOne 2003
By Dion Almaer, Nitin Bharti, Floyd Marinescu, Stuart Charlton, Doug Bateman, Frank Cohen
The turnout at this year's JavaOne was modest to say the least, but there was still no shortage of great technical sessions, grandiose keynotes, intense BoFs, boisterous parties, and conferences running in parallel (JBoss 2). 'Java Everywhere' was the predominant theme and there were many fascinating, forward-looking talks and panels about J2EE 1.4, EJB 3.0, J2SE 1.5, the JCP and the future of Java. TheServerSide has vividly captured this year's JavaOne in all it's grandeur and has given a technical synopsis of many of the important talks and discussions.

Featured White paper & Sample Chapters
By Chris Peltz & Claire Rogers
This white paper takes an in-depth look at the open-source tools that can be used to get started on Web services development. It walks you through the development lifecycle of how an existing Java asset is exposed as a Web service interface. The application is developed, deployed, and tested on an HP laptop running on Debian Linux. The MySQL database and the BEA JRockit Linux JVM are used. The Eclipse environment is used in the creation of the Java components, while Apache Axis and Tomcat are used to develop the Web service. Apache Ant and Eclipse are then used to deploy the Web service, and PushToTest TestMaker is used for testing.
Excerpted from Java Web Services Architecture
Learn about JAX-RPC, Service-Oriented Architecture and Transaction Management from chapters excerpted from 'Java Web Services Architecture'. 'JAX-RPC' looks at the JAX-RPC service model, data types and serialization, development and sending attachments over SOAP. 'Service-Oriented Architecture' examines SOA entities, the characteristics of SOA, and details interface design for services. 'Transaction Management' introduces you to the fundamental concepts behind transactions and looks at the challenges of using existing transaction models for Web services.

Tech Talks
Topic: EJB Design Patterns
In this interview, Floyd looks at how a typical framework employs many of the commonly used patterns mentioned his book, 'EJB Design Patterns' (2002, John Wiley and Sons). He discusses in detail several of these patterns such as the Session Façade pattern, the EJB Home Factory pattern, the Data Transfer Object (DTO) pattern, and the DTO Factory pattern. He looks at EJB 2.x's effects on design patterns, the role of entity beans in EJB 2.x, suggests Java Data Objects as an alternative to entity beans and discusses the challenges of writing a book.
This newsletter sponsored in part by Compuware Managing Web Services without SOA? On their own, Web Services solve some technical issues to do with platform incompatibility and distributed computing across the Internet, but also build a web of interdependencies and a potential management nightmare. In this report, analyst firm CBDI Forum strongly recommends adoption of SOA as part of the migration to Web Services. Download the free white paper now!
Key J2EE Industry Headlines
Red Hat Plans Open Source Java
Red Hat is in discussions with Sun about launching an open source version of the Java platform. Redhat's CEO has said that have been working for five years on open source versions of Java technologies such as Just In Time compilers and Java Virtual Machines in a clean room environment, and has requested the sponsorship of Sun to go ahead with the full-scale project.
Sun blasts IBM, debunks acquisition rumour, sells Redhat, & more
Last week Sun execs blasted IBM for "using Linux Torvalds" and exploiting the OSS community, expressed reservations about open-source Java, debunked any rumours about being acquired by IBM, and announced they will sell and support Red Hat Linux on x86.
Survey: Slow development cycles the #1 concern
Compuware recently unveiled the results of its 2003 IT Professionals Survey on Application Development. The study of 200 people found that slow development cycles were the No. 1 application development challenge. Among other interesting datapoints, about 2/3rds were using Web Services in some form on their projects.
TestMaker 4.0 ships with new test agent recorder feature
PushToTest has released TestMaker 4.0, a free open-source test utility and framework that for testing web apps(HTTP, HTTPS, SOAP, XML-RPC) and email systems (SMTP, POP3, IMAP). New to this release is a recorder that writes a complete test agent automatically, new charts and meters to visualize results, and a new Swing-based environment.
HP and Dell Commit to Shipping Java on PCs
Sun recently announced that it has signed deals with Dell and HP to ship Java on all of their consumer computers and notebooks, a move which counters Microsoft's decision to take Java out of Windows by Jan. 1, 2004. The move makes sense for Dell/HP as their customers will be able to browse Java-enabled sites without having to download a JVM.
NextApp Releases Echo 1.0, Sierra 1.0
Echo is an open-source platform for developing component-based, event-driven Web applications that rival the capabilities of rich-clients. Sierra, NextApp's first commercial offering for Echo, provides an array of Intranet-oriented components and a detailed sample application that demonstrates a complete Intranet.
