New Articles
By Rod Johnson
This article looks at the Spring J2EE application framework, its architectural benefits, and its scope. It describes Spring's features, such as its Inversion of Control container, O/R mapping integration with Hibernate 2.x and JDO, and its data access and transaction management abstractions. It also looks at Spring's AOP and MVC web frameworks and its support for implementing and accessing EJBs.
By Ernest Friedman-Hill
Jess is a rule engine and scripting environment for the Java platform. JSR 94 is a developing JCP standard for interfacing rule engines to Java software. The reference implementation of JSR 94 is a driver for Jess; with it, you can connect Jess to Java software. This article shows you how to apply the javax.rules API to access Jess from your J2EE or J2SE applications.
This newsletter is sponsored in part by DataPower Free Whitepaper & Webcast on Portal Performance and XML. Today's dynamic enterprises are using XML-based Portals for all the obvious reasons: Data Aggregation, Device/browser independence, User Customization, to separate Presentation from Content, Single-source publishing & content reuse. Learn how leading Fortune 500 companies are optimizing the performance for their XML-based Portals, minimizing their cost, and reducing their development cycles: Register here
TSS Surveys
TheServerSide recently emailed a small group of TSS subscribers, on behalf of the data connectivity company, DataDirect Technologies, to take part in a survey on their JDBC and XML usage habits. The results have been published. Some of the questions asked were what JDBC 3.0 features are important, what tools people use to access data and integrate it with Web publishing systems, and how people are using SQL/XML and XQuery in their applications.
Tech Talks
Topic: J2EE Patterns and the eBay Case Study
John talks about the new patterns in his book 'Core J2EE Patterns'; he discusses the Domain Store and the Business Object, and looks at how metadata will change the way we write patterns. He describes how his team rearchitected eBay 3.0, performance requirements that drove eBay's design, and why eBay chose J2EE over .NET for their architecture.

Patterns
By Derek C. Ashmore
The MVC pattern seems to be derived from standalone GUI-applications as we know them from Windows etc. However, in serverside applications you often need to call the same control from a servlet/JSP, a Web Service, a JMS listener, a Legacy System listener, FTP file upload watchers etc. This modified version of the MVC pattern splits the control domain into controls and dispatchers.
Key J2EE Industry Headlines
BEA Launches WebLogic Enterprise Security
BEA has announced WebLogic Enterprise Security (WLES), an application security infrastructure product that allows centralized policy control and visibility but features a distributed architecture that doesn't hinder application performance. WLES' features include authentication, identity assertion, credential mapping, dynamic role mapping, rules-based parametric authorization, etc.
webMethods acquires Web Services tools maker The Mind Electric
Integration company webMethods has announced the acquisition of Web services tool vendor The Mind Electric (TME). TME founder Graham Glass will become webMethod's new CTO. TME's Glue will be marketed as webMethods Glue and the Gaia product will be named webMethods Fabric. webMethods also acquired portal vendor DataChannel.
JSR 168 Portlet Specification Formally Approved
The JSR 168 Portlet API spec has recieved final approval from the J2SE/J2EE Executive Committee. All the executive committee members voted "Yes" with no comment, except Apache who didn't vote, and IBM who voted "Yes" with a comment on licensing terms.
IBM hits out at .NET technology
IBM has hit out against .NET. They are claiming that WebSphere is far superior to .NET, and using the message that "IBM started from server technology. Microsoft has enhanced desktop technology and applied it to servers". They are using a Gartner study as ammunition, which said that .NET was not for demanding enterprise platforms.
JOnAS 3.3 has been released. This is the last major release before JOnAS 4 (full J2EE 1.4 support) which is expected at the very beginning of next year. JOnAS 3.3 already provides some J2EE 1.4 features such as Web Services deployment and EJB 2.1 Timer Service early implementation.
Announcing JFox 1.0 Open Source J2EE Appserver
JFox is an Open Source, J2EE-based application server written by the Chinese Open Enterprise Foundation. JFox 1.0 DR3 adds an improved MX Http Console, integrates JTA into the EJB container as well as an XADataSource, and now supports Mysql, Oracle, and DB2.
