Featured Interview
Aslak Hellesoy, project administrator for XDoclet and creator of Middlegen, discusses the current challenges the XDoclet project faces and its future goals. He looks at the changes and new features in the XDoclet 2 release, and compares his own xJavaDoc API with Sun's JavaDoc API. In his opinion XDoclet is complementary to Model Driven Development but is not appropriate for Aspect Oriented Programmming.
Tech Talks
Topic: Clustering in J2EE
In this interview Dean Jacobs looks at stateless and stateful services in a clustered environment. He discusses entity bean caching in Weblogic, clustering techniques using JMS and Message-driven beans, and failover with cluster-aware EJBHome stubs and EJBObjects. He examines singleton services, different types of clustering topologies, and looks at some of the challenges presented by Web services.

New Public Review Chapters
TheServerSide is pleased to announce that we will be hosting public review chapters for the upcoming book AspectJ In Action (Manning), by Ramnivas Laddad. AspectJ in Action is a practical guide to AOP and AspectJ. The reusable code examples that are provided will enable quick implementation of functionality in your system. The book provides an in-depth coverage of AOP and AspectJ, looks at design patterns and idioms, solutions to real-world problems, provides reusable code content, and talks about AspectJ version 1.1
Excerpted from Manning's AspectJ In Action, by Ramnivas Laddad
With AspectJ, a general-purpose, aspect-oriented extension to the Java programming language, you implement the core concerns using the Java programming language, and you use the extensions provided by AspectJ to implement the weaving of crosscutting concerns. This chapter, complementary to the chapter on Syntax Basics, introduces you to the core concepts that will get you started with AspectJ. giving you enough information to start writing simple code with AspectJ.
Excerpted from Manning's AspectJ In Action, by Ramnivas Laddad
Complementary to the introductory chapter, this chapter continues with a more detailed discussion of the constructs of pointcuts and advice, their syntax, and their usages. It also examine a few simple programs that will help strengthen your understanding of the AspectJ constructs. It then discusses static crosscutting. After reading this chapter, you should be able to start writing short programs in AspectJ.
Excerpted from Core JDO (Sun Micorsystems Press, Prentice Hall)
by Keiron McCammon, Heiko Bobzin, Sameer Tyagi, Michael Vorburger
This chapter looks at the EJB component model and its relationship to JDO. It addresses various implementation topics and provides extensive source code examples. The goal of this chapter is not to simply show 'how' to code EJB and JDO together, but also to help you decide if the combination of these two APIs makes sense for you.
Excerpted from Core JDO (Sun Micorsystems Press, Prentice Hall)
by Keiron McCammon, Heiko Bobzin, Sameer Tyagi, Michael Vorburger
This chapter defines the different levels of security, their requirements and objectives. It looks at the Reference Enhancer,and examines the rules and measures defined by JDO to secure an application. The chapter finally looks at application level security and how J2EE and JDO work together regarding security.

TheServerSide Symposium
Boston, June 27 - 29 Weekend
Fellow TSS members, TheServerSide Symposium, your J2EE conference is going strong. The second deadline just passed (saving $400 by March 31st) and we've gotten almost twice the number of registrations we expected this early out. Luckily, there are still many spots left in this limited-attendance J2EE technical conference running the June 27-29 weekend in Boston, MA. Here is another small sample of the great speakers/talks that will be presented at the symposium:
Pattern Frameworks and Micro-Architectures - This talks focuses on putting patterns together to form larger design solutions. By looking at groups of patterns and patterns applied to macro problems, this talk will demonstrate the new areas of using patterns to drive larger design solutions. This talk will also dive deep into the new Web Worker workflow pattern and demonstrate the rationale behind J2EE patterns and micro architectures.
John Crupi: Co-Author, Core J2EE Patterns. Distinguished engineer and Chief Java Architect at Sun.
Rich Internet Applications: Evolving the Client and Presentation Tiers - This session explores the vision and value of Rich Internet Applications (RIA's), covering aspects such as occasionally-connected clients, client-hosted Web services, client-side portals, and peer-to-peer influences. It investigates the RIA relationship with Web services, integration into J2EE patterns and methodologies, deployment concerns, and includes a survey of popular RIA strategies.
Sean Neville: JCP Executive Committee representative for Macromedia, EJB 2.0/J2EE 1.4 expert group member. Flash Remoting for J2EE/.NET architect.If you're thinking about benefiting from this incredible show, you should register by April 30th. This is a limited (500 person) event, and this newsletter alone is received by over 130,000 people!
