Web Application Development with JSP and XML: Part I Fast Track JSP
By Qusay H. Mahmoud
If you have had the opportunity to build Web applications using technologies such as Common Gateway Interface (CGI) and servlets, you are accustomed to the idea of writing a program to generate the whole page (the static and the dynamic part) using that same program. If you are looking for a solution in which you can separate the two parts, look no further. JavaServerTM Pages (JSPTM) are here.
JSPs allow you to separate front-end presentation from business logic (middle and back-end tiers). It is a great Rapid Application Development (RAD) approach to Web applications. This series of articles provides a hands-on tutorial explaining how to develop modern Web applications for today

SHAPE THE NEXT SET OF DEFINITIVE J2EE BOOKS
TheServerSide.com is hosting two new J2EE book projects: Mastering EJB II, and EJB Design Patterns. Chapters from these two new books will be posted to TSS as they are written for public feedback. For the first time ever you will be able to directly participate in the writing of these two influential books and personally influence thousands of developers who will learn from them.
How you can help
Chapters will be posted in Microsoft Word format. To review a chapter, simply type your additions/comments/corrections directly into the word document and mail it back to the authors. The word documents will be shipped with Track Changes set to on inorder for your comments to be integrated with the chapter. All emails to the authors other than these documents may be discarded.
Latest Public Review Postings:
Mastering Enterprise Java Beans IIEnterprise Java Beans Design Patterns
- May 24th: Session Beans, 1st review posting.
This chapter covers session beans in full detail, including the characteristics of session beans, what makes session beans unique, differences between stateful and stateless session beans, the rules for writing session beans, detailed lifecycle diagrams for how session beans work behind-the-scenes.
- May 17th: Best Practices for EJB Projects, second review posting.
To be successful at developing software with EJB/J2EE you need to consider far more than just the technology you are working with. The best practices presented in this chapter describe advice, proven in practice, to help you build EJB systems successfully. Practices are presented for project inception, building your system, and system transition. Each best practice describes issues pertinent to your EJB project efforts, putting it into context for you, and recommends leading-edge resources that explore those issues in detail.
- May 14th: Complex Persistence, 1st review posting
Most modern business applications require that you persist - create, retrieve, update, and even delete - objects, in this case Enterprise JavaBeans (EJBs). Persisting EJBs can be as simple as defining a few simple class-to-table mappings using an EJB container's persistence administration tool or as difficult as writing sophisticated Java source code. How complicated your persistence solution becomes is determined by a myriad of factors, including but not limited to the nature of the EJBs that you are developing, the persistence mechanisms (e.g. databases, files, you have at your disposal, and the schemas of those persistence mechanisms. In this chapter we explore the issues surrounding EJB persistence and explore the various approaches to persistence that you may employ within your EJB applications.

- May 14th - JDBC and RowSets for Reading, 1st review posting.
In an EJB system that uses a relational database in the backend, an EJB client needs to populate a tabular user interface (UI) with server side data, for display purposes. How can a client efficiently access, tabular, server side data? The solution is to perform listing operations on relational databases using JDBC, with RowSets for marshalling data to the client tier. Use Entity Beans for update operations.

EJB Versioning In a Cluster Environment
By Thierry Janaudy
The problem I am facing on projects is related to how to upgrade EJB bean in a cluster environment without shutting down the system. I describe here a pattern that may solve this problem.
