FEATURED TECHNICAL ARTICLES


A Friendly Game of Tug of War: XMLC vs JSP
By David H. Young

This article focuses on where JavaServer Pages and Enhydra XMLC are today and what they do to make the long term goals of the application architect achievable. After reviewing JSP, JSP Tag Libraries and XMLC, this article looks at a real world scenario on the use of push versus pull, then speculates on an assessment of how well these two strategies address Web application development today.

NEW BOOK CHAPTERS FOR PUBLIC REVIEW


TheServerSide is pleased to announce that it will be hosting a book review process for the upcoming book on Struts, an O'Reilly book by Chuck Cavaness. Chapters from the book will be posted to TSS as they are written for public feedback.

Struts Chapter 1: Introduction
First Public Review Posting

This introductory chapter discusses some preliminary concepts such as MVC, Model 2, and the idea of a software framework. The concepts presented in this chapter help to lay the foundation for the rest of the book.

Read/Review the chapter here.

Struts Chapter 2: Inside the Web Tier
First Public Review Posting

For Struts developers, understanding how the web container processes client requests is fundamental to having a deeper understanding of the framework itself. This chapter illustrates the various components that are part of the web container and what each component's responsibilities are.

NEW J2EE PATTERNS


Metadata-based code generator
By David Churchville

Problem: You need many instances of code that are functionally very similar, but different enough to resist factoring out commonality into utiltities or base classes.

Solution: Capture meta-data about the domain, and use this information to generate implementation code. Updates are made to the metadata so that code can be regenerated.

Read more on this pattern.


EJB Checksums instead of Version Number Pattern?
By Brian Wozny

Our company maintianed consistency/protected against concurrency problems for use cases which span transactions by using a method of checksum calculation which does not require a field to be added to the database tables. Our solution had nothing to do with the Java language or J2EE, but this may be a potential solution ... possibly EJB 2.1?

Read more on this pattern.


RTTI Killer Pattern
By Han Theman

In a recent design we needed the client to add various types of orders into a back-end database through EJB. Each order type is a subclass of Order. Examples of subclasses include AddOrder, MoveOrder and ConnectOrder. What we did was pass subclasses through baseclass references without resorting to manual RTTI (instanceof).
