Best Practices with The Expresso Framework
Using a framework to create a web application
By Peter Pilgrim
Why invent the wheel every time you develop an application in Java? Writing a J2EE web application is complicated enough; you would not write a linked list module in C++ every time you started a new project. You would rather use another person's implementation. The same reuse-idea surely applies to server-side web development. In this article, Peter Pilgrim, looks at the best practices of using one popular web application toolkit, Expresso Framework. The idea of using custom tags, JSP, and the MVC paradigm are suitable for other such frameworks. He will illustrate the best of practice through an on-line stock trading program example.

Deciding whether EJB is appropriate
excerpted from the new "Mastering Enterprise JavaBeans 2nd edition" book
By Ed Roman
A recent Gartner Group report cited companies overspent $1 billion on EJB last year, when they could have just gotten by with Servlets/JSPs. This motivates our next discussion: once you've decided whether server-side Java is the way to go, you then need to make the all-important decision: are you actually going to use EJB on this project? Or is EJB overkill

Mastering Enterprise Java Beans II
EJB Best-Practices and Performance Optimizations
1st Public Review Posting, By Ed Roman
In this chapter, we will discuss EJB best practices, which are tried-and-true approaches to designing, building, and working with EJB. By taking heed of these best practices, you will avoid common pitfalls that others have experienced in the past when building EJB systems. We'll also discuss performance issues when building EJB systems.

BMP and CMP Relationships
1st Public Review Posting, By Scott Ambler
In previous chapters, we looked at how to build entity beans using BMP and CMP. In this chapter, we'll heat things up and learn about relationships between data. Examples of relationships include an Order having one or more Line Items, a Student registering for a Course, and a Person having an Address. These relationships need to be defined and maintained for advanced data models.

EJB Design Patterns
Business Delegate
1st public review posting, By Floyd Marinescu
How can an intermediary between a client and the Session Façade be created to facilitate decoupling the client from the EJB layer?
Create a layer of Business Delegates: plain java classes that hide EJB API complexity by encapsulating code required to discover, delegate to and recover from invocations on the Session and Message Façade EJB layers...........

Data Transfer RowSet
1st public review posting, By Floyd Marinescu
RowSet provides a common interface for all query operations. By using a RowSet, all the clients can use the same interface for all data querying needs. No matter what the use case is or what data is being returned, the interface a client operates on stays the same. This is in contrast to having hundreds of client UI's tightly coupled to use case specific Custom DTO's. Whereas Data Transfer Objects need to be changed when the client's data access needs change, the RowSet interface remains the same..........

NEW J2EE PATTERNS
Schema-oriented message destination
By Ricky Ho
When a message producer sends a message to a destination (queue or topic), it wants to make sure that it is sending messages to a destination where the consumers can understand. Similarly, when a message consumer receives a message from a destination, it wants to make sure that it can understand all the messages it takes from the destination. The consumer application and the producer application need to agree upfront (at design time) what message structure will be produced or consumed.
