The EJB Advocate: Is it ever best to use EJB components without facades in service oriented architectures?
The EJB Advocate evaluates using various forms of "facades," including POJOs, HttpServlets, session EJB components, message driven beans, and entity EJB Home methods, in an attempt to get at the heart of what makes up a good service oriented architecture implemented with J2EE components.

The EJB Advocate: Implementing loosely coupled SOA applications using Java EE
The EJB Advocate explores various forms of loose coupling in service-oriented architecture, with a focus on when it is best to take advantage of the asynchronous processing power provided by message-driven beans. 		Articles 07 Dec 2005  
 
The EJB Advocate: Which type of EJB component should assemble the data returned by a service?
The EJB Advocate takes a top-down view of service-oriented architectures in order to get to the bottom of whether a session or entity EJB component should assemble the data transfer objects returned by the service. 		Articles 17 Aug 2005  
 
The EJB Advocate: Making entity EJB components perform, Part 2
As discussed in last month's column, using poorly designed EJB components can lead to serious performance problems during system testing or (worse) in production. This month, the EJB Advocate shows how to use CMRs to get the benefit of using multiple related CMPs in a single unit of work. 		Articles 06 Apr 2005  
 
The EJB Advocate: Making entity EJB components perform
Using poorly designed EJB components can lead to serious performance problems during system testing or (worse) in production. The EJB Advocate shows how to design method signatures to minimize the "chattiness" between layers and get the most out of your EJBs. 		Articles 23 Feb 2005  
 
The EJB Advocate: Is EJB 2.x dead yet?
The EJB Advocate responds to a reader who declares that EJB 3.0 makes EJB 2.0 obsolete, and explores some of the new features of the EJB 3 specification, including the Java Persistence API (JPA). This exchange shows that while the benefits of these new specifications are good, they require you to make some simplifying assumptions that may not work for everyone. Since nearly all of these benefits can be provided as implementations of the EJB 2.x specification with the proper tooling, it is likely that EJB 2.x will be around for a while.

The EJB Advocate: Getting EJB cross references right
Trying to eliminate the use of EJB components by developers can lead to duplicate reference lists, broken encapsulation, and a maintenance headache. The EJB Advocate tries to ease the pain by showing how session EJBs go beyond providing just distribution, transactions, and security, and how they help make applications more maintainable and reliable.

The EJB Advocate: Practical uses for stateful session beans
Just when you think that you have no use for a given component, like a stateful session EJB, a scenario comes along where it is just the right thing to use. In this last column in the series, the EJB Advocate explores some tricky situations that sometimes come up with long running services. 		Articles 06 Dec 2006  
 
The EJB Advocate: SOA represents the next step in the evolution of component-based applications
Somehow the tables got turned! This month, the EJB Advocate finds himself in the position of advocating SOA-related specifications, such as Service Component Architecture (SCA), as much as those associated with Enterprise JavaBeans. 		Articles 20 Sep 2006  
 
The EJB Advocate: What makes a practice the best?
A reader questions the whole idea of "best practices" and, in the end, learns something new about application architecture, and why Enterprise JavaBeans is such a powerful concept that, unfortunately, many still do not fully exploit. 		Articles 21 Jun 2006
