Give Your Business Logic a Framework with Drools
By Paul Browne
It's almost too easy to express your business logic as a spaghetti-code fiasco. The result is hard to test, hard to maintain, and hard to update. Rule engines offer an alternative: express your business logic as rules, outside of your Java code, in a format even the business side of the office can understand. Paul Browne uses the open source Drools framework to introduce the idea. Aug. 3, 2005

Bean-Managed Transaction Suspension in J2EE
By Dmitri Maximovich
Container-managed transactions seem more capable than bean-managed transactions in the EJB spec, with the latter unable to, for example, suspend and resume transactions. But what looks like a limitation isn't necessarily so, according to Dmitry Maximovich, who shows you how to get to the underlying TransactionManager, making BMT as powerful as CMT. Jul. 20, 2005

Upload Files with JSF and MyFaces
By Andrei Cioroianu
Want to support uploading of files from the user's browser to your web application? You could parse the multipart form data yourself--or you could let Java do it for you. JSF doesn't support this out of the box, but, as Andrei Cioroianu shows, several JSF-based frameworks do. Jul. 13, 2005

Taking JUnit Out of the Box
By Amir Shevat
JUnit is practically ubiquitous among Java developers as a way to test code, but it's somewhat limited by the fact that it's only meant to run in one JVM on one box, hampering its usefulness when developing distributed applications. In this article, Amir Shevat shows how the open source JUnit extension Pisces helps JUnit overcome this limitation. Jul. 13, 2005

Generics in J2SE 5.0

POJO Application Frameworks: Spring Vs. EJB 3.0
By Michael Juntao Yuan
Spring and EJB 3.0 are both reactions, in their own ways, to the complexity of EJB 2.1 and the complaints piled upon it. Both support developing with Plain Old Java Objects (POJOs) and give the framework responsibility for handling transactions, security, persistence, etc. But the two use substantially different approaches. In this article, Michael Yuan puts the two frameworks up against one another to see how they stack up. Jun. 29, 2005

An Ant Modular Build Environment for Enterprise Applications
By Les A. Hazlewood
Most Java developers already use Ant for their builds, but are you getting everything you could out of this tool? With a complex enterprise application, in which classes may be used in several tiers, it's important to control where the code lives and how it gets built, so you can build .jars with just the code needed for each tier. Les Hazlewood shows how this approach leads to faster builds and downloads, and even catches errant dependencies. Jun. 22, 2005

Enterprise Streaming
By Amir Shevat
The Java Message Service is a lynchpin of J2EE, but is in some ways more difficult and less flexible than more basic forms of communication, like the stream model of the package. However, as Amir Shevat writes, the two are not mutually exclusive--you can write to JMS topics and queues with streams. Apr. 20, 2005

Managing Component Dependencies Using ClassLoaders
By Don Schwarz
Use of the Class-Path entry within a JAR file's manifest can help you manage external dependencies--to a point. Once you start using multiple JARs that need incompatible versions of external JARs, problems quickly ensue. As Don Schwarz shows, you can get out of this problem by using your own class loader to manage the dependencies. Apr. 13, 2005

Form Your Own Design Pattern Study Group
By Elisabeth Robson, Eric Freeman
