Enterprise Streaming  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 java.io package. However, as Amir Shevat writes, the two are not mutually exclusive--you can write to JMS topics and queues with streams.   [ONJava.com]

Simplifying Java with Jakarta Commons Lang  Harshad Oak provides an overview of the Jakarta Commons Lang project and shows how the components in this project can simplify and accelerate development.  [dev2dev]

Managing Component Dependencies Using ClassLoaders  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.   [ONJava.com]

Regular Expressions in J2SE  Java applications that perform text searching and manipulation using String and StringTokenizer classes often result in complex code, leading to a maintenance nightmare. Another alternative is regular expressions. Hetal Shah explains how to implement regular expressions using the java.util.regex package, and how it can make your code easier to write and maintain.  [ONJava.com]

Form Your Own Design Pattern Study Group  Like most complex subjects, design patterns are best learned over a period of time, not in a few sittings. Eric Freeman and Elisabeth Freeman, coauthors of Head First Design Patterns, suggest one way to ease the learning curve (and have some fun along the way): form a study group, using their book. If you're ready to get your engineering team together, the Freemans get you started in this article with a plan to follow and chapter-by-chapter questions to help generate discussion.   [ONJava.com]
