Scheduling Jobs in a Java Web Application
By Chris Hardin
Web application frameworks are built to service requests when they come in, typically from web users. This seems fine, but what if you need to execute code at specific times (for example, to generate reports in the middle of the night when CPU use is low)? Quartz provides best-of-breed Java scheduling functionality, and in this article, Chris Hardin shows how to get Struts to load up Quartz and your scheduled work. Mar. 1, 2006

Asynchronous Messaging Made Easy With Spring JMS
By Srini Penchikala
Java Messaging Service (JMS) requires a lot of work to set up sessions and manage messages, work that can distract you from your application-specific logic. The Spring framework's SpringJMS offers a simpler solution that keeps the JMS administration out of your face. Srini Penchikala takes a look. Feb. 22, 2006

J2EE Without the Application Server
By Guy Pardon
J2EE apps sound big because they usually are big, running on big enterprise-class application servers--servers that often provide a lot of functionality that you don't really want or need. In this article, Guy Pardon advocates a mix-and-match approach to combining Spring with best-of-breed persistence and transaction frameworks to build enterprise applications without a traditional J2EE app server. Feb. 8, 2006

The Java Podcasters, Part 1
By Chris Adamson
As podcasting takes off, a number of podcasts specifically tailored to the Java developer have become available.

In this article, we interview the voices behind the Swampcast and Java Posse podcasts. Jan. 25, 2006

Spring: Integrating iBATIS

iBATIS is one of the object-relational (OR) frameworks embraced by the Spring framework, and it's an ideal choice for those seeking a middle ground between full-blown OR and hand-written JDBC.

Using Lucene to Search Java Source Code
By Renuka Sindhgatta
Most uses of the Java-based Lucene search engine are for searching typical text documents. But what if you want to search Java code itself?

Using Dependency Injection in Java EE 5.0
By Debu Panda
Dependency injection, also known as inversion of control, is a programming technique being adopted by many programmers and frameworks, including the popular Spring framework.

Hibernate Class Generation Using hbm2java
By John Ferguson Smart
Hibernate uses mapping files to express the mapping of Java classes to database tables. In a complex project, keeping mappings in sync with your Java code can be burdensome and error-prone. Fortunately, the hbm2java tool can automate this by generating POJO classes from the mapping files. John Ferguson Smart shows how to use hbm2java with Ant and Maven, and how to customize the behavior of the generated classes. Dec. 14, 2005

Lightweight R/O Mapping
By Norbert Ehreke
O/R frameworks map Java classes to database tables and SQL code. While popular, this approach is unpopular among DBAs, with the database at the mercy of an external tool. Another approach is to go the other direction: write tables and stored procedures and generate Java classes from that. Norbert Ehreke introduces Amber, a framework that embodies this approach. Dec. 7, 2005

Hacking Swing: Translucent Windows
By Chris Adamson, Joshua Marinacci
All Java windows are absolutely rectangular, so you can forget about creating a nice Winamp-like window for your Swing app, right? Wrong. In this excerpt from Swing Hacks, authors Joshua Marinacci and Chris Adamson show how you can use some imaging trickery to create arbitrarily shaped windows with Swing. Nov. 9, 2005
