What is Java Content Repository
You might have heard of JSR-170, but what is a content repository, and what can you do with it? Well, do you want to manage documents with versioning, search, access control, and more? Content repositories offer these features, and JSR-170 codifies them into a single API. Sunil Patil shows how to use the reference implementation--Apache Jackrabbit--to create a blogging application.
Tapestry: A Component-Centric Framework
Tapestry offers an open source framework for rapid development of web applications using Java. It offers high performance, good code re-use, line-precise error reporting, and more. Hemangini Kappla offers an introduction to this widely used framework.
Eclipse RCP: A Platform for Building Platforms
Where do you start when building a Java desktop application? All Java gives you by default is public static void main (String); it's up to you from there. Eclipse's Rich Client Platform (RCP) offers a tested design, commonly-needed widgets, a standardized component model, pervasive extensibility, and more. Wayne Beaton has an introduction to get you up to speed with RCP-based development.
Ant 1.7: Using Antlibs
Most Java developers use Ant to do builds and are familiar with its core tasks. But Ant's tasks tend toward an undesirable coupling: everything important had to be a core task because it was hard to distribute new plug-in tasks. Fortunately, Ant 1.7's new antlibs feature makes it much easier to distribute and use new Ant tasks. In this article, Kev Jackson shows you how to use, write, bundle, and test antlibs.
If you have a need for generating or displaying reports, you may want to have a word with BIRT. The Business Intelligence and Reporting Tools project is an open source Eclipse effort to enable the creation and deployment of complex reports. Jason Weathersby shows you how to grind out reports and display them in web applications and RCP-based desktop apps.
What Is Geronimo?

Outsourcing Java SE
Many eyes are on Sun, awaiting the promised eventual open-sourcing of its Java SE implementation. But Daniel Steinberg has another idea: instead of open-sourcing Java, Sun should outsource it, so that it can be developed by parties more attuned to the needs and opportunities of cross-platform development.
What Is Jetty
Of course Tomcat is the first Java application server you think of, but is it the right tool for every job? The open source Jetty serves up JSPs and servlets in just a fraction of the memory needed by other app servers and is designed for easy embedding in other applications and non-traditional Java environments. Ethan McCallum takes a look at the big things in this small package.
Telling Stories at JavaOne
JavaOne 2006 left attendees with an incomplete answer to the big question: will Sun open source Java? The answer was better than a definite maybe, but not by much. Daniel Steinberg looks back at the conference, its mixed message, and its many successes outside of the general sessions.
Using Lucene to Search Java Source Code
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? Renuka Sindhgatta argues that this would be a boon for finding reusable code, and shows how to adapt Lucene to parse Java code for maximum searchability.
Give Your Business Logic a Framework with Drools
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.
Upload Files with JSF and MyFaces
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.
An Ant Modular Build Environment for Enterprise Applications
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.

Introducing JBoss Remoting
With JBoss World 2005 a week away, JBoss has introduced a new remoting framework. Before you say "another one?" John Mazzitelli hopes you'll take a look at JBoss Remoting, which rids you of RMI-style skeletons and stubs, and offers flexibility and extensibility on both the client and server sides.
Mock Objects in Unit Tests
Unit testing your code against a service or process that's either too expensive (commercial databases) or just not done yet is something you can deal with by simulating the other piece with a mock object. EasyMock can suffice in some cases, but it can only create mock objects for interfaces. Mocquer, based on the Dunamis project, can create mocks for classes, too. Lu Jian shows how it works.
XML Messaging Using JBoss
Simple communication in an enterprise system is possible through various schemes, but not all of them answer the question of coordination. Benoit Aumars presents a hypothetical case study that shows how generating and sharing information in XML is made easier with Java Messaging Service (JMS) and Java Management Extensions (JMX).
What's So Java About Sun's Linux Desktop?

Enums in Java (One More Time)
Depending on who you ask, the lack of built-in enum support in Java is either a travesty or no big deal. They're convenient in some cases, and are often requested for future versions of Java. John I. Moore, Jr. explores the alternatives for emulating enums in core Java and presents the mini-language jEnum as proof-of-concept.

The goal of the Jakarta Project is to provide commercial-quality server solutions based on the Java Platform that are developed in an open and cooperative fashion. Jakarta is the "overall" project for many subprojects. For example, Tomcat is the Servlet+JSP Engine which is a subproject of the Jakarta Project. Many people confuse Jakarta and Tomcat together even though the reality is that Jakarta is essentially just this website and Tomcat is a product on this website. You can get information about each of the projects by looking at the left side navigation under the "SubProjects" headings.

The JavaLobby Foundation Applications (JFA) is an effort to produce high quality, open source, pure java applications in an attempt to demonstrate the power of java. JFA software is released under the JFA License which allows completely unencumbered redistribution and reuse of the code. Applications such as an Application Toolbar, Spreadsheet, Word Processor, Email Client, Zip File Utility, and more have already been started, and some are available for download now. A first class icon collection has already been created and is being expanded every day. Many developers have already volunteered to create these applications, but more are still needed. Besides programmers, the JFA project also needs people to write documentation, create graphics to accompany the programs, and to organize other volunteers. [Source: JFA]

Others could soon be announced and available. [Source: Sun]
The Universal Description, Discovery and Integration (UDDI) standard (registry) is a sweeping industry initiative. The Standard creates a platform-independent, open framework for describing services, discovering businesses, and integrating business services using the Internet. UDDI is the first cross-industry effort driven by platform and software providers, marketplace operators and e-business leaders. These technology and business pioneers are acting as the initial catalysts to quickly develop the UDDI standard. The UDDI standard takes advantage of WorldWide Web Consortium (W3C) and Internet Engineering Task Force (IETF) standards such as Extensible Markup Languare (XML), and HTTP and Domain Name System (DNS) protocols. Additionally, cross platform programming features are addressed by adopting early versions of the proposed Simple Object Access Protocol (SOAP) messaging specifications found at the W3C Web site. The UDDI standard is the building block that will enable businesses to quickly, easily and dynamically find and transact with one another using their preferred applications. [Source: UDDI]
