Demonstrating a perhaps more aggressive path than anticipated, Sun Microsystems is set to announce the open-sourcing of the core Java platform within 30 to 60 days, Sun President and CEO Jonathan Schwartz said at the Oracle OpenWorld conference on Wednesday morning.

Mustang is galloping into town. Also known as Java SE 6, Sun's latest incarnation of the Java 2 platform should arrive in its first non-beta release by the time you read this article. Jeff Friesen shows you why the many new features (from console I/O and access permissions control methods, to the system tray API and table sorting and filtering) that you now get to play with make Mustang an interesting release.

This chapter covers the features of Java and .NET security that make interoperability easier. It also discusses different technologies (such as authentication in the Presentation tier) and the open standards (such as Web services security) where Java and .NET applications can interact. Finally, two interoperability strategies are discussed.

The JNode team announced the release of version 0.2.4 of the JNode.org operating system. JNode.org is an open source Java OS written in Java (with a very small assembler nano-kernel). This release features the first possibility of basic development under JNode. Screenshots are available, new features and improvements in this release listed are listed in the changelog.

"Groovy's concise syntax frees developers from typical Java constructs that are required for code compilation but don't facilitate expressing what a program is really trying to accomplish. In this revival of the Practically Groovy series, Groovy developer and guest columnist J. Scott Hickey walks you through a series of comparisons between normal Java code and the same Groovy code to show you how this exciting language frees you to focus on the important aspects of coding."

"This article gives you an overview of the architectural changes introduced in the latest Geronimo release, focusing on the new and innovative plug-in architecture. You'll also examine enhancements to the Web Console, including the memory utilization graph, thread pool statistics, the Java Message Service (JMS) resource wizard, and keystores. Finally, you'll explore changes to the Eclipse plug-in and get a look at Little-G."

Java SE 5 brought many needed enhancements to the Java language, none with more potential than annotations. Easily build and maintain validation logic in your Web apps using the Validator component of Hibernate Annotations.

Apache Geronimo is making news with its latest release, version 1.1. At its core is the Inversion Of Control model, which is also the core pattern for the Spring Framework. The Spring Framework was built on the principle that Java EE should be easier to use. This article provides information about the Spring Framework modules and how they relate to developing Java EE applications on Geronimo.

In this final installment on testing of the three part series, Brian Goetz examines another technique for smoking out bugs that violate design rules: aspects. The first two installments in this series, Part 1 covering testing in integrated frameworks and Part 2 on testing with leverage, show how static analysis tools like Find Bugs can provide greater leverage in managing software quality by focusing on entire categories of bugs rather than on specific bug instances.

Validation reports whether a document adheres to the rules specified by the schema. Different parsers and tools support different schema languages such as DTDs, the W3C XML Schema Language, RELAX NG, and Schematron. This is a good guide to learn about this XML validation API and how Java 5 adds a uniform validation Application Programming Interface (API) that can compare documents to schemas written in these and other languages.

NetBeans IDE provides a wide variety of tools to support Java application development, but it is the Source Editor where you will spend most of your time. Given that fact, a lot of attention has been put into features and subtle touches to make coding faster and more pleasurable. This chapter covers the ins and outs of the Source Editor.

This is the first release that has a full graphics 2D implemenation based on Cairo enabled by default. This enables the use of applications like JEdit, FlickrBackup and JFreeChart out of the box. See Screenshots of CairoGraphics2D in action. Also new in this release is the inclusion of an applet viewer and plugin that can be embedded in webbrowsers or other applications. It works on any platform supported by the various runtimes based on GNU Classpath, including 64 bit architectures. Lots more improvements, like better gnome integration, are mentioned in the release announcement.

Eclipse isn't a single monolithic program, but rather a small kernel called a plug-in loader surrounded by hundreds (and potentially thousands) of plug-ins. In this chapter Eric Clayberg and Dan Rubel give you a more in-depth understanding of Eclipse and its structure in relation to creating plug-ins.

"The Java community has used JavaServer Pages technology through most of the last decade, but signs of rust are starting to show. Longstanding conventions inhibit Java programmers from using Java code within Web pages now, and extending even simple components is a chore. Frameworks that take Java Web development beyond JSP programming have emerged, but they fall short of dynamic languages' capabilities. This article shows you Ruby's Web page development strategy and touches on Seaside's radical approach."
