In this second article of his four-part "JSF for nonbelievers" series, Rick Hightower introduces the major phases of the JSF request processing lifecycle. Using a sample application, Rick walks you through the five phases of a request process. Along the way, he shows you how to combine JSF with JavaScript for immediate event handling and completes your introduction to the JSF component model, with a first look at many of the components that ship with JSF.
JUnit lets you test software code units by making assertions that the intended requirements are met, but these assertions are limited to primitive operations. IBM Software Engineer Tony Morris fills the gap by introducing Assertion Extensions for JUnit, which provides a set of complexassertions that execute within the JUnit framework. Follow along as the author shows you how using this new package from alphaWorks can increase the reliability and robustness of your Java software.
A comprehensive unit-test suite is a necessity for a robust program. But how can you be sure that your test suite is testing everything it should? Jester, Ivan Moores JUnit test tester, excels at finding test-suite problems and provides unique insights into the structure of a code base. Elliotte Rusty Harold introduces Jester and shows how to use it for best results.
You may know that Eclipse is a framework meant for building other tools. You may also know that you can build your own plug-ins for Eclipse. But did you know that Eclipse comes with seven different plug-in templates to get you started? This tutorial starts you off with a start-to-finish look at building a plug-in using the "Hello, World" template, and then introduces you to the other templates, such as "Plug-in with an editor" and "Plug-in with perspective extensions".
Software engineers are notoriously obsessed, sometimes excessively, with performance. While sometimes performance is the most important requirement in a software project, as it might be when developing protocol routing software for a high-speed switch, most of the time performance needs to be balanced against other requirements, such as functionality, reliability, maintainability, extensibility, time to market, and other business and engineering considerations. In this months "Java theory and practice," columnist Brian Goetz explores why it is so much harder to measure the performance of Java language constructs than it looks.
Spring is a layered Open Source Java/J2EE application framework. The three articles in this series assist developers on how to use the Spring framework and explain the principles behind inversion of control design strategy used by the Spring framework. This series will assist developers and architects on how to build powerful J2EE-based open source frameworks. Part 1 analyses and introduces the Framework, its features and principles.
java.net is no longer posting a separate "news" section, which previously had been used to link to off-site news stories, largely version updates of open-source and commercial software. If youre looking for a similar service, Steve Mallett collects many Java-related news and blog feeds at the http://www.planetjava.org/ site. If you are receiving this message via an RSS feed, you should unsubscribe to the feed.
Configuration management has proven to be a valuable tool in coordinating and tracking changes within a development environment. It is most often applied to such program components as program source code and dependent program products. In this article, youll learn how to apply that configuration management to the database environment plus get some suggestions on how to track and record database versions and change information.
While the constructs of multithreaded application programming in the Java language arent difficult to learn, many developers struggle with applying them correctly. As a result, multithreaded programs are often far more prone to subtle errors than we would like them to be, leading some developers to avoid them at all costs, even when concurrency and parallelism would clearly yield the most elegant design. In this three-part article, Senior Technical Architect Abhijit Belapurkar sets you on the path to overcoming your fear of multithreaded programming for once and for all, starting here with an overview of the most common issues involved: race hazards, deadlocks, livelocks, resource starvation, and more.
IBM is launching a revamped developerWorks Open source zone, which will deliver more articles, resources, tools, and tutorials that support major industry open source initiatives, including Linuxâ„¢, Apache, Derby, Globus, and Eclipse. Learn how you can benefit.
froglogic GmbH has announced the initial public release of Squish/Java. They write in, "Squish/Java is a new edition of the powerful, platform-independent testing framework Squish. This new edition features the automatic creation and execution of tests for Java Swing, AWT, SWT and RCP/Eclipse applications."
Hibernates formula element has been limited in previous versions of the popular object-relational mapping framework, but in Hibernate 3, your formulas can be used in many new ways that will simplify and empower your programming. Dai Yifan shows you whats new.
This tutorial shows how to build a Web service using the Eclipse Web Tools Platform. The Web service interacts with a Cloudscape (Apache Derby) database and is deployed to Apache Tomcat.
The GeoServer project has announced the release of version 1.4.0. "The big push of this release is the transition of GeoServers architecture to a more modular, programmer friendly environment based on Spring. From the user perspective there are many improvements for scalability and stability, along with many little fixes so that everything just works. There is a new German translation of the Web admin tool, and improvements for output of Shapefiles, GML, PDFs, SVG, and Google Earth KML, to put control of the output in the hands of the user."
The FindBugs project has announced the release of version 1.1.2-rc6. "Fixed some small bugs in the eclipse plugin; some small changes in core findbugs, having to do with uniqueIds and instanceHashes for bugs. Shouldnt effect anything, but testing would be appreciated."
BFO breaks new ground with its PDF Library now able to Pre-flight PDFs to the PDF/X standard, providing the ability to create, verify and repair documents to the PDF/X-1a:2001 and 2003 standards.
Joshua Marinacci, coauthor of Swing Hacks, shows you six undocumented features, classes, and properties that let you hack into Swing. From how to hide a frame from the Windows task bar to how to make Mac OS X windows truly transparent, these undocumented hacks can add a level of polish that will make your apps stand out from the rest.
During the GlobusWORLD conference in Boston, developerWorks, together with writer Hal Hensley, had an opportunity to sit down with Ken King, vice president of IBM Grid computing. We engaged in a wide-ranging discussion regarding the state of grid computing and IBMs current activities, positions, and ideas on this front.
The Jess rules engine project has announced the release of version 7.0p1. "Several minor bugs from the 7.0 release arefixed. Formatting and syntax coloring in the JessDE are no longer confused by multiline strings and comments. The JessDE contains a few new selection and formatting commands."
The Java 3D team has announced the open source release of the j3d-core and vecmath subprojects on java.net under the GPLv2 license with the CLASSPATH exception. This applies to all source code in the javax.media.j3d and javax.vecmath packages. Read the LICENSE.txt and README-FIRST.txtfiles in the top directory of each projects source code repository for details on what the license allows you to do.You may notice that the web page and various README files now refer to the "3D Graphics API for the Java Platform" in many places. This is the official name for the open source version of the Java 3D API. Other than the name, there are no differences (and, in fact, we will build the binary version of Java 3D 1.5.2 from the same sources).The name change was done for the same reason that OpenJDK chose a different name than "Java" for their release: namely, Java 3D is a trademark of Sun Microsystems, and we want to make it clear that: A) we are not giving away rights to use that name, and B) the binaries built from these (possibly modified) sources are not "Java 3D" from Sun.Subject to the terms of the GPLv2 license, you may modify the j3d-core or vecmath sources, but you may not call it "Java 3D".
Sun Microsystems has finalized JSR 222 - Java Architecture for XML Binding (JAXB) 2.0. "JAXB 2.0 is a follow-on to JSR 31 Java XML Data Binding Specification buildingupon the architecture introduced in JAXB 1.0 JAXB 1.0 lowered the barrier for developers manipulating XML content from Java TM applications."
