As I wrote yesterday, this weekend java.net is transitioning to a new infrastructure. All content that has been hosted on O'Reilly servers is being migrated to new systems. It's a big task, as you might imagine, given that java.net has been around for more than six years.

The transition begins today at 5:00 PM U.S. Pacific time (which I believe is Midnight GMT, August 22). The site will will be unavailable until Monday morning U.S. Pacific time (early to mid afternoon GMT, August 24).

Several people beside me have posted information about the transition, including:

• Sonya Barry: Big changes under the hood for java.net
• Paul Sterk: More info on CMS migration this weekend
• Felipe Gaucho: Have a nice weekend java.net

This week's poll on the Java Store and Java Warehouse is closed. I'll write about the results of the poll, and create a new poll using our new platform, next week.

Now, I'm off to do more testing on the new system!

In Java Today, Frank Kieviet announces OpenESB community partner releases the first commercially supported OpenESB component: "Many of the components in OpenESB were developed by Sun, and all of the components in the GlassFish ESB distribution are commercially supported by Sun. Now, for the first time, and hopefully the first of many to come, it is an OpenESB community partner that has taken a component through the OpenESB release process, providing commercial support on it..."

Danny Coward writes about a New API for Constraint Programming: "Constraint programming is a kind of declarative programming. Specifically, where you say what conditions constitute the solution of problem, rather than the laying out steps or algorithms by which you get to it. Deng Xiaoping had a saying for it. A bit like assessing weather conditions for sailing, or evaluating economic indicators when deciding central bank policy, these conditions come in the form of restrictions on the interrelationships of a carefully selected set of variables which model the computing problem..."

Adam Bien posted We Are Done with Layers - Now Start with Plugins: 'With Java EE 5 the architectural style changed drastically. Superfluous layers and indirections are an exception, rather than the mainstream. Even hard core ivory tower architects accepted, that with EJB 3 and JPA there is no more need for additional adapters and encapsulations. But: even in small, "situational" applications there is desire to introduce plugins and modules. The question: "Why you need it?" and "What problem are you solving with that?" is rarely answered...'

In today's Weblogs, Vivek Pandey writes about Reviving Project WOM - WSDL Object Model: "Sometime back I started a project - WOM, short for WSDL Object Model. The idea was to come up with a library that provides efficient parsing and provides a WSDL Object Model that can be used to inspect, traverse/navigate and will be useful for IDEs such as NetBeans and also WSDL 2 Java generators, such as Metro wsimport."

Felipe Gaucho posted Have a nice weekend java.net: "java.net is evolving to a more sophisticated and modern infra-structure, so I hope to see you all on Monday :)"

And Arun Gupta provides TOTD #95: EJB 3.1 + Java Server Faces 2.0 + JPA 2.0 web application - Getting Started with Java EE 6 using NetBeans 6.8 M1 & GlassFish v3: "TOTD #93 showed how to get started with Java EE 6 using NetBeans 6.8 M1 and GlassFish v3 by building a simple Servlet 3.0 + JPA 2.0 web application. TOTD #94 built upon it by using Java Server Faces 2 instead of Servlet 3.0 for displaying the results. However..."

In the Forums, Rochelle Raccah announces a New version of Eclipse plugin for glassfish published: "Version 1.0.31 of the GlassFish plugin for eclipse was published today. Here is a link to the release notes which lists the bug fixes that are included: https://ajax.dev.java.net/eclipse/releasenotes.html In particular, we've added a bugfix in the monitoring support and some more SailFin features in this release. As with previous versions, you can download it from within Eclipse using the Download additional server adapters link on the New Server Wizard..."

Paul Sterk posts More info on CMS migration this weekend: "All, More details on the CMS migration this weekend: Everything on java.net that is *not* on the dev.java.net domain will be migrated over to new CMS servers based on Drupal. That includes all of our editorial history, blogs, Jive, Jive-mailings list bridge, Twiki, project and community catalogs, and any other (mostly) html or csp pages that O'Reilly has been hosting for us. At the same time, a new layer will streamline and partially automate the process of approving and promoting projects..."

And Sean Comerford asks for Glassfish cluster limits / best practices?: "Are there any best practices / hard limits around the # of: * node agents; * instances; * configurations; * etc that a given DAS domain can control / support? ..."

The current Spotlight is a video, Java Warehouse - Part 1 of 3 - How to Submit an Application - Registration: "Learn how to submit applications to the Java Warehouse. In this first segment Bernard Traversat, Director of Java Store Engineering, shows how easy it is for developers to register for the Java Warehouse Developer Portal."

The next java.net Poll will be posted next week, after the java.net infrastructure transition has occurred.

Our Feature Articles include Jeff Friesen's article Introducing Custom Paints to JavaFX, which shows how you can leverage undocumented JavaFX capabilities to support custom paints in JavaFX Version 1.2. We're also featuring Biswajit Sarkar's Using the Payment API for Microcredit and Other Applications, which describes how to apply the Payment API (JSR 229) in JavaME applications.
