What Would You Say

Busy day in the forums

We used to run two items a day from the forums on the front page, and last year, I decided to experiment with putting three up there, to see if it improved traffic or the variety of posts. Now that's a very subjective topic, but I did think that after a while, it got easier to find three good posts to use, messages that had interesting short excerpts, weren't completely dependent on their thread for context, enticed the casual reader to come by and read more, etc. Maybe that was the messages getting better, or me learning how to find (or edit) messages to make them work, I don't know...

But today, I couldn't cut down to three messages. So I posted four. And there was a fifth one, about uploading "cells" to Project Wonderland, that nearly made the cut.

Our current internal plans call for us to take a long hard look at the forums in the coming months and rework the various categories to best suit current interests: we should really embrace new topics like JavaFX and retire forums that have served their purpose, like "The Big Question", which preceded the GPL'ing of Sun's JDK. Still, even in their current form, the forums are host to a remarkable variety and genuine depth of discussion. We're glad you find them useful, and hope you'll tell us how they can be improved.

We'll start today's Forums section with some green fields design work in the Project Wonderland forum. In

Re: Some thoughts about the modules design, kaplanj writes,
"Java Web Start is good, but it has some downsides. Right now, both the client and server must be restarted to recognize a new cell type. Also, the build scripts need to be updated to only rebuild jar files that have changed -- right now they rebuild all jar files. A Servlet should also be written to use the packed jar files. If you are interested in developing a more complete module system to allow dynamic loading, we would welcome the contribution. I would love to see a design document we can all comment on (like Jordan did with WFS). To help get started, I have also included an email I wrote to the team a while back on the subject of modules."

V B Kumar Jayanti explains where XWSS has gone in
Re: cannot find xwss sample download.
"The main page for XWSS is now and it ships in Project WSIT/Metro ( and Metro is in turn a part of GlassFish. So yes you can get samples of XWSS 2.0 style and XWSS 3.0 style security. XWSS 3.0 (which is what is used WSIT/Metro) makes use of WS-SecurityPolicy to specify the security policies of a service inside the WSDL. Please post XWSS related questions to You can quickly create Security Applications by making use of NetBeans (with WSIT Plugin) and GlassFish."

brunogh has some guidance for getting started with Bluetooth development in NetBeans, in the message
Re: bluetooth jsr82.
"After you create a mobile project you can check Bluetooth availability by clicking with the right button in the project and then Properties->Platform, then select the Java Apis for Bluetooth Wireless Technology optional package (by default is selected). After that, you can run two instances of the project and emulate Bluetooth communication Try to run BluetoothDemo available in ME Application Developers Demo Box."

Finally, in Re: [JAI] JAI Success Stories, Brian Burkhalter reveals how to get listed on the JAI home page. "These success stories may be supplied directly to me. Assuming that the project is interesting then there is a good chance that this will be posted. The verbiage should included something about what JAI contributed and one or more images should accompany the text. A perusal of existing pages should provide a good idea of what is required."

Our latest Java Mobility Podcast is
Java Mobile Podcast 21: Wireless Toolkit.
The Sun Java Wireless Toolkit for CLDC and CDC is a state-of-the-art toolbox for developing wireless applications that are based on Java ME's Connected Limited Device Configuration (CLDC) and Connected Device Configuration (CDC), and designed to run on cell phones, mainstream personal digital assistants, and other small mobile devices. The toolkit includes the emulation environments, performance optimization and tuning features, documentation, and examples that developers need to bring efficient and successful wireless applications to market quickly.

Rémi Forax shows off Mixing property language support and bean bindings in today's Weblogs. "Recently, Shannon posted version 1.0 of beanbindings. Even if this version is not ready for production use, it is stable enough to create a small demo mixing property language support and beanbindings."

Felipe Gaucho makes note of a program to get students unemployed programmers certified, in
CEJUG Certified: free vouchers of Sun Certification Program.
"A JUG created a program where local companies provide reimbursement of vouchers to members who succeed in the Sun Certification Program exams."

Finally, Joerg Plewe introduces
A simple physics/dynamics stack.
"Are you doing engineering using Java? Or even science? Than you sometimes might need to calculate how objects move under the impression of forces and torques. The following might be for you then..."

In Java Today,
the next GlassFish Day is Wednesday this coming week in Milan. Of course we'll discuss the recent GlassFish v2 release and v3 plans, but we'll also cover Portal, OpenESB, Jersey/JAX-RS, OpenMQ and Metro. This free event is part of the greater Sun TechDays event in Italy [Registration] - Monday/Tuesday in Rome, Wednesday through Friday in Milan. Arun has already blogged about jMaki and Web Services sessions. There will also be "Java EE , GlassFish and Their Future" presentations in both places. Check the agenda.

A new SDN article by Greg Murray and Ed Ort looks at Restricting Access to Ajax Services in Java EE. "This article highlights some techniques for restricting access to Ajax-based services. It then focuses on using URL-based API keys, which gives you fine-grained protection and allows you to track, meter, and restrict usage of a service."
