OpenJDK Community Innovators Challenge announced

Yesterday, we linked to the Winners of the GlassFish Awards Program, and today, we move on to OpenJDK.

Sun has announced the winners of the OpenJDK Community Innovators' Challenge, part of the Open Source Community Innovation Awards Program to fund open-source communities. Clemens Eisserer picked up the Gold award for the Implement XRender pipeline for Java2D project, Neal Gafter took Silver for Closures for Java, and two Bronze awards were handed out: Stephen Colebourne and Michael Nascimento Santos for Provide date and time library from JSR-310 and Roman Kennke and Mario Torre for Portable GUI backends. Dalibor Topic has posted a set of audio interviews with all the winners in Ogg Vorbis format.

Congratulations to all the winners. Tomorrow, we'll look at the NetBeans community awards winners.


Also in Java Today,

The Aquarium reports that the EJB 3.1 Public Draft is now available. "The JSR-318 EG has released the Public Draft of EJB 3.1 (Download). Ken
(the EG lead) is soliciting feedback by email or directly in his blog. Ken will continue to providing highlights of the new features through his blog, a practice he started after the first Early Draft
([1], [ title="Optional Local Business Interfaces">2], [3], [ title="Preview of Features">4]). His latest entry is Guide to the EJB 3.1 Public Draft." They also remind us that "Ken will present on this topic today (Thursday) at 11:15 am Pacific Time in the GlassFish Online Webinar."

NetBeans developers are a diverse bunch of individuals, working in multiple programming languages and speaking in even many more tongues. Where and how do these users, from all corners of the globe, exchange programming tips and offer each other support? Find out in the coming weeks as we spotlight some of the popular foreign language portals, forums, blogs and mailing lists devoted to or related to the use of the NetBeans IDE and NetBeans Platform. This week, we compile a list of sites favored by Chinese-speaking developers.


In today's Weblogs, Claudio Miranda looks at how to do a Heap dump on Linux 64 bits. "With the current stable JDK 6u7 it is not possible to generate heap dump on linux 64 bits. Looks like it was a bug, fixed on JDK 6 u10 RC. Read on for more details."

Jim Driscoll looks into Dependency Managment with Glassfish Updatecenter and IPS. "In a previous blog, I wrote about how to create a basic updatecenter module for Glassfish v3. Since I've just finished working on something a touch more complex, this time I'll cover how the Update Center's IPS structure handles dependency managment, including a fairly odd corner case that I had to recently deal with."

Finally, Santiago Pericas-Geertsen continues his Mobile Enterprise Platform connector series in
Developing MEP Connectors - Part III. "In the two installments of this series we've looked at the architecture of a MEP connector, discussed the main abstractions of the ECBO (Enterprise Connector Business Object) API and showed an example of a MusicAlbum business object. In this third part, we'll focus on the MusicAlbumProvider class which is needed to complete the implementation of the connector to access music albums from a JDBC database."


In today's Forums, abhatnagar192006 asks for clarifications regarding a
Conceptual insight regarding JAVA FX. "JAVA FX, i understand is a rich user interface enabling technology. I have heard that it can be used for making a GUI for desktops as well as embedded devices such as mobile phones and set top boxes. My doubt here was, that embedded devices would need a KVM / CVM for hosting a user interface application. While a normal desktop application needs a JVM. Does JAVA FX SDK come in 2 variants..one for desktops and one for embedded devices?"

sjoedzj's
binding problem and hyperlink question starts with a question about binding as applied to the size of dynamic JavaFX components. "The second question might be a simpler one. How can I create a hyperlink in javafx. I have this widget and I want to add some links to it that open a browser and go to the address specified. Can anyone help me on these problems?"

Finally, defrit wonders if it's possible to do
JSR-172 complex parameters. "I just tried using an object of a self-developed class as a web service parameter. The content didn't reach its target. I didn't get any error message tho. It only worked out with primitive data types like int, float etc. Am i right to assume that JSR172 doesn't support complex parameters? If so, what additional software could i use to solve this (i've already read of ksoap)."
