Time again to cast ballots
As promised yesterday, the Election Ballot is now available for registered Java Community Process members to vote in the JCP 2008 Election . Candidates for the SE/EE EC are Intel Corp., Werner Kiel, Matthew McCullough, and Shashank Tiwari. On the ME EC, the candidates are Aplix Corporation, Sean Sheedy, and Sony Ericsson Mobile Communications AB.
It's interesting to see so many individuals running in this year's elections: 3 out of 4 candidates for the SE/EE seat, and 1 of 3 for the ME seats. There's been a trend towards corporate and organizational membership on the EC's, so we'll see if this year's results turn that trend or maintain it.
Balloting ends November 17.
Also in Java Today ,
the latest edition, issue 183 , of the JavaTools Community Newsletter is out, with tool-related news from around the web, updates from the Dead Code Detector and JFeature tools, a list of new projects in the community, a graduation from the incubator (Maven-incremental-build ), and a Tool Tip on using Google to find code.
In order to celebrate the release of NetBeans 6.5 the NetBeans User Group Munich (NUGM) will hold the first Munich NetBeans Demo Camp on November 18th. "The camp will focus on NetBeans as a Rich Client Platform. Companies and individuals are invited to showcase their products and share their experience. As special guests members of the NetBeans Dream Team and the NetBeans Team in Prague will show the latest platform features in NetBeans 6.5. Join your peers for an event packed with information and cool demos." Invited speakers include Geertjan Wielenga, Anton Epple, Aljoscha Rittner, Tanja Drüke, and Sven Reimers.
Today's Weblogs start with RÃ©mi Forax declaring it's time to accept and embrace Generics. In Raw type, rare type and preparing the future , he writes, "we live in a post-generics world, recently, October 30th, 2008, J2SE 1.4.2 retires has reach its End Of Service Life . I think it's a coincidence but Maurizio Cimadamore decide to introduce a long requested feature in javac , emit a warning for all usages of raw types."
Jim Driscoll offers
A simple Ajax JSF 2.0 example .
"Another new feature of JSF 2.0 is integrated Ajax support. Here's one fairly simple example of that feature in action."
Finally, Arun Gupta offers some guidance for
Getting Started with Edge Rails (2.2) using JRuby and GlassFish . "This blog shows how to get started with Edge Rails (2.2, almost there) using JRuby. The blog uses JRuby 1.1.5 and GlassFish v3 Prelude b28c to deploy a simple Rails app."
In today's Forums ,
Sebastian Hofmann proposes managing a EJB-JMX combination in
Manage a TimerBean using JMX - general question . "I am to develop an application running an import job executed by an EJB using the timer service. I need some properties for this job and want to make the execution interval configurable by the administrator. Also I figured out that in case of an exception occurring while execution the timer will be suspended. So I need a way to restart the timer. I think JMX might be the right solution."
Jon Miller wants to know the
JAX-WS 2.2 release date . "Does anyone know when JAX-WS 2.2 is due for release? Does anyone know when it will be possible to mark web service method parameters as nillable?"
wonders if you really
can't deploy two set of JPAs into the glassfish?
"I have a standalone java SE netbeans project which uses JPA. And I also have a java EE web project which needs to call the java se project. the java ee web project itself uses JPA. But I found I can't deploy two set of JPAs into the glassfish. How to solve this problem?"
snewbold reports a suspected
File Descriptor Leak . "We have an EJB application running inside a glassfish app server (9.1_02, build b04-fcs) on linux CentOS (5.2). The application consists of a number of stateless session beans and entity beans. Persistence and DB connections are handled via Oracle toplink. The stateless session beans are accessed via remote clients running a swing desktop GUI application (non ACC client). We have noticed that the glassfish app server process "leaks" file descriptors when the system is being used (i.e., daytime hours). When the app server first starts, it has 250-300 fd's and after about 7 days up time we get up over 1000 fd's. The number of fd's oscillate during light usage times but then climbs dramatically during periods of higher usage."
