Blue Monday

A shake-out-the-cobwebs kind of week?

Populating the front page took a while this morning, as a number of our favorite sources have been light on updates lately. java.sun.com doesn't have anything new since last Tuesday, and the Planet JDK aggregator only picked up a few things over the weekend.

Hard to say why things would be slow now... maybe the initial rush of returning from the holidays are over and everyone's into long development cycles to start the new year.

Fortunately, a number of project owners and others used the publicize your project link on the left nav of the front page to let us know what they're up to.

To wit: the ROME team wrote to let us know, "The ROME team is happy to announce the release of ROME 1.0RC2, ROME Fetcher 1.0RC2 and ROME Modules 0.3. Highlights include: ROME is now built using Maven 2, ROME jars are now available in the java.net Maven repository, more lenient handling of Number formats during parsing, and better date parsing for Atom dates. Complete change logs are available for ROME and the ROME Fetcher. Please see http://wiki.java.net/bin/view/Javawsxml/Rome for further information and downloads. "

We actually received a bunch of worthwhile project blurbs that we'll spread throughout the week. Plus, things will pick up Wednesday with the beginning of the Mobile, Media, and eMbedded Developer Days.


Also in Java Today, The Aquarium points out a New VisualVM 1.1 Release: "There is a New VisualVM 1.1 Release (Screencast). The Release Notes describe the new features but also notice the expanded Plugin API, the integration with Eclipse and IntelliJ, the support for IBM's JVM (via JMX), these new CLI commands, and its use of NB 6.5 RCP. VisualVM has been part of Sun's JDK since JDK 6 Update 7; together with the above changes, this makes it a good platform for writing performance analysis tools (e.g. see news)."

SDN published their Annual Developer Quiz during java.net's holiday hiatus, and it's well worth going back and checking out. The 10-question quiz covers topics previously featured on java.sun.com, including JavaFX Script, draggable applets, Greenfoot, LWUIT, real-time Java, and more.


This week's Spotlight is on the Mobile, Media, and eMbeded Developer Days. The conference begins Wednesday, and even if you're not attending, you can follow along by way of a live stream of the event. During the conference, there will be two streams -- one of the main auditorium and another of an upstairs session room -- and logged-in users will be able to interact with attendees and other viewers by means of ustream's chat features. More information about the live broadcast is available in the Developer Days wiki.


In today's Weblogs, Osvaldo Pinali Doederlein checks out the new language on the block for himself and asses its performance in
JavaFX: First programming (and performance) impressions. "I ported the JavaFX version of Bubblemark (a RIA benchmark) for JavaFX 1.0; tweaked it further, and evaluated its performance (with both good and bad findings)."

Tip-master Arun Gupta offers the latest in his long-running series,
TOTD #66: GlassFish Eclipse Plugin 1.0.16 - Install v3 Prelude from the IDE.
"GlassFish Plugins team released ver 1.0.16 of Eclipse plugin for GlassFish. The team has maintained pretty good cadence in terms of adding features and fixing bugs in the plugin (16 releases in approx as many months). However this particular version has an exciting feature. It allows GlassFish v3 Prelude to be installed from within the IDE itself."

Binod announces a MySQL-SailFin webinar. "On 21st January 2009, Alexander Yu and myself are giving a webinar on MySQL and SailFin."


In today's Forums, japotemp asks about load stats in
Glassfish cpu usage 100%, what is exactly measured. "At the moment I am generating traffic via an application on glassfish. With different monitoring tools I see different cpu usage.
visualvm 1.1 shows glassfish cpu usage of 100%, with top I see 35 %, with jconsole 35%. What does glassfish cpu usage exactly mean? The 100% is a bit worrying."

qu0ll asks
Is there a bug with clipping and affine transforms?
"Using Java 6 Update 11 (and probably earlier versions as well), I am finding that when rendering a shape and setting the clip region to that same shape, parts of the shape may "disappear" when certain scaling affine transforms are applied. For example, if I render a simple Rectangle2D.Float with the clip region set to that rectangle and then apply a series of scaling affine transforms where the aspect ratio is maintained, for some of those transforms one of the lines that make up the rectangle disappears, especially at smaller scale levels. It is not as simple as generalising that it only happens at smaller scale levels because it can appear, then disappear and then reappear as it is scaled down through a series of transforms. Is this the expected behaviour? If so, why? Is there any way around this?"

Pankaj Jairath provides some GlassFish set-up guidance in
Re: How to install load balancer using apache web server? "Yes, this component is OS dependent. Regarding Apache 2.2 installation instructions for Windows platform, please refer to - http://httpd.apache.org/docs/2.2/platform/windows.html. mod_jk is the plugin support from Apache itself; whereas HTTP LB from GlassFish is an advanced Load Balancing solution with features like load balancing policies (round-robin, weighted, user defined), application quiescing, instance quiescing, custom error pages, idempotent URLs, health check, etc. You can choose to use GlassFish HTTP LB as an advanced software solution for load balancing."
