Stay Up Late

Posted by editor on February 13, 2006 at 8:08 AM PST


Step up, put up, shut up... or wake up?

Your editor's three-year-old decided to be up from 2 to 5 this morning, and as a result, I'm barely thinking straight. So let's let the front page speak for itself today.

In Also in
Java Today,

Daniel Steinberg says it's Time for Java developers to put up or shut up: "Off the top of my head I can name dozens of really interesting projects and initiatives in Java right now and many of them are open source in some way or another. We've been looking for people involved in cool Java open source projects to submit session proposals for O'Reilly's Open Source Convention, OSCON, held in Portland, OR July 24-28." If you're involved with one of these projects, act quickly, because the OSCON call for participation closes tonight.

Guy Pardon is ready to throw out the application server for his enterprise applications. In J2EE Without the Application Server, he writes, "this article proposes a further simplification of J2EE, by showing a way to eliminate the overhead of the runtime platform: the application server. In particular, this article shows that many applications no longer need an application server to run." He says the results are apps that are easier to program, install, test, and run. In the article, he shows how to combine the Spring framework with separate JMS and JTA implementations to deliver an enterprise-class application.

In today's Forums,
mpocock has a VM-level suggestion in
Dolphin: play nice with non-java languages:
"One of the major things I'd like to see from Dolphin is the ability to host a much wider range of languages with in the JVM, without effectively needing a VM within a VM. To support ML-style languages efficiently, it would realy help if methods could return tuples. At the moment, methods can have a return type that is void or a java type. This works by leaving any value on the top of an empty stack in the called method, and then popping the stack-frame and setting the top-of-stack index to the return value if there is one. Tuples could be directly supported by just setting the stack-frame to include n values from the invoked method's stack."

In Solving a puzzle using JAI, joshuax112 writes:
"I am starting with JAI and I'd like to develop a program that is able to recognize if 2 outlines (shapings) of the puzzle parts fit together and in which way. The backgroundcolor is white and the part of the puzzle white. How should I start solving this problem? Is Hough-Transformation the right beginning? Is there already some java-code out there in the internet?"

Fernando Lozano wonders What happened to all my Eclipse plug-ins in today's Weblogs:
"I must admit I'm having trouble figuring out the inner workings of the Eclipse ecosystem. Almost all main tool vendors participate in the project and you can find hundreds (if not thousands) open source plug-ins. In spite of that, Eclipse remains a difficult environment to start with, and it's not easy to identify a successful set of 'must-have' open source plug-ins."

Kohsuke Kawaguchi reports that he's been
Neck-deep in JAX-WS:
"For the past few months or so I've been working on rearchitecturing the JAX-WS RI. The goal is to bring the performance to the next level, to make it more pluggable in all respects, and to allow more infrastructure-level specifications to be implemented on top of it."

In the conclusion to his long-running series tracking a user-submitted Mustang fix, John O'Conner finds his fix integrated and released in
Contributing to Mustang: Fixed in Release B70:
"My bug fix actually showed up in build 70 of Mustang. The public test of the Mustang collaboration process is done. My conclusion... the process worked."

In Projects and
Communities,
the Robotics Community home page has announced two robotics-oriented birds-of-a-feather sessions have been accepted for JavaOne 2006: BOF-0503 ("Java Technology in An Intelligent Swarm of Heterogeneous Lego Robots") and BOF-0509 ("Hacking Vex Robotics by Adding a Smart Java Technology Brain"). Both are represented by java.net projects.

Tuning an application server, one that typically has dozens of components and hundreds of parameters, can be a difficult task. In Self Management Framework in GlassFish, Sankara Rao looks at GlassFish's solution to this problem: "GlassFish has a built-in framework to incorporate self management intelligence into the appserver.
