In this two part article, I will explain how to configure a web application built with Maven to support "branding", or skinning. That is, support different distribution skinned with particular images, logo, background, text.

Awhile ago, the java.net Program Manager approached me about blogging about some of the day-to-day interactions I've had with the Java community over the years, primarily the
One the comment I'm getting about Atmosphere is why should I use the framework instead of waiting for Servlet 3.0 Async API. Well, it simple: much simpler, works with any existing Java WebServer (including Google App Engine!), and will auto-detect the Servlet 3.0 Async API if you deploy your application on a WebServer that support it.
To make a fair comparison, let's write the hello world of...
The past week's poll results indicate that, in general, Java developers are of the opinion that the JCP performs a necessary but difficult task. The poll drew a relatively small number of votes: 171. The exact question and results were:
What's your view of the JCP's role in guiding Java's future?
40% (68 votes) - It does a good job of ensuring Java's stability
20% (34 votes) - I often...

So far I have described how create server applications that handle call, conference and IM using SailFin CAFE. In this edition lets take a look at how to add communication capabilities to web applications in a (very) simple way.
I like to start with the code. So, here is some code that implements making a phone call between two parties from the web application.
package my.test;

I'm will be leaving Québec next week for talks at JFall, Paris JUG, Prague JUG and Devoxx. The talks will focus on Atmosphere and it's spin off (Grail Plug In, Akka, PrimesFaces) and a little bit of Grizzly's work-in-progress Servlet Container.
First, I will stop by Amsterdam November 11 and talk about Atmosphere at JFall 2009. Next I will stop by Paris JUG November 12 for an al-in-French talk...

Writing a publisher/subscriber (PubSub) is quite simple with Atmosphere using the atmosphere-jersey module. The main idea here is to use Comet for suspending the response when a client subscribe to a topic, and use REST for publishing messages to the those suspended responses. First, let’s bind our application to the root uri using the @path annotation
package org.atmosphere.samples.pubsub;...
Java.net has a long-standing tradition of publishing high-quality full-length Java technology articles. We also have a vibrant blogging community, and active forums. While these types of content can cover pretty much any problem that Java developers would find themselves facing, it seems like there's room for at least one more new type of content. For this reason, today we're re-introducing the...

This week we're spotlighting the java.net KS-2009 project, which is developing software to solve two-, three-, and four-variable Karnaugh maps (k-maps) on the J2ME platform. Karnaugh maps were invented in 1952 by mathematician Edward W. Veitch, and further developed in 1953 by physicist Marice Karnaugh, both of whom worked for Bell Labs. K-maps are usefule for solving Boolean algebra functions...

Last time, I introduced some of the new Groovy support available in Maven 3, and looked at how you will be able to write your pom files in Groovy, or in other non-XML notations. In this article, we'll take a further look at what you can do with a Maven pom file written in Groovy.
Jason Dillon, the guy who brought us GMaven, has been working hard on extending the Groovy pom scripting features...
