Recently I had the privilege of writing an article for Java Tech Journal about using HTML5 Server Sent Events in a JSF 2 User Interface.

"The multicore challenge" is the challenge to developers of software products to write code that effectively utilizes modern multi-core / multi-processor computers. Two years ago, I wondered if the multicore challenge was still relevant. In part, I was thinking about how applications were moving from the desktop into the cloud. So, if the apps people are running are running in a browser, does it matter if their desktop system (or pad or phone) is multicore?...

When I first heard that Oracle planned to start having JavaOnes on continents other than North America, I thought that was an excellent idea. This coming Tuesday through Thursday, the second JavaOne Latin America will take place in São Paulo, Brazil...

I was fortunate to be able to attend JavaOne this year. There I perceived a new energy, focus, and momentum within the Java community that hasn't been evident in many years. So, at JavaOne, I decided to write a series of blog posts describing what I was seeing. There's a lot to write about...

My previous post ("Is Java Really Losing Popularity Among Developers?") elicited a voluminous and varied response, particularly on reddit (489 comments as I write this), and also in the comments posted on the blog itself. In this post I'll touch on a few of the comments, talk a bit more about what TIOBE plots might actually mean, and return to JavaOne 2011...

The results of our recent poll that overlapped JavaOne 2011 indicate that news from JavaOne 2011 related to Java 8, JavaFX, and Java EE was considered most significant by the developers who chose to vote in the poll. A total of...

It's clear that I'm not the only one who considers JavaOne 2011 to have been momentous in many ways. If you weren't there (and, of course, that means more than 99.9% of Java developers), or if you were there and missed more than you saw (was anything else possible?), you can (re-)experience some of the key technical sessions by visiting the JavaOne 2011 section on Parleys.com...

Another JavaOne has finished. Here are my impressions of the final day, touching on community, impatience, coffee makers, and German rhinos), as well as my thoughts about the conference as a whole.

My JavaOne talk about Apache Wicket went really well: the room was almost full, lots of interesting questions and I met a lot of nice people. Thanks to all atendees!

The very last thing JUG-AFRICA founder Max Bonbhel did at JavaOne 2011 was to spend a few moments with me chatting about Java User Groups in Africa and the unique problems they, and African developers in general, face. Despite the obstacles, growth of the Java community in Africa is surging...

Some Wicket goodies for my JavaOne talk.
If you go to my JavaOne 2011 talk "Productively Fun Web Development with Apache Wicket and Java EE 6" you will see a demo where Bean Validation is used in conjunction with Apache Wicket.
In order to accomplish that, all that you need is a single Java class that bridges the Wicket validation framework and the JSR 303 validation engine.
I am...

It's the third day of Java One. No keynote today, but I write about the thrills of the Script Bowl, alternative languages for Java EE, OpenEJB, and the GreenFoot and BlueJ projects for computer science education which I hope Oracle will continue to fund.

The end of JavaOne 2011 is approaching. Yes, officially only 2 days of a 4 day conference have been completed -- but it feels like most of the headline news has already broken. Then also, some of us have been here since late last week (the java.net Community Leads meeting was on Saturday, Oracle ACEs had events before that, etc.). Today is my last full day at JavaOne...

Today I report on another keynote, plans for JDK 8, my thoughts on Java FX and why it's important and why a JSR should start now and not in a year or two, and about kittens.

Tuesday morning at JavaOne, I spoke with London Java Community leader Martijn Verburg about the LJC's decision to seek a position on the JCP's Executive Committee, the JCP.next (JSR 348) effort, the outlook for JUGs and the JCP, JavaOne, Java...

If you regularly visit java.net's "Java news" tab, you'll be accustomed to seeing blog posts by Dustin Marx featured there. Dustin is here at JavaOne 2011, and he's putting together an excellent collection of what this year's JavaOne is all about...

There is one talk I would like to comment on today: "Don't Be Pwned: A Very Short Course on Secure Programming in Java".
This talk, presented by Robert Seacord and Dean Sutherland from SEI/CERT, was the scariest Java talk I have ever been to.
Do you believe the software you write is secure enough? Believing it or not, I suggest you take some time...

Day 1 brings a painful/exciting keynote, an awesome performance by Scala God Paul Phillips, news about Lambda and Jigsaw, and the Tragedy of the Commons.

The blur phase of JavaOne 2011 has started for me. I quickly realized this morning how brief 30 minutes between sessions is, when during that time I want to check out the best JavaOne related blog posts on java.net and elsewhere, update the java.net site, and post some blogs of my own. It's simply not possible...
An experience is relevant only if it can prevent you to repeat the same mistake.

Introduction
Make it compliant! Yes, Ladies and Gentlemen, Make it compliant! That is my tip of the day and the statement I woke up with today. Like many of you, I have read the Jsf-spec pdf file and as you may know, JSF 2.2 is coming with two major features : Faces Flows and Multi-templating. Did...
