Swing
The next entry of the Swing in a better world serial
GUI
Information on the new SwingX 1.6.3 release.
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.

Know how persist document in the Cassandra in a way fairly simple
Programming
We coax Rhino (an elusive, misunderstood, and ignored member of the Java ecosystem) into a mind meld, giving it access to the JVM's thoughts, experiences, memories, and knowledge; and take it where no rhino has gone before!
You want JAXB to unmarshal singletons? You already spent lots of time coding rather complex workarounds applying XmlAdapters and afterUnmarshal callbacks? The solution is astonishingly simple!
I mentioned the idea to use Wordle as an execution profiler while presenting the profiling section of my performance tuning course in Paris last December. The idea was seeded by presentation that Neal Ford did a few years ago in which he used Wordle to expose the vocabulary of a Java application. Instead of vocabulary, I wanted to see if Wordle could be used to visualize an applications dominate behavior.
A couple of weeks ago, I sent out a little quiz to my readers of The Java Specialists' Newsletter. No one managed to figure out what the code does without running it. Some managed to explain the result once they had run it. Perfect quiz for weeding out those job applicants you don't like. Especially if you are working in the banking industry. OK, enough hints, let's look at the quiz :-)
Education
This article has the main objective show a little example for persist information in Cassandra using java.
For demonstrated the persistence with Cassandra will used the Easy-Cassandra, a framework open source for use this SGBG in an easy mode.

Many things changed from java 1 in 1995 at java 7 2012. Learn about this reading this article.
A preview of the pure Java version of VisualLangLab is now available. The GUI, and other characteristics, are virtually identical to the previous version, but the JAR file is very much smaller as it does not bundle the Scala API jars.
Tools
I think that Maven is a great tool for development. But it can be used for more. For instance, I've just prepared things so that starting from a clean room you can try out my lightweight CMS, NorthernWind, by just invoking a couple of commands. They will install and run NorthernWind, an embedded server and an example site. More information at the NorthernWind blog.

Old friends may want to gather in Brussels the weekend of February 4-5 for FOSDEM.
Recently there has been a renewed interest into the Actor programming model. The Actor Model actually comes from the '70s, but as far as I'm aware it has been used only in a very limited subset of industrial projects outside the area of telecoms. Erlang (not by chance developed at Ericsson, a telecom industry), which is a language whose concurrency model is actor oriented, is getting some...
Testing
In the previous articles we have concentrated on testing using Glassfish. But can you use the same
recipe to do testing on Weblogic. The answer is YES, but ..... Yea you know there is always a caveat.
First make sure you have Weblogic installed properly. Note I did the testing with the latest 12c version,
so your mileage may vary.
Download the attached zip file again and follow along. In...
Today I decided it was past time to reorganize the slides in the performance testing section of the course. I added a number of new diagrams and charts to help organize the materials and then I went back and started to review some of the definitions that I was using. First up was the question; what is performance testing and how is it related to load testing
J2EE
In the previous article we described how to do testing with multiple containers. But since joining
the Glassfish team I have wondered how can I test applications against different versions of JSF on Glassfish?
As it turns out it is actually quite straightforward. This blog entry shows you how to do it. It will
allow you to test using a 2.1.2 version and up. All by using properties passed in...
In the previous article we have worked out how to run the integration tests against Glassfish,
but what about other versions of Glassfish or even other servers?
Well, the infrastructure groundwork has been laid for that. Before we are going to reap the fruits
we are going to explain the difference between downloading, installing and configuring your server
within Cargo.
The main reason...
In the previous article we added the Glassfish application server into the mix for testing. This looks all nice,but one might wonder how this would work in a parent project (POM) and child projects setup. Well it is fairly easy to accomplish.We will move all the bits first over to the new parent POM we are going to use. See below for what theparent POM will look like.

This page is for introducing Grizzly-Thrift server/client modules and sharing various benchmarking results.
Object serialization/deserialization of Java comes expensive. For improving this lack, we sometimes used to use other frameworks for RPC such as Protobuf and Thrift which support various programming languages, RPC and own data structures.
Especilally, Thrift has already provided various...
