The Mustang Regression Contest, and international law
A question that's come up around the Regressions Contest is:- Why are various countries restricted from participating? This has to do with laws and lawyers. No doubt you'll have seen this in other contests, especially if you've read the fine print. The phrase is: "void where prohibited by law" ... In designing this contest we went through an interesting and probably excruciating exercise. We got some lawyers to research for us a set of contest rules that were as compatible with as many countries as possible. That turns out to be very difficult because the law governing contests varies so much from country to country, in incompatible ways. The lawyers did the best they could, but there's only so much one can do to harmonize conflicting laws. Contest home page Official Contest rules  —  David Herron

Grizzly part III: Asynchronous Request Processing (ARP)
The Grizzly HTTP Engine can be extended to support Asynchronous Request Processing(ARP). This time I will describe how to extend Grizzly to support ARP, and will conclude by describing a Google's Gmail Servlet that execute only when new emails are coming. With ARP, Grizzly can now have some sleep, waiting for works.....  —  Jean-Francois Arcand

Accessing Derby from Creator

Yes, I'm a NetBeans guy, but since Creator 2's been released, I can't stop playing with it. Since I've also been playing with Derby a bit lately, and since Derby isn't one of the preconfigured database server types that ships with Creator, I thought a short blog entry might be in order.

Using command-line Ant-based build structure that is Netbeans-friendly
Do you use Netbeans to write your Java EE applications? If so, did you ever want to run the build files through command-line only to discover that they can only be run through Netbeans. In this blog, I will describe a few simple steps that will make your Netbeans generated Java EE projects command-line friendly.  —  Inderjeet Singh

Accessing Google Web Service using JAX-WS
Google has a rpc/enc Web Service for searching and fetching cached pages. There are many ways to access these services(for e.g. Google API). Can it be accessed using JAX-WS? JAX-WS doesn't support rpc/enc Web Services so you don't have nice typed objects to work with. But one can use javax.xml.ws.Dispatch to send and receive SOAP messages.  —  Jitendra Kotamraju

Fast web application redeployment using JMX

Grizzly NIO Architecture: part II
Long time ago I've started discussing the GlassFish new HTTP NIO based engine called Grizzly. After several releases, bugs fixing, fired rills, afraid to write in English and a new member in the family, I'm continuing the exploration of the Grizzly Architecture.  —  Jean-Francois Arcand

Comparing webapp frameworks : Struts
Struts is the grandaddy of Java webapp frameworks so it's fitting that we start our tour here. I think it's probably safe to say that Struts was the first model 2 (web MVC) framework to gain widespread adoption in the Java arena and to this day it's still used by many people.  —  Simon Brown

Java BluePrints AJAX Components in Sun Studio Creator
Java BluePrints AJAX Components are now included in Sun Java Studio Creator release 2. Creator lets you add these AJAX components into your application and easily integrate Google Maps or a progress bar and other cool AJAX features.

Interceptors with EJB 3
I have been having a look at EJB 3.0 interceptors with Glassfish. EJB 3.0 allows you to define interceptor methods that are called around the business methods and lifecycle events on the bean instances. The interceptor methods can either be defined within the bean class or in separate interceptor classes. Interceptor definitions and binding interceptors to bean classes or specific methods within the beans can be done either using annotations or within the deployment descriptors. Here, I will try to provide a simple example of using interceptors on business methods using annotations.  —  Meeraj Kunnumpurath
