One of the nicest things about working on an open source project is the atmosphere of community collaboration and brainstorming that it fosters. The GWT engineering team has been listening hard to the community about how GWT can be improved, and we’re excited to take you on a tour of the powerful new features that have resulted. GWT 2.0 contains huge improvements

Terracotta continues its open source project acquisition tear today, bringing the the Quartz Scheduler project into it's fold. This latest move follows the acquisition of the EhCache project back in August.

I've been working on getting a REST + Hibernate application using the goodies found in Spring 3.0 for my upcoming book - Spring Persistence with Hibernate. I'm unfortunately slightly disappointed at the current state of affairs (sorry Arjen and Chris). Spring 3.0 is in RC2, meaning it's had 2 Release Candidates, but the REST stuff is still not 100% right.

DZone recently caught up with Willie Wheeler, author of Spring in Practice (Manning) and long time Java consultant. In this interview, Willie provides an overview of the Spring portfolio of projects, including the Spring Framework and provides some guidance on when Spring is a good choice – and when it is not. While Spring has provided tremendous productivity gains for enterprise development, “there are certain incongruities between the Spring of yesterday and Spring today,” according to Wheeler.

In this article, Keith will take you through some of Spring 3's type conversion and validation enhancements. Whether you are developing a traditional web application, a desktop application, or a "next-generation" RIA, data binding, type conversion, and validation are important areas. As you'll see, Spring 3 gives you a significant upgrade in each of these areas while preserving backwards compatibility with previous releases.

I have always wanted to have generator in Java. After all, Python have this feature, Ruby and C#(*) too. A generator is a way to define an iterator but instead of implementing hasNext()/next(), you just implement a method (here generate) and use the keyword yield (or here a method yield) to send value that will be returned by next().

Today, a tantalizing announcement by Mark Reinhold about closures in Java 7 has made its way through the twittersphere. On the same day, Neal Gafter updated his closures proposal. Here are some use cases...

In the first 2 parts of this series on Gradle, we have migrated a simple project from Maven to Gradle, and written a custom task and plugin for use in our future builds. Today, we are going to deploy the plugin to a repository, and then add the other parts of the MoneyPile project to a multimodule build.

After not finding the full set of silent install options by searching, I decided to hunt them down myself and posted a write-up on silently deploying JDK 6.

Those of you who've seen me speak on Java 7 at various conferences have heard me lament (in a small way) the fact that Sun decided last year (Dec 2008) to forgo the idea of including closures in the Java language. Imagine my surprise, then, to check my Twitter feed and discover that, to everyone's surprise, closures are back in as a consideration for the Java7 release.

Creating services is quite an abstract subject, everyone has his own ideas and preconceptions, so is worth clarifying what I mean by services in this article. A service is a component that holds some business logic which can be easily reused anywhere else in the application no matter where the service is located, or what the communication mechanism is used between the client and the service. The following code samples detail my own personal approach on how to implement services in Java.

Jack Cough on Software: Scala over Ruby - My Debate Ends: This article struck a chord with me today. I spent most of today flipping back and forward between Ruby and Scala. I’m working on a project where I’m writing some Ruby talking over sockets and streams and files and I needed something JVM flavoured on the other end.

More updates today on the closures announcement for JDK 7. Google announced the release of its source code for Chrome OS and the NSA announced that it helped beef up security in Windows 7.

In the previous post to this blog, we looked at orchestrating JBossESB services from a RiftSaw BPEL process. In this post, we'll look at the other side of the RiftSaw-JBossESB integration; invoking a RiftSaw BPEL process from an ESB service.

est-Driven Development, or TDD, is often quoted as an essential Agile best practice, and so it is. It works wonders on green-fields projects and new code bases where you can start afresh and ensure that all your code is both easily testable and well tested. But what about legacy code?

When developing a piece of software that has a lifecycle that spans over several years and periodically is released you have to do regression testing, i.e. making sure that previous features doesn't break because of new stuff. Amongst other, we use Selenium and Hudson to do automated regression testing, here are some words about what we do...

Here we are looking into a nice plugin for the Eclipse IDE for analyzing the dumps. Compared to the basic tools described in the previous article Memory Analyzer Tool (MAT) offers better usability, performance and some high level analysis and report tools.

In this post, I will touch on the steps I took to migrate the nofluffjuststuff.com code base to Groovy. Next to quitting a job that sucks, migrating to Test Driven Development & Groovy is just about the best thing a Java developer can do to improve life on the job. I won't go into the technical details. I simply want to join the chorus of those highlighting the benefits of Groovy & TDD and show some results.
