I'm pleased to announce the first release of Grails since the acquisition of G2One by SpringSource. Grails 1.0.4 includes a number of improvements as well as upgrades to key libraries that underpin Grails and can be downloaded from the Grails download page. More specifically Grails 1.0.4 ships with the latest Spring 2.5.6 release that came out a week or so ago.

Beyond the improvements there are a couple of interesting new features in this release. The first is the addition of a feature that better supports mapping of Hibernate user type definitions in GORM. You can now map custom user types…

I am delighted to announce that SpringSource has acquired G2One, the company behind Grails and Groovy.

Why?

I’m excited about this deal for many reasons.

Grails is a great fit with Spring and SpringSource technologies. Grails is built on Spring. It offers another route to adopt Spring, the de facto standard component model for enterprise Java. All the power of Spring (and Java) lies beneath the surface of every Grails based application—a key reason that Grails can scale to enterprise use, as well as a validation of Spring’s power and flexibility.

Like Spring, Grails is a technology that simplifies the lives of developers and makes them more productive. As our new tagline, Weapons for the war on Java complexity, reflects, simplification has always been core to what we’ve done as a company and as technologists…

We are pleased to announce that Spring for .NET 1.2.0 is now available.

Introduction

This will be a series of 3 blogs describing a step-by-step approach to building and deploying GWT applications in the SpringSource dm Server™. The focus of the blogs will be as follows:

1. Building and deploying the GWT StockWatcher sample app as a WAR file in dm Server, using the SpringSource Tool Suite to build it from scratch.
2. Deploying with a "Shared Libraries" approach: How to remove the GWT dependencies from the WAR and deploy them as an OSGi bundle in dm Server.
3. Deploying with a "Shared Services" approach: We convert the single WAR file into OSGi services which can be shared by other applications and hot-swapped out.

It is worth noting that I am not using the Spring Framework anywhere in these first two blogs. Integration between Spring and GWT is a subject in itself and I want to try to keep each blog as focused as possible. In the third blog, I will show how to use Spring to publish and consume OSGi services and how this can be integrated with GWT.

Background

The blog will take a practical step-by-step approach to building the GWT StockWatcher sample described here. The Google tutorial takes you through the steps required to build a GWT sample from scratch using RPC. I will be referring to pages in the tutorial as we go through and discussing the advantages/disadvantages to various approaches.

The blog assumes that you have an install of SpringSource Tool Suite 1.1.1 (I'm using the Eclipse 3.4 version),  dm Server 1.0.0 and GWT 1.5. It also assumes that you have a good understanding of Java programming and a basic understanding of Javascript and Ajax.

For the purposes of the paths used in the demo, I created a new Eclipse workspace at /Users/bcorrie/gwt/workspace. I have included zipped up projects you can download below, which contain a GWT_ROOT_INSTALL variable I have defined. To use my projects, when you import them navigate to "Preferences" -> "Java" -> "Build Path" -> "Classpath Variables" and define your own GWT_ROOT_INSTALL…

No, not the Obama/McCain smackdown on Nov 4. As you may have read in SD Times, SpringSource has been elected to the JCP Executive Committee for Java SE/EE, along with SAP, Ericsson, Nokia, Philips, and IBM. I will be the SpringSource representative.

Not that the JCP matches the scale of the presidential race. But this is an important moment for SpringSource, and one that reflects the years of hard work and leadership the entire team at SpringSource has provided in enterprise Java. More importantly, I believe that our election will help us to make Java stronger.

Last night I presented 'Introduction to SpringSource dm Server' at the Philadelphia Spring User's Group. During this presentation I created a small application called GreenPages, demonstrating all the major aspects of dm Server. I promised the attendees that I would post the application and the slides here.

In the last few weeks since the GA release of dm Server many people have been asking about the best way to get started with dm Server, so I'm using this entry to collect all the relevant information together…
