Introduction

This is the final blog in a series of three describing a step-by-step approach to building and deploying GWT applications in the SpringSource dm Server™. The first blog looked at the process of creating a simple WAR file from a sample GWT application and the second blog turned the GWT dependencies into an OSGi bundle which can be shared across multiple applications. This final blog will further modularize our GWT sample into OSGi services using Spring Dynamic Modules. This should clearly demonstrate the benefits of OSGi modularity: The ability to remove and replace services at runtime, seamlessly managing multiple versions of bundles and how straightforward it is to deploy and manage using dm Server.

This is the only blog in the series to actually use the Spring Framework. Spring is used to configure the Spring Dynamic Modules and publish and consume the OSGi services. It also demonstrates one mechanism of bridging the world of Spring-managed beans with GWT remoting. However, I'm well aware that Spring/GWT integration is a significant topic in itself, so I'm purposefully keeping to the one simple solution here.

Please see Part 1 for the background to the GWT StockWatcher sample and the software I'm using.

Update: Most of the code examples shown below are out-of-date and superseded by those shown in the more current "Using Spring BlazeDS Integration 1.0" post.

Today we announced the public availability of the first milestone release of the newest member of the open source Spring project portfolio, Spring BlazeDS Integration. This project's purpose is to make it easier to build Spring-powered Rich Internet Applications using Adobe Flex as the front-end client. It aims to achieve this purpose by providing first-class support for using the open source Adobe BlazeDS project and its powerful…

Dear Spring Community,

I'm pleased to announce that the first public development milestone of Spring BlazeDS Integration, the newest member of the open source Spring portfolio, is now available.
Download | Reference Documentation | JavaDocs | Changelog

This is a foundational release that sets the stage for using Adobe Flex and BlazeDS in conjunction with the Spring programming model to build Rich Internet Applications.  We have a number of further integration ideas in mind already for the next milestone, and I would like to invite the community to get involved by trying out this early preview and giving us feedback in the community forum and Jira as we progress towards a full-fledged 1.0.  Check out Using Spring BlazeDS Integration 1.0.0.M1 to get started.

Spring BlazeDS Integration Lead      

Spring Integration last week went 1.0 GA and so, inspired by Adrian's keynote (no, not the Monty Python sketch, just the Grails live-coding example) from SpringONE Americas, I thought it would be fun to show how to take advantage of Spring Integration in the slightly different setting of a Grails application.

Please note: This is a cross post from my own blog @ www.russmiles.com

This series of articles will look at how to add Spring Integration to Grails in a number of configurations that will eventually lead to a full Grails plugin for Spring Integration. More like an online diary, you'll get the chance to see how we take our first steps by bootstrapping Spring…

As promised to the attendees of my sessions, here is the content for my dm Server and concurrency sessions.

Introduction to dm Server

The slides and demo code for this presentation were attached to my previous entry: Getting Started with SpringSource dm Server.

While I was at the conference I met with David Winterfeldt from Spring by Example who pointed me at his great dm Server tutorial.

Advanced Concurrency

The slides for the Advanced Concurrency presentation can be found here and the demo code is here. Slides from last year's concurrency presentation can be found here.

Juergen Hoeller's latest blog announces the release of the first milestone for Spring 3.0. The main highlights are the addition of REST support, the Spring Expression Language (EL) and the move to Java 5 and above. The blog post contains the details.

I'm pleased to announce that Spring Framework 3.0 M1 is finally available for download!

This release features several major changes, including a start of the major 3.0 themes such as EL and REST support:

• revised project layout and build system with module-based sources
• updated entire codebase for Java 5 code style (generics, varargs)
• updated to JUnit 4.5 and JRuby 1.1
• introduced Spring EL parser (org.springframework.expression package)
• introduced support for #{...} expressions in bean definitions
• introduced expression-enabled @Value annotation for embedded expressions
• introduced @PathVariable annotation for URI template handling in MVC handlers
• introduced default value support for @RequestParam in MVC handlers
• introduced @RequestHeader annotation for HTTP header access in MVC handlers
• introduced AbstractAtomFeedView and AbstractRssFeedView base classes
• introduced <spring:url> and <spring:param> JSP tags

as well as various minor enhancements.

Note that Spring Framework 3.0 requires Java 5 or above and J2EE 1.4 or above. We are building on Java 6 and Java EE 5 as the primary platform levels - but rest assured, we will retain compatibility with Java 5 enabled J2EE 1.4 servers such as WebLogic 9 and WebSphere 6.1.

We also removed/deprecated several classes that became outdated. More information…

We just announced a new product called the SpringSource tc Server this week at the SpringOne Americas conference. Springsource tc Server is an enterprise-class web application server based on Apache Tomcat.

Although SpringSource is not the first company to build a product around Apache Tomcat (WebSphere Community Edition and JBoss both embed versions of Tomcat in their J2EE application servers and the developer release of JBoss Web 2.1.1 also embeds Tomcat), tc Server is unique in that it preserves the Tomcat servlet/JSP programming model. Applications written to Tomcat are 100% portable to…

Dear Spring Community,

I'm pleased to announce that we have released Spring IDE 2.2.1. This version is mainly a bugfix and maintenance release but has some significant user level changes as well.

Get more information at the Spring IDE blog

Watch out for more tooling related announcements from SpringOne during the upcoming week.
