Case Study: GWT & Comet Integration with the Spring Framework at NYSE Euronext ATS
This presentation will cover basic GWT (Google Web Toolkit) and Spring integration as well as more advanced integration using Comet for server side push. The advanced example will use Dojo's Comet Library with the Bayeux Protocol. GWT & Comet were investigated and chosen based on requirements to develop a new web based application to monitor trades that is as responsive as possible and can run in most browers without any plugins. GWT and Comet help address both of these requirements."

I'm presenting this year at SpringOne Americas 2008. I'm really looking forward to it and have been working on examples and the slides for the conference. That's why I haven't posted much lately. I'll be presenting a Case Study of my investigation of GWT, Comet, and Bayeux integration with Spring for developing a trade monitor. I'll be posting the examples soon and will also write about them, but the slides will just be for those that the attend the conference. It should be a very good conference. I really enjoyed it last year. It's one of the more technical conferences I've been to.

I'm making good progress integrating GWT & Comet with Spring. I just posted an update to the Spring by Example Web Module for a basic Spring GWT Controller and Spring Bayeux configuration for Comet on Jetty. Basically there is a Spring version of the Bayeux implementation and can configure it completely in Spring. Then it can be injected into BayeuxService implementations and there is a servlet that gets Bayeux from Spring instead of creating it. I think I'll possibly have a GWT version of the Dojo Comet Chat example soon.

The Spring by Example main RSS feed has been updated to a new url, which is http://www.springbyexample.org/feed/. Before the feed was generated by the TWiki so it wasn't also including the static examples. Also, sometimes something on the TWiki was accidentally posted before it was ready and then stayed in a bad state on sites like Google Reader. The TWiki RSS feed is still active.
