The websocket protocol has been touted as a great leap forward for bidirectional web applications like chat, promising a new era of simple comet applications. Unfortunately there is no such thing as a silver bullet and this blog will walk through a simple chat room to see where websocket does and does not help with comet applications. In a websocket world, there is even more need for frameworks like cometd.[Read More]

Cometd Features and Extensions
The cometd project is nearing a 1.0 release and thus we are make a bit of a push to improve the project documentation. As part of this effort, we have realized that there are many cool features and extensions to cometd that have been under-publicized. So this blog is an attempt to give a whirlwind tour of cometd features and extensions.[Read More]

Jetty-6 Continuations introduced the concept of asynchronous servlets to provide scalability
and quality of service to web 2.0 applications such as chat,
collaborative editing, price publishing, as well as powering HTTP based
frameworks like cometd, apache camel, openfire XMPP and flex BlazeDS.
With the introduction of similar asynchronous features in Servlet-3.0, some
have suggested that the Continuation API would be deprecated. Instead,
the Continuation API has been updated to provide a simplified portability run asynchronously
on any servlet 3.0 container as well as on Jetty (6,7 & 8).
Continuations will work synchronously (blocking) on any 2.5 servlet
container. Thus programming to the Continuations API allows your
application to achieve asynchronicity today without waiting for the
release of stable 3.0 containers (and needing to upgrade all your
associated infrastructure). wt58jhp2an

The announcement of Google Wave is a bold declaration of where google sees the future of the web. Google, unsurprisingly enough, sees the future of the web as a server side paradigm, with dynamic updates being used to drive the thin client model to capture even more of tasks that where once done client side. Google are extending the server side model of webmail to apply to applications that have been fundamentally client side, such as document authoring, IM and chat.[Read More]

Servlet 3.0 Proposed "Final" Draft
I previously strongly criticised the Servlet 3.0 JSR-315 process and the resulting Public Review Draft, describing it as a: "poor document and the product of a discordant expert group (EG) working within a flawed process" and of producing a "Frankenstein monster, cobbled together from eviscerated good ideas and misguided best intentions".
... I'd like to focus on the improved spirit of the group and highlight some of the technical achievements that have resulted.

Maven, m2e and the Nexus Repository manager
Jetty-7 is moving to eclipse, cometd-java is moving from jetty to cometd.org and the maven build system for dojo has been moved out of the main dojo tree. So I'm involved in some major refactoring of three interdependent projects at the same time. This refactoring would be impossible to contemplate without the tools support for these projects. Maven, m2e and nexus are making my life a lot easier![Read More]
