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]

There is a jurisdictional issue brewing over the future of internet standards. The dispute is between the WHATWG and the IETF regarding the specification process for the websocket protocol.[Read More]

Jetty-7.0.1 has been extended with a WebSocket server implementation based on the same scalable asynchronous IO infrastructure of Jetty and integrated into the Jetty Servlet container.

The W3C has developed the Websocket API proposal for HTML5, that enables web pages to perform two-way communication with a remote host. There is also a proposed IETF draft websocket protocol to transport the websocket messages.
I believe that there are significant deficiencies in the proposed websocket protocol and this blog looks at how they can be rectified.

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

Bidirectional Web Transfer Protocol - BWTP
I really like the idea behind the HTML5 Websocket API - namely that a datagram model should be used for web application communication rather than a request/response paradigm (this is also the idea behind cometd). But unfortunately, the proposed protocol to carry websocket traffic is neither a good protocol nor is it well specified.[Read More]

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.
