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]

Servlet 3.0 Public Review : Update
I have been working on an implementation of the Servlet-3.0 asynchronous servlets with some the fixes/extensions I suggested in my previous blog and from some continuing discussion within the EG. This implementation demonstrates that significant asynchronous behaviour can be implemented without the complexities of redispatching wrapped requests or the forward(path) methods.[Read More]

Scalable BlazeDS with async Jetty
Valery Silaev has pointed me to an article on flex.sys-con.com that demonstrates how the asynchronous features of Jetty have been used by Farata Systems to achieve some excellent scalability results with BlazeDS.
BlazeDS is an open source server side that provides comet style streaming events to a flex/flash client side (not strictly comet as it is not strictly ajax).

I'm just fresh out of a session at JavaOne where Sun have revealed their road map for the servlet 3.0 specification. My initial reaction is that it contains both some good and bad items as well as quite a few concerns in between. The 10 words or less version is: Annotations, JSF, Ajax, Comet, REST, scripts, security and Misc.[Read More]

Gaming with GWT and Jetty continuations
The Google Widget Toolkit allows Ajax applications to be developed in java code using the traditional UI widget paradigm. The toolkit includes support for RPC, but not for comet style Ajax push. I've been working with Ryan Dewsbury of www.aplayr.com to convert their GWT powered games of risk and pocker to use Jetty continuations. First... play a lot of poker![Read More]
