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]

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]

Clustering cometd with Terracotta.
I recently attended a Torino JUG meeting and saw Jonas Bonér speak about transparent clustering with Terracotta. It was an interesting talk and went a long way to alleviating the concerns I have with the star architecture of terracotta. Thus I wanted to try out a terracotta cluster, but I thought that simply clustering HTTP session in jetty was a bit obvious, easy and above all boring. So instead I used terracotta to cluster the jetty implementation of cometd.[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]

XmlHttpRequest BAD - Messaging GOOD
XmlHTTPRequest is the wrong API on which to base Ajax communications. A messaging paradigm is needed within our Ajax libraries and support is needed in the browser.[Read More]

I have reconsidered the API for asynchronous servlets that I proposed in my recent blog - it is not good!. It makes some of the same mistakes as weblogic and tomcat have made with their asynchronous extensions. So let's have a brief review of all the available and proposed solutions...
