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]

JSR-315 has produced a Public Review (PR) of the servlet 3.0 specification, which unfortunately is a poor document and the product of a discordant expert group (EG) working within a flawed process.[...] Significant effort has been put into the PR proposal [...] but unfortunately it has become a Frankenstein monster, cobbled together from eviscerated good ideas and misguided best intentions. The 8 methods of the ED proposal that were rejected as being too complex and confusing have been replaced by 20 methods and 3 new interfaces! [...] The EG is desperately in need of community feedback and probably another round of Public Review after a beta RI is made available.

Asynchronous Restful Webapplication
This blog annotates the Jetty 7 example web application that uses Jetty asynchronous HTTP client and the proposed suspendable servlets 3.0 API, to call an eBay restful web service. The technique combines the Jetty asynchronous HTTP client with the Jetty servers ability to suspend servlet processing, so that threads are not held while waiting for rest responses. Thus threads can handle many more requests and web applications using this technique should obtain at least ten fold increases in performance.[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]

The Jetty 6.1.0 release is now available via http://jetty.mortbay.org. It represents both a stabilization of the features already released in 6.0.x, plus a raft of new features. For a full description of Jetty 6.1, see http://docs.codehaus.org/display/JETTY/.[Read More]
