Jan Bartel and I will be presenting a "Guide to Jetty" Webinar on Thu, Apr 8, 2010 8:00 AM – 9:00 AM PDT. We’ll present an overview of Jetty and then show some hands on examples of running Jetty, deploying webapps, coding against the embedded API, plus a cometd Read more…
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 Read more…
Jan Bartel (Intalio) and Daan Van Santeen (Progress FUSE) will be giving a series of live webinars on how Jetty, Cometd and ActiveMQ can be used to provide a reliable messaging platform to the browser. What Jetty is and how its CometD Bayeux implementation implements messaging to the browser What Read more…
There is a jurisdictional issue brewing over the future of internet standards – I know because I’m stirring the pot. The dispute is between the WHATWG and the IETF regarding the specification process for the websocket protocol (which I have some concerns about, but none the less is supported by 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. WebSocket came out of work on HTML5 by the What Working Group to specify a mechanism to allow two way communications to a browsers. Read more…
Background The W3C has developed the Websocket API proposal for HTML5, that enables web pages to perform two-way communication with a remote host.

In his Homesteading in the Noosphere essay, Eric S. Raymond likened the creation of open source projects to homesteading on a frontier, via a process of “mixing one’s labor with the unowned land, fencing it, and defending one’s title”, in contrast to the lawful transfer of title that occurs in Read more…
Jetty now has available an asynchronous implementation for BlazeDS which uses Jetty 7 portable continuations. BlazeDS is an open source serverside web messaging technology. It provides real-time data push to flex/flash clients using techniques, such as polling and streaming, to provide a richer and more responsive experience. The asynchronous implementation Read more…
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 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. wt58jhp2an With the introduction of similar asynchronous features Read more…
