Subject: Pushlets
Hi,
I am experimenting with a technique I call "Pushlets". These allow a
direct notification of DHTML clients from within a Java servlet (or
other) server. I have gotten room on a site on
http://www.fluidiom.com:8080 where there
is a whitepaper, examples, open source etc.
The technique itself is utterly simple: in a hidden HTML FRAME a HTTP
connection is kept open through which lines of JavaScript are pushed
and interpreted by the browser. A small publish/subscribe framework on
the server takes care of wait()/notify()-based event handling and other
things like queueing. Within the server the framework could be connected
to "real" messaging products or Jini events. There are also adapters for
Java clients (who can receive events as XML or serialized objects).
Through a "Postlet" clients can also publish events. I see Pushlets
basically as a web-frontend adaptor for events, just like JSPs/servlets
are for EJBs.
I would like to discuss this technique in a W3C forum since it relies on
HTTP streaming
somewhere I tried WCA but couldn't add myself (server
did not respond) as contact. Could you point me to possible W3C
list/forums or similar work done ?
thanks,
