This site is dedicated to Pushlets, an Free and Open Source (LGPL) HTTP-based publish/subscribe framework, now even AJAX enabled. Read this whitepaper to get a first idea of the why, what and how and try out the Pushlet demos. A full DHTML publish/subscribe example is the Chat demo. Additionally, you may want to read my JavaWorld article on Pushlets.
Many other references can be found on the web (e.g. try a search on "pushlets" on Google). In print "Professional JSP" (Wrox Press 1th ed.) devotes text to Pushlets starting on page 610.
More and more Pushlets find their way into applications.
Yes it has been a while ! Mainly some bugfixes and logging (log4j support) enhancements. Download is available from SourceForge See also the release notes.
Various bugfixes and hooks for declarative extensibility. Download is available from SourceForge See also the release notes.
Most important change is the addition of an AJAX JavaScript client. Download is available from SourceForge. See also the release notes.
A first version of a Pushlet AJAX client library is available. Some of the examples like the Chat demo are already using this AJAX client. For several reasons it may be more optimal to use the AJAX library. The AJAX client library is used extensively in my GeoTracing projects for real-time GPS tracking on a Google Map.
You can now download v2.0.0 from SourceForge
The examples on this site now run a preview of v2.0.0. You may want to download preview versions.
As v2.0.0 is under development, following the RoadMap document, I have added a Status document.
Started compiling a list of applications.
Finally it has happened. This site reflects v1.0.0.
The upcoming v1.0.0 supports XML encoded Events.
Working towards version 1.0.0, I completely redid the DHTML implementation. The examples should now work for most browsers (but one never knows!). Also the webpresentation teacher/student example is fixed

During jan-may 2000 this server has welcomed 1000s of unique visitors and about 100s of downloads. I've gotten many positive responses, both from gurus in the DHTML world (Dan Steinman and Danny Goodman) and the servlet world (Jason Hunter). But I am also wondering what your opinion is and if the you are able to get Pushlets working in various servlet engines.
I've set up a Pushlet discussion list at YahooGroups, so that your opinions can be shared. I will forward some of the private email responses I've gotten to that list. Click here to go to the discussion page.
