My Comet related blogs recently passed more that 55000 hits. It's probably low for a lot of blogger, but since Comet is fairly new, I consider this as a good sign of the growing importance of Comet. And the count is still growing fast....The first one of the series (aka The Grizzly Comet or why space shuttle Discovery launch was delayed) is by far my biggest read blog (much more than the one...

Since day one of Grizzly Comet, I'm getting requests on how to use DWR's Reverse Ajax with the monster. Well, I did my lesson and looked at the DWR's code (quite good) and submitted a patch. Most probably the next official release will contains Grizzly Comet support (Read below to download a preview)! The result is quite impressive!
Since DWR already supports Jetty Continuation, it wasn't that...

Jetty 6.1.6 has been released, and that release can now run using Grizzly 1.6.1. 6.1.6 - 1.6.1...7.7.7...a new monster is born!
Greg recently announced the availability of Jetty 6.1.6. As usual, the Jetty community is doing great job of delivering a very nice product. Among the new features, I've recently ported Grizzly support in Jetty, removing the dependencies of Grizzly 1.0.x and instead...

After 3 years, I'm really happy to be back as a speaker at the annual ApacheCon conference! Today I've presented the Grizzly Comet (using Grizzlet) in front of a crowded room and guess what, event the iPhone demo running Grizzly Comet worked well! Curious to see what we have presented? I've uploaded the slides here. Unfortunately (for now .. the framework code will soon be available here :-)),...

After months of inactivities, I've updated the Grizzly's Bayeux implementation (previously called gCometd) to reflect the current 1.0 specification. I'm no longer using the gCometd name based on a note I've read from the cometd-dev team, who recommended to not use their name. But first, thanks to the community for the great feedback I got from the initial Bayeux implementation in Grizzly. Wow the...

Graphical Indicators of JSF Usage
From time to time, the JSF team at Sun surfs around a bit looking for
new Internet sites using JSF. This time, my colleague Roger Kitain discovered

pitch-like slide deck about JSF, and the most important slide

The offerings include technical resources (articles, tips, community blogs), forums, technical conferences (JavaOne, Tech Days), training and certification, services, and others. On...

We run a lot of tests of Metro on Hudson with GlassFish, but there's one common problem we had.
Namely, often test jobs abort in the middle, leaving an application server running behind. This not only wastes memory, but it also wrecks havoc to successive builds that attempt to start the server on the same port.
Obviously you can shut down a server if you have access to asadmin script, but for...

At least something good happened during the last AjaxWorld (which seemed to be quite low on peoples): I've meet Ted from ICESoft and we decided to explore how we can implement support for Grizzly Comet in ICEfaces.
Ted has all the technical details about how to enable it here. In the process of making Grizzly Comet working with ICEfaces (useful use case learned by Papa Grizzly :-)), we have...

Sun engineer Sriram Natarajan and I just coauthored an article on SDN, Running PHP With Quercus in Sun Java System Web Server, which describes how to configure Quercus, an open-source, Java implementation of PHP 5, as a Web application within the Web container. You can then seamlessly run PHP-based applications, for example, Drupal and MediaWiki, within Sun Java System Web Server.
The steps are...

I am very happy with new features inside JBoss ESB 4.2, mainly about Consoles and Editors! Yep, JBoss is well knowed by their black console screens logging everything you want into console/cms window. However, in the SOA World, some visual effort is required to be considered "An Enterprise Player", so far, some of this requirements are present in JBoss ESB 4.2.
