Deja 10 ans que je n'avais pas foule le sol Francais:-) This time I was in the middle of Paris to visit two new Grizzly Comet customers....quite interesting to talk in French (and see them smile every word I say!)....I keep repeating myself, but did I say Comet was more and more popular? In only one week I almost talked four times on Comet, and only one time on Grizzly...the Comet revolution has...

After Prague, here comes Stockholm! This time I'm here to work on Sailfin. As I recently blogged on, Sailfin implement the SIP protocol on top of Grizzly 1.Next (1.5/6...and soon 1.7). Having worked with both Comet and SIP, I can clearly see an overlap between the two approaches. I'm not sure how the adoption of the SIP protocol is going on, but one thing I know is Comet is more and more popular...

Check out the transcript on the November 28 live chat on Sun-Microsoft interoperability. During that chat, several technical gurus at Sun answered questions from the participants on the current status of the collaboration between Sun and Microsoft on interoperability—a collaboration that has been going on for three years. Among the topics are desktop virtualization, Project Tango, file...

First, congratulation to the Netbeans team for their new release! One day I'm gonna leave the vim world....And thanks to see so many peoples for the Grizzly Framework talk....and the Comet one! I have to admit, I was happy to see that many peoples listening to an NIO boring talk! Now on Comet, this is great to see that peoples internally @ Sun are starting being interested (always like that......

It is some days that I saw some posts about securing Glassfish in production environment, so I thought I write some of my experience here to let other secure the glassfish easier. There are some basic items that you will need to relay on in order to have a secure Glassfish installation.   secure access to administration console, both web based and CLI. secure all ports and listeners that...

It's great to come back from vacation and find out that open source has worked its magic once again. Landon Fuller's SoyLatte port of JDK 6 and OpenJDK to Mac OS X now runs on Mac OS X Tiger and is sufficiently stable to allow me to run GlassFish v2 on it seemingly without any problems. I tested it with a few Phobos webapps and they ran just fine, as did the admin console. The path to having the...

The Grizzly shows is moving to Europe for the next two weeks starting next Monday. Cities orbited where you may listen to the Grizzly: Prague: Grizzly and Comet Stockholm: Grizzly SIP Paris: Comet and JRuby Antwerp (Javapolis): Grizzly and Comet. If you are a member of a Java Users Group and interested to have a talk on Grizzly and its extensions, feel free to ping me at jeanfrancois dot...

Over the last couple of months, I've learned and worked on the SIP protocol (which share a lot of concepts with Comet). With the help of Ericsson's engineers, we have ported their NIO based SIP implementation to use Grizzly 1.5 and up. The result is quite amazing. With only two classes, Grizzly can now support the SIP protocol over TCP, UDP and TLS! TLS wasn't supported at all before the use of...

New on Sun Developer Network is an article, Deploying PHP From Cool Stack in Sun Java System Web Server. The title speaks for itself: The article shows you how to do the deployment on the Solaris Operating System, known for its performance, stability, and security. Only a few short steps are involved.If you're new to open-source Cool Stack, do check it out. It's a group of common applications...

A two-week vacation exacts a high price in catching up. But I had a fabulous time in Hong Kong and Xian early in the month so no gripes whatsoever. Speaking of catching up, I just caught up on a podcast that I'd meant to listen to for a while: Innovating in a Commodity Market, an interview by Sun VP of global systems engineering Hal Stern with Sun cofounder and Systems Group chief architect Andy...

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 that Virgin Megastore is a JSF User. Within Sun, we have an elevator pitch-like slide deck about JSF, and the most important slide therein is at the left. If you want more details about the sites pictured, or you...

Take a look at a recently published IDC paper (in PDF), Sun Developer Services Portfolio: The Whole Story, which describes the Sun Developer Network (SDN) offerings for individual developers and engineering teams. 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...

Finally the slides from the Zilonis Rules Engine JavaOne presentation are available. In the slides I presented the internals of how Zilonis uses the Java Concurrency API's to manage concurrent access to the Working Memory.
