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.

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...

In today's information technology world, fault tolerance has become an expected system characteristic, as demands on such systems, not only requires the availability of data, but also the efficiency of such systems. By clustering a set of servers, with minimal, or no configuration,  through a dynamic discovery protocol, a compute cluster can be formed to increase compute power, availability...

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. JBoss ESB Config Console Now, you...

Now that jMaki 1.0 is out we have time to look at integration with our JavaScript functionality like the Open Ajax 1.0 Hub. The integration was done using a simple jMaki extension which takes the events from jMaki and republishes them on the hub. jMaki is also capable of registering libraries as they are being loaded. To show the integration we have published a version of the application...

In the spirit of transparency, I'm going to be posting regular updates on the work of the Java EE 6 expert group (JSR-316). For the most part, this is going to be a condensed version of the updates that are sent to registered observers to the expert group. In order to join as an observer, you need to be a JCP member. The instructions to join the observer list are on the JSR-316 community update...

Early in the dot com boom era, a lot of companies implemented the popular portals. Those portals allowed us to "integrate" multiple applications together into a single screen. I write "integrate" between quotes, because there was nothing really integrated, it was just that the set of applications were displayed in the same screen. The reason for the low level of integration was not because of...

Upon installation of the Phobos module, you'll find a newly created phobos directory under the root server directory, containing the Phobos framework, the libraries and some sample applications. Each sample comes with an ant...

In six minutes, you are shown the history and rapid evolution of the publishing world at Sun, from troff to FrameMaker to AdeptEdit to blogs to wikis, thanks to the inventions of GUIs, formatting and structuring tools, and Web-based interfaces. As someone who has used most of those tools over the years...
