Java Enterprise

On Wednesday I did a presentation on "Scripting and the Java Platform" at the Web 2.0 Expo in San Francisco. Yesterday I put the slides (PDF) online. In my talk, I went over three key components: Phobos (the server-side framework and development environment), jMaki (the client side über-framework) and GlassFish v3 (the server platform). I demoed all three of them, and I'm glad to report that, as...

In the week of April 30-May 4 is another java.sun.com Ask the Experts session, this one on Web Services Interoperability Technology (WSIT) ("a bridge between Java and .NET services") and Project Tango (enablement of "interoperability between the Java platform and Windows Communication Foundation"). You can post questions during that week, to be answered by technical experts Harold Carr, Arun...

Ouf. My trip in Brazil has been extremely cool! Thanks to the peoples here, I was able to give talks on GlassFish, Grizzly and Comet in three different cities (Porto Alegre, Brazilia and Salvador). My last talk yesterday about Web 2.0, Comet and Grizzly was really interesting as the majority of listeners weren’t speaking English. Hence a 'real time' translator was translating my bad English to...

If your application needs a "Hash Table" type of structure you have several options. One is to use the java.util.Hashtable. In a multithreaded environment it would be safe, but not very efficient. If you have a couple of threads that want to read from the hash table, they will have to wait for each other. This wait is not necessary. There is no problem having multiple threads reading a structure...

Após diversas palestras em Brasília, o GlassFish e seu amigo Grizzly estão indo para São Paulo, para o Sun Tech Days. Mas espere! O ágil Grizzly levará também o GlassFish à Salvador para uma palestra no mesmo dia! Isso é o que nós chamamos de escalabilidade :-) . Esta será a sua última aparição antes de voltar para sua fria e nevada casa.... até o JavaOne!

My adventures at FISL 8.0 continue....On Friday, IBM didn't showed up for their Web 2.0 talk and guess who was asked to replace them? With 10 minutes notification, I didn't have a single minute to stress or think. Charlie and I jumped to a crowded room and talked about GlassFish, SWDP and Grizzly Comet. Since Comet is fairly new, we spend a fair amount of time explaning what it is and how to use...

This week is the week! I'm in Brazil for the 8th International Free Software Forum. This conference on open source projects is really interesting and a lot of folks are attempting the conference (~ 5000). My first day was a 'discussions day' and didn't have a single minute to attempt talks! I was around the Sun boot talking about GlassFish, Grizzly and GlassFish's Comet implementation. It is...

In her new article on SDN, Integrating NetBeans IDE Profiler With Sun Java System Web Server 7.0, Sun engineer Yamini Balasubramanyam describes the benefits of performing profiling tasks with the Profiler in the NetBeans IDE and introduces the GUI before explaining the integration procedure with screen shots and example output. What a useful resource! Good job, Yamini.

A new article on Sun Developer Network, An Ajax-Mashup Sample Application on Sun Java System Web Server 7.0, shows you the deployment process on Sun Java System Web Server 7.0, a stable and scalable platform. The sample application that's hosted with the article, accompanied by a screencast demo, is truly nifty, complete with displays of the latest news, weather, stock-quote, traffic, and map...

Yesterday we did a very open review of the Grizzly framework version 1.5. The meeting was open to everybody. We discussed the current framework classes, the migration from 1.0, some performance improvements, etc. A lot of peoples have called, and the interesting part was that the majority of listeners weren't from Sun. To name a few, we got listeners from Amazon, Sun, Noelios, and student from...

At AjaxWorld 2007 last week both Greg and I demonstrated a JMaki demo which is using Grizzly Comet in GlassFish. The code is available under the JMaki workspace but you can also download the war file from here. Just install GlassFish, enable Comet and deploy the application. The application is simple. When you type a word, the word will be displayed using Flickr photos and shared amongs all Comet...

Stacy Thurston, community advocate for Sun Learning Services, has published four postings on reading the Chinese, Japanese, and Thai languages online. I'm amazed at how well he explains the basic concepts.In a separate posting, Stacy describes how to create a simple NetBeans project to make a language choice for your application. Hosted with the posting is a sample project with the related...

Sure there was fluff, fluff is everywhere and TSS Java Symposium was no different. But in the end there were more code examples than SOA hand-waving and even when the so-called SOA gurus went about trying to sell you stuff, they usually backed it up (or at least tried to) with some kind of a demo which would translate through to the lowest common developer. Advertised as the most pragmatic of...

Tim Bray wrote about running servlet-like JRuby scripts inside a web application and I left a comment saying "Phobos can do that". This got me thinking on how to make it easy to get people started in this model. As always, the best way is to use a running application as a starting point. Once the basic application layout and configuration are in place, all you need is a well-defined place for...
