JavaOne 2007 is right around the corner, and I am participating in two sessions there. The first one is based on my work at my previous employer, Sun Microsystems. This session will present tips and tricks on using Java EE 5, and is patterned after the popular Java Puzzler sessions by Josh Bloch. My other session is related to using Google Checkout API in Java applications. In this session, we...

JavaServer Faces 1.2 includes support for Resource Injection and annotations such as @PostConstruct and @PreDestroy. Coming from action frameworks, these 'implicit' hooks make composite presentations a bit easier to pull together, even in the stateless HTTP GET case. JavaServer Faces currently has a couple great frameworks that extend application coordination and ease development. Since not...

This blog is on a personal note. After being at Sun for 10 years, I have now left Sun and joined Google. I am currently working on Google Checkout, Google's solution to make online shopping faster, safer and convenient. If you have ideas on how to achieve these goals better, share them as comments to this blog. When I joined Sun, it was my dream company in regards to the culture and the quality...

The jMaki team has been hard at work re-working jMaki into the .9.x series which now supports all of the intended 1.0 features. At JavaOne we plan to offer a release candidate. If you don't want to wait you can try out the samples from the download page. We only plan on fixing issues so you can use what is there today. JavaOne Sessions and BOFs TS-9516 Using jMaki in a Visual Development...

I don't like being a speaker at JavaOne. Why? Because every year I'm suffering the same problem, which is.....the microphone are locked on the podium. Hence, if you want to move, you can't. You have to stay and speak like a politician for your entire presentation, without moving or even pointing directly the screen, because only the first couple of rows will understand you. To make things worse,...

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...

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.
