I'm glad to announced that yesterday afternoon there was a new addition to our family.

Mihir Gupta, our 2nd son, was born.

Big brother is "extremely happy" and waiting for young one to come home. And mom and dad are revising their skills :)

Date	Jun 1, 2008
Weight	7 lb 3 oz
Length	20.5 inches

"Mihir" means Sun and he is glowing our lives for the past few hours now.

The whole family is excited for the new one's arrival. This blog will take a short vacation to take care of the new born.

Tic Tac Toe using Rails and Grails on GlassFish v3

GlassFish v3 is a modular (OSGi compliant), embeddable (runs in-VM) and extensible (hosts non-Java applications) Application Server. The "extensible" part was demonstrated during JavaOne 2008 by deploying Rails, Grails and Django sample application on GlassFish v3 Technology Preview 2. This blog announces the availability of Rails, Grails and (of course!) Java EE version of the demo code.

The sample application is a simple multi-player game that can be played on Internet and deployed on GlassFish. One of the simplest multi-player game is Tic-Tac-Toe. The complete instructions to checkout, build, deploy and run the sample are available here. The demo can certainly be improved by using the best practices from Rails and Grails and I'll work on them in next few days.

The demo is played in 2 different browser windows (tested on Firefox, Safari & IE). The clicks in the grid on one browser are displayed on the other browser (propagated using GlassFish Comet) and row and column winners are shown.

Some points highlighted by the demo are:

GlassFish v3 supports deployment of Rails and Grails applications, in addition to traditional Java EE apps.
GlassFish v3 has a completely modular architecture as evident by the pluggability of JRuby/Rails.
Features of the underlying GlassFish runtime can be accessed.

Any click in the grid is pushed to the endpoint and then propagated to all the clients using GlassFish Comet. So effectively, now you can build Comet-enabled applications using Rails and Grails.
Rails application is deployed as a composite application where Serlvet is bundled with the application and accessed from the View.
