GlassFish v3 is an application server that supports dynamic languages like JRuby on Rails, Groovy on Grails, PHP, and Scala on Lift. It provides features for deployment, management, and performance of dynamic web applications. JRuby on Rails and Groovy on Grails apps can be deployed as WAR files or using simpler deployment options. PHP applications can use Quercus or the PHP/Java Bridge. Lift apps are also deployed as WAR files.

6. JRuby On Rails
• No packaging, simple deployment
> asadmin deploy depot/
• Deploy as WAR
> warble #creates WAR file
> asadmin deploy depot.war
• Tested JRuby runtime at Updatecenter
> bin/updatetool
> No more config needed
• Commercially supported by Sun

7. JRuby On Rails
• NetBeans support
> Develop, deploy debug

8. GlassFish gem
• Rails developer friendly
• Based on GlassFish v3 nucleus
• Distributed as ruby gem
• Install
> jruby -S gem install glassfish
• Run
> jruby -S glassfish_rails myRailsApp/
• More info
> http://rubyforge.org/projects/glassfishgem/

10. Groovy on Grails
• Development and production on the same server
> Develop using GlassFish v3 embedded server
– grails run-app
> Production deployment
– asadmin deploy grailsApp.war
• Efficient WAR packaging
> grails shared-war
– Creates smaller WARs ~200KB vs 18MB
– asadmin deploy –-libraries $GRAILS_HOME/lib/glassfish-
grails grailsApp.war
• Get Grails IPS package from Updatecenter

12. PHP
• Quercus (Caucho)
> Open Source (GPL) PHP 5 implementation in Java
> WAR packaging
> WordPress, MediaWiki, phpBB, Joomla
• PHP/Java Bridge
> Open Source (LGPL)
> XML based network protocol for native PHP
> Faster, easier than JNI
> Java native threads used for concurrent requests
> PHP and JSP session sharing

13. Scala on Lift

14. Scala on Lift
• Lifts apps packaged as WAR
> asadmin deploy liftApp.war
• For details on developing and deploying Lift
applications see
