Overall Architecture

5

JRuby on Rails

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• http://wiki.glassfish.java.net/Wiki.jsp?page=GettingStartedGuide

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/

Groovy on Grails

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• http://wiki.glassfish.java.net/Wiki.jsp?page=GrailsGettingStarted

11

PHP

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> http://wiki.glassfish.java.net/Wiki.jsp?page=GettingStartedWithLiftOnGlassFish
