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
