82. Endorsements Look like the best deploying option I ever found for Rails, GREAT! the easiest rails stack in the world, jruby 1.2rc, rails 2.3rc, glassfish v3 ... too easy to run jruby/rack/ glassfish behind nginx leading the way to simple, scalable, no-hassle hosting for Ruby web applications. ... it's true one-step deployment . had no reliability and performance issues with Glassfish money is on JRuby (and Glassfish) for the long haul ; if you haven't checked out Glassfish yet, you're doing yourself a disservice! nice way to deploy and manage my app while leaving things open for scaling

83. Who loves Rails on GlassFish ?

87. groovy -e &quot;println 'Hello ' + args[0]&quot; World

89. Templating using GSP (Groovy Server Pages)

90. Tag libraries to create web page components

96. Edit “grails-app/controllers/BookController.groovy”

99. Deploy: “asadmin deploy helloworld-0.1.war”

100. Demo Grails & GlassFish http://blogs.sun.com/arungupta/entry/getting_started_with_grails_on http://blogs.sun.com/arungupta/entry/totd_75_getting_started_with http://blogs.sun.com/arungupta/entry/grails_on_glassfish_v3_embedded http://blogs.sun.com/arungupta/entry/tic_tac_toe_using_rails
