Grails, Java(JSF/JPA), ROR comparison from Java One

I came across a very interesting web framework comparison between Grails, Java(JSF/JPA), Ruby on Rails from Java One. At the end of the day, the framework of choice still depend on the needs of your projects and available resources. Here are the links:

Things could get more interesting when we could see ROR with JRuby and Grails version 1 to be release hopefully on October.
