Grails has a new release so I spent a little time with it last night and during lunch break today. The new release looks much improved over what I looked at last year, but really, Groovy is not as flexible as Ruby, and Grails lacks the quality of Rails at this point. That said, Grails is a technology that I am hopeful for, much like I hope that JRuby gets fast and well supported as a platform for running Ruby code on. When I write JSP+POJO+Hibernate web apps (my preferred light weight Java stack), I like to use custom tag libraries and Grails’ nifty way of writing tag libraries looks very cool indeed.
