Sorry, I sincerely don't want to start a flame war here.<p>I've been looking for a web framework that runs on top of JVM. At the first glance, I like what Grails is doing. So I did a quick Amazon search for books about Grails, and it seems that the most recent book is of June, 2009. Is this a bad sign for a web framework?<p>Also, it would be interesting to hear your opinion of Grails.<p>Thanks!
On the contrary, it's thriving. Grails 2.0 just released last month and it will take some time for new publication to pick up the new stuff.<p>Read the only ref doc.
I don't think Grails was much alive (in terms of adoption) at any point in time.<p>It is as it ever was, there is even a new version out.<p>You'd be mostly on your own + SpringSource, though, don't expect a Rails/Django sized community, or even a Sinatra or CakePHP sized one...<p>Groovy itself, the component language, has also lost a lot of core developers and momentum, especially the project lead at most of the language's development:<p>"In July 2009, Strachan wrote on his blog that "I can honestly say if someone had shown me the Programming in Scala book by Martin Odersky, Lex Spoon & Bill Venners back in 2003 I'd probably have never created Groovy."[1] Strachan left the project silently a year before the Groovy 1.0 release in 2007."
