Has anybody JRuby for their webapp?
icey: I was using JRuby + Rails for some exploratory development very recently. It was pretty nice, the only complaint I had was the startup time when doing script/server... but really that wasn't all that bad either.If you've done much with Java, then it's really worth looking into JRuby. Also, Charles Nutter and the rest of the JRuby community are awesome.
