NetBeans has a message on its blog space about possibly integrating Grails at some point. Looking up what Grails is led me to look up Groovy- and it looks, well, kinda groovy. Granted, I've been looking it over for all of five minutes, but has anyone else heard of it? Have any good or bad stories? Is it something worth looking into further- given how vested I am in Java at this point- or should I stick with (eventually getting back to) Ruby?
