I recently came across Grails which appears to be a Java based RoR implementation of some sort I've got a couple questions plus would be interested in any general insight into using it with a new project.
It says it's written with Groovy, does that mean I'll be writing code in groovy? Will I be able to do most of the coding in Java?
What general advantages does groovy have over basic servlets or JSP what are the main features?
How easy have you found it to use?
