As mentioned in my previous piece I’ve been doing some prototyping using SpringSource’s Grails. Grails can be thought of as the top of the stack. If you pick up Grails you would naturally pull in the other pieces of SpringSource, including vFabric and ultimately vFoundry. In a future post I will deal with what happens when you stick Grails onto vFoundry, but at this stage I’ve been assessing the health of the SpringSource Ecosystem.
