Well, when I'm prototyping and generally developing with grails I do not want to use generate-all and just edit the generated controllers and gsps. I try to find my way overwriting maybe some actions but not edit them and some or more changes to the scaffold templates.
After having static resources get served right with Jetty within an OSGI enviroment you may want to be able to use groovy and more specific some groovlets
More or less the problem is the one that has been described at a previous post. Once again all we have to do is give some more "space" to the
groovy.servlet.GroovyServlet to look for our groovlets
