I don't have any idea what could have caused this. The application ran the other day, but not today. I have added code the project, but none of it is actually used. The application is pretty much hello world. (I've only started playing with jetgroovy and grails.)
I updated to the 1.1beta, but have the same result. The class GroovyStarter does indeed exist. What can I do to track down the problem? Thanks!
