Problem on first usage

Thanks for this sample. When I tried to run it locally as per the README, it failed with:

    $ ./grailsw run-app

http://www.icodeya.com/2012/02/grails-javaiofilenotfoundexception.html suggested a solution which seemed to work. I've added that suggestion to the README in this pull request. This may be the wrong solution as I'm new to grails. You could try a fresh clone of the repo to see if the problem recurs for you.
