According to Will it play in app engine you have to use grails app-engine run

umm scratch that.. running app-engine run used to blow up but now it does work in that the server comes up clean but I can't navigate to the app, it says "not found" if i hit localhost:8080/myapp, probably a config file, I'll investigate and let you know

A:
Localhost:8080 is your application. You do not need to add 'myapp' to your path.

A:
Agreed with tgd25 - you will need to remove /myapp that is why you are getting a 404.
Oddly enough, after having reached the same exception as you did with Grails 1.3RC1 on a Mac, I managed to get 'grails app-engine run' to startup with the DataNucleus enhancer and one (1) domain class just to test.
However, on a save, the webapp spews the following exception. See accompanying JIRA:

A:
I had to remove the tomcat plugin before mine worked. I think that's where the confusion comes in - tomcat serves the app at localhost:8080/appname whereas app engine plugin serves it off the root.
On my Mac with latest grails/appengine I couldn't get the current app-engine plugin [0.8.9] to work; I used the 0.8.8 version.
To run it, I just used "grails run-app".
Hope this helps.
good tip, I'll try the 0.8.8 version and let you know... I suspected some unhappy marriage of versions.
