Grails Helloworld tutorial app not working

I feel guilty coming to Stack Exchange with such a trivial issue, but I've been banging my head against it all morning and can't seem to get anywhere. I am trying to run the simple HelloWorld app in the Grails tutorial: http://grails.org/doc/latest/guide/gettingStarted.html#creatingAnApplication

I have Grails installed, I can run it, create the controller and everything, but no matter what page I hit, I get nothing but a blank. Even pages that don't exist, return a blank page and not an error.

For example, I tried http: //localhost:8080/helloworld, obviously, and get nothing but a blank page back. The same thing happens for http: //localhost:8080/hellowrld, http: //localhost:8080/helphelphelp and http: //localhost:8080/pleasefortheloveofpeteworkalready. Always the empty response.

When I try a different port, I get an error. When I stop-app and try, I get an error. When I run grails run-app with port 9090 and try port 8080, I get an error, but on 9090, I get the blank page. So, I assume the server is fielding the requests, but just isn't responding for some reason.

I'm probably missing something super simple, something dumb, but I can't figure out what it is, and the complete lack of feedback is killing me.

Are there logs anywhere I can check? And, is there something obvious I'm missing?

(PS: I assume the environment vars are correct, because I can run Grails no problem. Also, I installed, but never ran, the GGST IDE thing. I rebooted since then, but could that have installed some service that's taking over?)

Thanks, Peter

The application name is the default "context", so if you create an application called foo (grails create-app foo) it will be available at http://localhost:8080/foo if you run grails run-app. You can use a different port, for example 9090, by running grails -Dserver.port=9090 run-app and you can also use a different context (or none at all).

The run-app script displays the full URL of the application in the output window - you should see something like:

Server running. Browse to http://localhost:8080/helloworld
