To Create the helloworld Application

1. Change to the as-install/grails/samples directory.

2. Run the grails create-app helloworld command.

   The grails create-app command creates a helloworld application that you can modify.

To Create the hello Controller

1. Change to the as-install/grails/samples/helloworld directory.

2. Run the grails create-controller hello command.

   The grails create-controller command creates a controller file that you can modify in the /grails/samples/helloworld/grails-app/controllers directory:

3. Edit the generated HelloController.groovy file so that it looks as follows:

   class HelloController {
   
          def world = {
                   render "Hello World!"
           }
       //def index = { }
   }
