get data json file for angular js app-in-app in grails directly

hi i want to access my json data file in my angular app inside an app in grails. i dont find any way to address the json file clientside. in the tutorial the databinding is only cocered for json data so this is crucial for me.

function ShitCtrl($scope, $http) {

  $http.get('http://localhost:8080/webapp/clients.json').success(function(data) {
    $scope.shits = data;
  });
}


function ShitDetailCtrl($scope, $routeParams) {
  $scope.shitId = $routeParams.shitId;

}

this reports an 404 error. how can i solve this issue? when i address it in urlMappings this does not work then the mappings are absolute.

the point is: grails maps everything based on urlMappings, so it is not possible to address a file directly from js.

config . groovy: 

grails.resources.adhoc.patterns = [
        '/images/*',
        '/css/*',
        '/js/*',
        '/plugins/*',
        **'/staticData/*',**
        '/assets/*'

so this then works like a charm:

function ShitCtrl($scope, $http) {
  $http.get('../static/staticData/clients.json').success(function(data) {
    $scope.shits = data;
  });
}
