Angular 2 systemjs - angular, systemjs

No entiendo muy bien el sistema. Tengo problemas al intentar importar por Angular.

Funciona bien

Import {UtilClass} from "./shared/util.class";

Tengo un componente en otra carpeta pero si intento cargarlo

Import {UtilClass} from "../shared/util.class";

Tengo el siguiente error y al verificar en el registro los archivos cargados, lo que observo es que no está poniendo la extensión js cuando uso "../" / util.class 404 (no encontrado)

(function (global) {

var staticPath="src/";

var paths = {
// paths serve as alias
"npm:": "https://unpkg.com/"
};

// map tells the System loader where to look for things
var map = {
"app": "app",
// angular bundles

System.config(config);
})(this);

Cuando la ruta es relativa se produce este error, supongo que hay una mejor manera de corregirlo.

var packages = {
"app": {
main: "../.." + staticPath + "/main",
defaultExtension: "js",
defaultJSExtensions: true
}
,
"rxjs": {
defaultExtension: "js"
}
};
//I added this and works
packages["./../.."+staticPath+"/"]={main:"main",defaultExtension: "js"}
