Cannot get MAP to work in system.config packages for SystemJS

Question

Hello, I have the following configuration setting for systemJS:

    System.config({
    packages: {
        //sets the root path of the Angular2 App
        'DesktopModules/RegentDMS/app': {
            //module format expected in application, register = System.register or System.registerDynamic compatibility module format
            format: 'register',
            //default file extension for paths
            defaultExtension: 'js',
            map: {'./app' : './DesktopModules/RegentDMS/app'}
        },
    } 
  }); 
System.import('app/boot')
        .then(null, console.error.bind(console));

The default extension works fine, but I get a 404 error in the console, which reads:

GET http: // localhost: 81 / app / boot 404 (not found)

But if I change it to the following:

    System.config({
    packages: {
        //sets the root path of the Angular2 App
        'DesktopModules/RegentDMS/app': {
            //module format expected in application, register = System.register or System.registerDynamic compatibility module format
            format: 'register',
            //default file extension for paths
            defaultExtension: 'js'
        },
    } 
  }); 
System.import('/DesktopModules/RegentDMS/app/boot.js')
        .then(null, console.error.bind(console));

Then it works.

Question:

how to configure the MAP option so that I can use the short application / reference the absolute path to DesktopModules / RegentDMS / app in import operations like app / boot (which means DesktopModules / RegentDMS / app / boot. JS)

thanks

EDIT # 1:

So I changed. / app on the application, as suggested, and tried both of the following:

 map: { 'app': './DesktopModules/RegentDMS/app' }
 map: { app: './DesktopModules/RegentDMS/app' }

and this does not work when using any of the following import statements:

System.import('app/boot')
 System.import('./app/boot')

:

http://localhost:81/app/boot 404 ( )

:

:

    System.config({
    packages: {
        //sets the root path of the Angular2 App
        'DesktopModules/RegentDMS/app': {
            //module format expected in application, register = System.register or System.registerDynamic compatibility module format
            format: 'register',
            //default file extension for paths
            defaultExtension: 'js'
        }
    },
    map: { 'app': './DesktopModules/RegentDMS/app' }
  }); 
System.import('app/boot')
        .then(null, console.error.bind(console));
