How will autotest see the application under test?

Hey.
How will autotest see the application under test?

My situation is very similar to mrif0393. (#45)
The only file related to the application under test is .jnlp.
There is application-desc main-class = "bo.Main" in .jnlp
The .jnlp file is on par with the autotest class

If you run only
application ("bo.Main"). start ();
That answer will be org.assertj.swing.exception.UnexpectedException: Unable to load class 'bo.Main'

If first I run .jnlp myself to see the UI, then the result is the same.

public static void start () {
         Desktop desktop = Desktop.getDesktop ();
         try {
             desktop.open (new File ("%some path%/file.jnlp"));
         } catch (IOException e) {
             e.printStackTrace ();
         }
     }
