Error executing a JavaFx jnlp

When I run my application from jnlp I get this error, but when I run it from IDE it does not give me problems.

public class AplicacionMipe extends Application {

@Override
public void start(Stage stage) throws Exception {


    Parent root2 = FXMLLoader.load(getClass().getResource("/aplicacionmipe/Inicio.fxml"));
    Scene scene2 = new Scene(root2);
    stage.setScene(scene2);
    stage.setResizable(false);
    stage.show();     
}

public static void main(String[] args) {
    launch(args);

}

this is the error:

    java.lang.NullPointerException: Location is required.
