Hi, I´m doing one aplication gwt where I need a log for I go doing traces, but my problem is the next:

I don´t know where the applicacion leave the report log for afterward I look it and I see that the aplication has wrote.
I´m using IDE: Netbeans and my code is this:

//section import
import com.allen_sauer.gwt.log.client.Log;

//start class
public class Prueba implements EntryPoint {
   ...
public void onModuleLoad() {
       
        //Declaro el recinto
        final DrawingArea canvas = new DrawingArea(1024, 768);
        final Circle circulo = new Circle(512, 50, 30);
        circulo.setFillColor("red");
        final Pulsada pulsada = new Pulsada();
        //se crean los círculos nuevos
        final Circle c1 = new Circle(256, 150, 30);
        final Circle c2 = new Circle(512, 150, 30);
        final Circle c3 = new Circle(768, 150, 30);
        c1.setFillColor("green");
        c2.setFillColor("green");
        c3.setFillColor("green");
        //se crean las nuevas líneas que unirán los nodos
        final Line l1 = new Line(circulo.getX(), circulo.getY(), c1.getX(), c1.getY());
        final Line l2 = new Line(circulo.getX(), circulo.getY(), c2.getX(), c2.getY());
        final Line l3 = new Line(circulo.getX(), circulo.getY(), c3.getX(), c3.getY());
        circulo.addClickHandler(new ClickHandler() {
            public void onClick(ClickEvent event) {
                if(!pulsada.isHaSidoPulsado()){
                    ConsoleLogger cl = new ConsoleLogger();
                    Log.info("pulso el primero nodo");
                    ...
               }else{
                    ...
                    Log.info("pulso otra vez el primero nodo para borrar");
                    canvas.remove(c1);
                    canvas.remove(c2);
                    ...
               }
...
}

Thanks.
