I have used the GeneralPath Class to draw a path, but nothing appears on the screen...
If I draw with the Line2D Class everythings seems to be fine...
Does anyone sees some failure in my Code ? :

class CurvePanel extends JPanel {

GeneralPath path = new GeneralPath();

public CurvePanel() {
setBackground(Color.white);
}

protected void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2 = (Graphics2D)g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
g2.draw((Shape)path);
}

public void addCurve(Vector v) {
int[] x = new int[v.size()+1];
int[] y = new int[v.size()+1];
int i = 0;

for (Iterator iter = v.iterator(); iter.hasNext() {
Point p = (Point) iter.next();
x[i] = (int) p.getX();
y[i] = (int) p.getY();
i++;
}

for(int u=1;u<i;u++) {
path.moveTo(x[u], y[u]);
}
repaint();
}
}

Even if I close the Path, there is no effect.
DoI have to close my Path?
