Try to use this in you paint method :
public void paint(Graphics g)
Graphics2D g2D = (Graphics2D) g;
// Get the height & width
int width = this.getWidth();
int height = this.getHeight();
// Create the gradient paint
gradientPaint = new GradientPaint(0,0, Color.blue, width, height, Color.red);
g2D.setPaint(gradientPaint);
g2D.fillRect(0,0, width, height);
