Java SE (Java Platform, Standard Edition)

Hello, I haven a applet embedded into a jsp page into an APPLET tag, with a fixed height and width, same values as the JPanel has on the applet with all the elements inside of it, my problem is, that if I use the browser zoom, the JPanel respects width and height but JApplet window does not, and increases until I stop zooming the site, I'd like to avoid this, I already tried by setting these parameters on the init function on the JApplet class:

this.setSize(593, 468);
this.setMaximumSize(new Dimension(593,468));
this.setMinimumSize(new Dimension(593,468));
this.setBounds(0, 0, 593, 468);
this.setPreferredSize(new Dimension(593,468));

But it does not work, is there something like a this.setResizable(false) for the JApplet class? I understand that JApplet is a subclass of JFrame isn't? please, any idea would be highly appreciated, have a nice day!!
