Disable the text field of JFileChooser

Currently, I've been trying to disable the JTextField of a JFileChooser that I am working.

At first blush I thought: "piece of cake"

Unfortunately, the Java Standard API does not implement it. So I've tried something like this to reach my goal.

Components[] comp = myJFileChooser.getComponents();
for(Component c: comp) {
if(c instanceof JTextField) {
c.setVisible(false);
}
}

It didn't work out.

But, the following idea worked :)

Indeed the dificulty of this problem is to get the reference of the target JTextField. A single call of myJFileChooser.getComponents() is not enough because the text field is not directly involved by the JFileChooser.
