as far as I know, the 'OK' button only has text.

can you post an example of one with the icon you want changed

Perhaps the look&feel adds an icon to that. In GTK for instance it's quite normal to have a little check icon (v) on the OK button, and an X on the Cancel button.

I've checked the source of JOptionPane and BasicOptionPaneUI, and I think you can do this by using the showOptionPane method, providing your own custom buttons to the method as the options. You'll need to handle which button was clicked manually. For instance:

JButton okButton = ...;
JButton cancelButton = ...;
Object[] options = {okButton, cancelButton};
int option = JOptionPane.showOptionDialog(..., options, cancelButton);
switch (option)
{
    case 0: // array index 0 so OK
        ...
        break;
    case 1: // array index 1 so Cancel
        ...
        break;
    case JOptionPane.CLOSED_OPTION: // dialog was closed through its titel bar
        ...
        break;
}

But in my case is showMessageDialog.
It's possible??

Thanks.

showMessageDialog, and all other methods, eventually delegate to showOptionDialog.

A part of JOptionPane's source:

public static void showMessageDialog(Component parentComponent,
    Object message) throws HeadlessException {
    showMessageDialog(parentComponent, message, UIManager.getString(
                "OptionPane.messageDialogTitle", parentComponent),
                INFORMATION_MESSAGE);
}

public static void showMessageDialog(Component parentComponent,
    Object message, String title, int messageType) 
    throws HeadlessException {
    showMessageDialog(parentComponent, message, title, messageType, null);
}

public static void showMessageDialog(Component parentComponent,
    Object message, String title, int messageType, Icon icon) 
    throws HeadlessException {
    showOptionDialog(parentComponent, message, title, DEFAULT_OPTION, 
                     messageType, icon, null, null);
}

Just use the same as the last one but with your custom options.
