Problems with adding funds

Question

Hey guys , I have a problem with adding funds in my PSN account with my debit card . I have used the same card in the past with no problems at all but now for some reason it keeps on saying that the card number is invalid every single time ! Please help me , is there any solution ? Does it maybe has to do with Capital Control ( I live in Greece ) 

Answer 1

Thanks I use this
2.) You can make one of your buttons the default
button of the frame:
this.getRootPane().setDefaultButton(confirm);
well, did you implement the first suggestion of quitte?
here is an idea that might work!
JTextField username;
JPasswordField password;
JButton confirmButton;
   username.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent ae){
         password.requestFocus();                    
   ActionListener l = new ActionListener(){
      public void actionPerformed(ActionEvent ae){
         //optional check for username and password length>0
        //process logon.
   password.addActionListener(l);
   confirmButton.addActionListener(l);
