Problem with event handling

Question

Hello all,
I have a problem with event handling. I have two buttons in my GUI application with the same name.They are instance variables of two different objects of the same class and are put together in the one GUI.And their actionlisteners are registered with the same GUI. How can I differentiate between these two buttons?
To be more eloborate here is a basic definition of my classes
class SystemPanel{
         SystemPanel(FTP ftp){ app = ftp};
         FTP app;
         private JButton b = new JButton("ChgDir");
        b.addActionListener(app);
class FTP extends JFrame implements ActionListener{
           SystemPanel rem = new SystemPanel(this);
           SystemPanel loc = new SystemPanel(this);
           FTP(){
                   add(rem);
                   add(loc);
                   pack();
                   show();
       void actionPerformed(ActionEvent evt){
        /*HOW WILL I BE ABLE TO KNOW WHICH BUTTON WAS PRESSED AS THEY
           BOTH HAVE SAME ID AND getSouce() ?
           In this case..it if was from rem or loc ?
}  It would be really helpful if anyone could help me in this regard..
Thanks

Hi levi,
Thankx..
I solved the problem ..using same concept but in a different way..
One thing i wanted to make clear is that the two buttons are in the SAME CLASS and i am forming 2 different objects of the SAME class and then putting them in a GUI.THERE IS NO b and C. there is just two instances of b which belong to the SAME CLASS..
So the code
private JButton b = new JButton("ChgDir");
b.setActionCommand ("1");
wont work as both the instances would have the label "ChgDir" and have setActionCommand set to 1!!!!
Actually I have an array of buttons..So I solved the prob by writting a function caled setActionCmdRemote that would just set the action commands of one object of the class differently ..here is the code
public void setActionCommandsRemote()
     for(int i = 0 ; i <cmdButtons.length ; i++)
     cmdButtons.setActionCommand((cmdButtons[i].getText())+"Rem");
This just adds "rem" to the existing Actioncommand and i check it as folows in my actionperformed method
     if(button.getActionCommand().equals("DeleteRem") )          
                    deleteFileRemote();
      else if(button.getActionCommand().equals("Delete") )
                 deleteFileLocal();Anyway thanx a milion for your help..this was my first posting and I was glad to get a prompt reply!!!
