JButton and Command Pattern help URGENT

[gavo87]

Hi,

I am making a GUI which implements a command pattern that will output a simple message saying "hello". I have a class Client within a package gmit. I have a button called connect which does the following:
class connect implements ActionListener{

public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
Command command = (Command)e.getSource();
command.run();

}

}

every time i press the button i get the following error:
Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: javax.swing.JButton cannot be cast to gmit.Command
at gmit.Client$connect.actionPerformed(Client.java:57 ).

could someone please help me...

The error is telling you what you're doing wrong. e.getSource returns the JButton object, and you can't use this as a Command object (whatever that is). You'll have to find another way to get the reference to your Command object, and we can't help you with this given the information presented so far. If you need more help, you'll need to give us more information including code with code tags please.
