Attaching several buttons to one mouse listener

I have an application which consists of a GUI form, "EntryForm," and "DataForm," a collection of variables.
Clicking EntryForm's submit button sends the entries to DataForm.
The submit button is attached to a mouse listener "SubmitButtonHandler"

My Question: How can I attach an arbitrary number, up to five instances of EntryForm to ONE mouse listener?

I have tried this:

[code]
     final SubmitButtonHandler sbh = new SubmitButtonHandler( ...

     entryForm1 = new EntryForm();
     dataForm1 = new DataForm();
          entryForm1.submitButton.addMouseListener( sbh );
     entryForm2 = new EntryForm();
     dataForm2 = new DataForm();
          entryForm2.submitButton.addMouseListener( sbh );
     entryForm3 = new EntryForm();
     dataForm3 = new DataForm();
          entryForm3.submitButton.addMouseListener( sbh );
     entryForm4 = new EntryForm();
     dataForm4 = new DataForm();
          entryForm4.submitButton.addMouseListener( sbh );
     entryForm5 = new EntryForm();
     dataForm5 = new DataForm();
          entryForm5.submitButton.addMouseListener( sbh );
     ...
[/code]
In the mouse listener I have tried these approaches:

[code]
     public void mouseClicked( MouseEvent e ) {

          if ( e.getSource() == entryForm1.submitButton ) {
               System.out.println( "Clicked: entryForm1.submitButton" );
               // send the data to dataform1
          } else if( e.getSource() == entryForm2.submitButton ) {
               System.out.println( "Clicked: entryForm2.submitButton" );
               // send the data to dataform2
          } ...

     public void mouseClicked( MouseEvent e ) {

          if ( e.getSource() == submitButton ) {
               if( e.getSource() == entryForm1.submitButton ) {
               // send the data to dataform1
               } else if( e.getSource() == entryForm2.submitButton ) {
               // send the data to dataform2
               }
          } else if ( e.getSource() == anotherButton ) {
               ...
[/code]
In both cases, only ONE form's button registers and even that is screwy.

Can this approach be fixed so that the mous listener can discern between the various forms, or do I have to use five sets of forms and mouse listeners?

Many thanks in advance.

The first approach should work (assuming they are accessing the same variables).

WHat class are your submit buttons?
If they are Button's or JButton's then an ActionListener would be more appropriate than a MouseListener
