Java SE (Java Platform, Standard Edition)

Hi All,

I have a JButton on the JPanel.So when i click on the button i get one frame which contains many setting parameters required for my application.But the problem when i click on the same 20 times i get 20 windows of my settings in the same case till n times.So i have used boolean flag variable and cleared the problem.

Now my question i am doing the same mechanism with one more JButton like this

JButton mailToItem=new JButton("DROPMAIL");
 mailToItem.addActionListener(new OnDropAMail());

class OnDropAMail implements ActionListener{
	
public void actionPerformed(ActionEvent mailEvent) {
        try {
			if ( mailEvent.getSource()==mailToItem ){
	  	JTextField maillabel=new JTextField("mailTo:queryforall@gmail.com");	
		maillabel.setEditable(false);
          URI mailURI = new URI(maillabel.getText());
		  
		  desktop.mail(mailURI);
		  
		 // checkdropmail=false;
		 // QueryMailing.main(call);
            }        } catch (Exception ex) {
          System.out.println(ex.getMessage());
        }
                   }
}

So in the above code problem is when i click on the same DROPMAIL button continuously i am getting many outlook express windows since my default email client in my local machine is Outlook.So how should i control that Outlook JFrame so that after me closing the JFrame it has to be activated for opening it next time.Some kind of validation has to be authenticated.

Any help Appreciated.

Thanks in advance.

regards,
Viswanadh
