Runtime class exec methods
If your Outlook executable is in different path ... import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Test2 extends JFrame implements ActionListener
   public Test2()
      super("Test");
      setDefaultCloseOperation(EXIT_ON_CLOSE);
      setSize(300, 200);
      JButton b = new JButton("Outlook Express");
      b.addActionListener(this);
      getContentPane().setLayout(new FlowLayout());
      getContentPane().add(b);
   public void actionPerformed(ActionEvent e)
      try{
         Runtime runTime = Runtime.getRuntime();
         Process proc = runTime.exec
                     ("C:\\Program Files\\Outlook Express\\msimn.exe");
         proc.waitFor();
      }catch(IOException ioe){System.out.println("Wham");}
      catch(InterruptedException ie){System.out.println("Bop");}
   public static void main(String[] args)
      new Test2().setVisible(true);
}
