This is my Swsmall file

public Swsmall() {
  JFrame frame = new JFrame ("Stand alone");
  JButton jl = new JButton("Exits properly");

  frame.getContentPane().add(jl);
  frame.setSize(180,80);
  frame.setVisible(true);



        jl.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
             System.exit(0);}});
            }

this my jsp file

<body>
    <applet code="TestApplet.class" width="400" height="400"></applet>
  </body>

I am able to run applet su开发者_如何学编程ccessfully but I can't get any responce on button click event

When I run same application on java console it works perfect

Calling System.exit(0) from Java applet will not destroy an applet. Try calling something else from action listener (i.e. System.out.println("something"); would print in Java applet console), and you'll see that it's called correctly, but in this case it probably doesn't work as you expected it to work.
