    Default problem with applet

    I have problem with this applet. the browser gives page.I don't know wether its not loading or if its extremely slow.Also I am confused on the html part.Should I use tag object or applet and for entering class name data,classid or name.

    import java.lang.reflect.InvocationTargetException;
    public class NewJApplet extends javax.swing.JApplet {
        @Override
        public void init() {
            this.add(fesText);
            this.add(jButton1);
            this.add(jLabel1);
            this.add(jLabel2);
            this.add(jPanel1);
            this.add(jPanel2);
            this.add(msgText);
            this.add(jScrollPane1);
            try {
                java.awt.EventQueue.invokeAndWait(new Runnable() {
                    @Override
                    public void run() {
                        initComponents();
                    }
                });
            } catch (InterruptedException | InvocationTargetException ex) {
            }
        }
    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
            switch(fesText.getText().toLowerCase()){
                case "christmas":
                    msgText.setText("HAPPY CHRISTMAS");
                    break;
                case "diwali":
                    msgText.setText("HAPPY DIWALI");
                    break;
                default:
                    msgText.setText("ENTER VALID FESTIVAL");
                    break;
            }
        private javax.swing.JTextField fesText;
        private javax.swing.JButton jButton1;
        private javax.swing.JLabel jLabel1;
        private javax.swing.JLabel jLabel2;
        private javax.swing.JPanel jPanel1;
        private javax.swing.JPanel jPanel2;
        private javax.swing.JScrollPane jScrollPane1;
        private javax.swing.JTextArea msgText;
    html tag:-
    <!DOCTYPE html>
    <html>
    <head>
    <title></title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    </head>
    <body>
    <div><object data="JApplet.class" height="170" width="150"></object></div>
    </body>
    </html>

    Your classname is NewJApplet.

    See the tutorial: http://docs.oracle.com/javase/tutori...plet/html.html

    Are there any error messages in the browser's Java Console.

    Copy the html file and the class file(s) to a folder of your choice.

    what the tutorial is for,
    It's to help you understand how to write and execute an applet.

    If there are no error messages, it's hard to know what is wrong.

    Try opening the html file in the AppletViewer tool that comes with the JDK. See if it gives some messages.
    If you don't understand my answer, don't ignore it, ask a question.
