Load a JFrame into a html

I am trying to open my Applet.jar in a html code.

My Java code is :

public class NewJFrame extends javax.swing.JFrame {

    public NewJFrame() {
        initComponents();
    }

    private void initComponents() {
        setTitle("Example");
        //more lines code base in JFrame with button,labels etc
    }

    public static void main(String args[]) {
        try {
            for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(info.getName())) {
                    javax.swing.UIManager.setLookAndFeel(info.getClassName());
                    break;
                }
            }
        } catch (ClassNotFoundException ex) {
            java.util.logging.Logger.getLogger(NewJFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (InstantiationException ex) {
            java.util.logging.Logger.getLogger(NewJFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (IllegalAccessException ex) {
            java.util.logging.Logger.getLogger(NewJFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        } catch (javax.swing.UnsupportedLookAndFeelException ex) {
            java.util.logging.Logger.getLogger(NewJFrame.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
        //</editor-fold>

        /* Create and display the form */
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new NewJFrame().setVisible(true);
            }
        });
    }
}

My html code is :

<!DOCTYPE html>
<html>
<body>

<h1>Java Applet Example</h1>

<p><object type="application/x-java-applet" width="300" height="300"> <param name="code" value="NewJFrame.class" /> <param name="archive" value="20130717_Applet.jar" /> <param name="mayscript" value="true" /> Java failed to load </object></p>

</body>
</html>

So when i am trying to open the html file with a browser it throws me up :

Java Error: “ClassNotFoundException NewJFrame.class”

I change the security for the java control panel to Medium from High but i get the same error.

AFAIK a class needs to extend one of the applet classes to run the class as an applet. 

public class NewJFrame extends javax.swing.JApplet {

Since applets do not provided a setTitle method (at least not directly), comment out the line

setTitle("Example");

To run the application directly using a JFrame, Java Web Start could be used
