JFRAME applet works when run directly but not in web broeser

[sheetal7sheetal]

hey..I m using netbeans IDE 6.0.1 AND am trying to embed a jframe applet in the web project.I made a java project "Testing" and within it,a NewJFrame.java file with the following code:-
//made iN design mode....

package testing;
public class NewJFrame extends javax.swing.JFrame {

/** Creates new form NewJFrame */
public NewJFrame() {
initComponents();
}
private void initComponents() {

jButton1 = new javax.swing.JButton();

setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

jButton1.setText("jButton1");

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(layout.createSequentialGroup()
.addGap(141, 141, 141)
.addComponent(jButton1)
.addContainerGap(186, Short.MAX_VALUE))
);
layout.setVerticalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(layout.createSequentialGroup()
.addGap(130, 130, 130)
.addComponent(jButton1)
.addContainerGap(147, Short.MAX_VALUE))
);

pack();
}// </editor-fold>

/**
* @param args the command line arguments
*/
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new NewJFrame().setVisible(true);
}
});
}

// Variables declaration - do not modify
private javax.swing.JButton jButton1;
// End of variables declaration

}


..Then i made another web project "WebApplication2" and in index.jsp, i added within the body the following code:-
<applet code="testing.NewJFrame" archive="Testing.jar" codebase="." width=676 height=657></applet>

I also have included Testing.jar in "WebApplication2".But when i try to run index.jsp,
all the browsers give run time exception:-java.lang.reflect.InvocationTargetException/........
Although NewJFrame runs directly as applet.......but not in browser..kindly somebody help?

the thing is that wen i tried to do the same procedure with an applet which only displyed text "hello".........web browser showed the applet.but as soon as i add button or any such thing...it gives this exception...........
