My applet will run just fine in the applet viewer, but not at all in my browser...

File is named Lab7.java
Code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.TitledBorder;


public class Lab7 extends JApplet implements ActionListener
{
	JTextField inputOne;
	JTextField inputTwo;
	JTextField outputOne;
	JButton accept;
	JButton exit;

	public void init()
	{
	    Container container = getContentPane();
    	container.setLayout(new BorderLayout());

		inputOne = new JTextField(10);
    	inputTwo = new JTextField(10);
    	outputOne = new JTextField(25);
    	accept = new JButton("Accept");

		outputOne.setEditable(false);

		JPanel p1 = new JPanel();
		p1.setLayout(new GridLayout(3,3));

		p1.add(inputOne);
		p1.add(inputTwo);
		p1.add(outputOne);
		p1.add(accept);
    p1.setBackground(Color.blue);
    p1.setBorder(new TitledBorder("Last Name then First Name"));

   	accept.addActionListener(this);

		container.add(p1,BorderLayout.NORTH);
	}

	public void actionPerformed(ActionEvent e)
	{
		if (e.getSource() == accept)
			outputOne.setText(inputOne.getText() + " " + inputTwo.getText());
	}
}
In my browser, I use this:
Code:
<HTML>
<APPLET CODE="Lab7.class" height = 400 width = 400></applet></HTML>
Any ideas?

Thanks!
