I can't run my applet program on browser why?

Just want to try running applet on my browser, so I made a simple program:

import java.awt.*;
import javax.swing.*;

public class NotHelloWorldApplet extends JApplet {
    public void init() {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                JLabel label = new JLabel("Hello World applet",    SwingConstants.CENTER);
                add(label);
            }
        });
    }
}

And here is my HTML file:

<html>
    <head>
        <title> Hello World Applet</title>
    </head>
    <body>
        <applet code=“HelloWorldApplet.class” width=“300” height=“300”>
        </applet>
    </body>
</html>

And here is my browser configuration: Java plugins

Everything looks great, but when I run my HTML file, it doesn't work. It simply show the content: Applets

I can view it on Eclipse, just cannot view it on the browser. Is there anything I made it wrong?

Solution

  • Ok, when I open the HTML file on Dreamweaver, the HTML file oddly appear lots of extra lines. I don't know why, but I made the HTML file via TextEditor in the first place, I guess it is just not a qualified "HTML editor". Therefore, I redo a HTML file on Dreamweaver, and it works. Lesson learned, don't trust TextEditor to make a HTML file, because it might have some hidden content.
