AppletViewer - "applet not initialized"

java applet awt paint appletviewer
Rick_Sch picture Rick_Sch · Jun 17, 2013 · Viewed 16.1k times · Source

My code compiles and works just fine in both my browser and Eclipse, but for some reason the AppletViewer just won't work with my VERY simple code. When I try to run it with appletviewer FirstApplet.html, the AppletViewer window appears as expected, but the upper-left part of the window just says "Applet" and the bottom-left part of the window says "Start: applet not initialized"

What could be the problem here? (Again, it works in my browser and Eclipse)

Thank you for any help! :)

FirstApplet.java

import java.awt.*;
import java.applet.*;

public class FirstApplet extends Applet {
    public void paint(Graphics g){
        g.drawString("This is my first Java Applet!", 20, 30);
    }
}

FirstApplet.html

<html>
    <head>
        <title>FirstApplet</title>
    </head>

    <body>
        <applet
            codebase    = "."
            code        = "FirstApplet.class"
            name        = "FirstApplet"
            width       = "640"
            height      = "480"
            hspace      = "0"
            vspace      = "0"
            align       = "middle"
        >

        </applet>
    </body>
</html>

I figured it out! It was an Eclipse problem after all!

I wrote and compiled the code in Eclipse. Eclipse's internal version of the AppletViewer worked just fine, and it worked just fine to open the HTML file that I made in my browsers.

The applet didn't work in the actual AppletViewer, however, until I compiled the code using something other than Eclipse. It appears that for some reason AppletViewer didn't like the .class file that Eclipse generated.

Mystery solved!
