Java Applet Error at Eclipse on Linux Ubuntu

Hi all,

I'm a newbie at Java. I'm try to learn about applet java using Eclipse (version 3.2.2) using java-1.5.0-gcj-4.3-1.5.0.0 at Linux Ubuntu 9.04

My script like this :
/*
Mencoba membuat applet di Eclipse linux Ubuntu
pada browser Mozilla Firefox
*/

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

public class TesBrowser extends Applet {
public void gambar (Graphics g) {
Font font = new Font ("Courier", Font.BOLD, 20);
g.setFont(font);
g.drawString("Gue lagi belajar Java Applet di Eclipse Ubuntu", 20, 30);
}

}

And my HTML script like this :
<html>
<body>
<APPLET code="TesBrowser" width="400" height="100">
</APPLET>
</body>
</html>

Both of them (java and HTML script) saved at same directory.

It can't be run well and show error message like this :
Exception in thread "main" java.lang.NoClassDefFoundError: sun.applet.AppletViewer
at gnu.java.lang.MainThread.run(libgcj.so.90)
Caused by: java.lang.ClassNotFoundException: sun.applet.AppletViewer not found in gnu.gcj.runtime.SystemClassLoader{urls=[file:/home/bytescode/Desktop/Materi Kuliah S2 Informatika ITB Teknologi Informasi/pemrograman dan aplikasi internet web/kuliah_web_programming/koding/BrowserApplet/], parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}

Help me, what's wrong with my script and or my java or eclipse?

Thanks for your help.

you can copy this code in your file TesBrowser.java

Code:

import java.applet.*; import java.awt.*; public class TesBrowser extends Applet { public void paint(Graphics g) { Font font = new Font ("Courier", Font.BOLD, 20); g.setFont(font); g.drawString("Gue lagi belajar Java Applet di Eclipse Ubuntu", 20, 30); } }

save it in, right-click the java-file and then Run As -> Java Applet. when all is ok, integrate it in your html-file.

Thanks you brother, now it can run well :D :D
