    Default 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}}
    at java.net.URLClassLoader.findClass(libgcj.so.90)
    at gnu.gcj.runtime.SystemClassLoader.findClass(libgcj .so.90)
    at java.lang.ClassLoader.loadClass(libgcj.so.90)
    at java.lang.ClassLoader.loadClass(libgcj.so.90)
    at gnu.java.lang.MainThread.run(libgcj.so.90)

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

    Thanks for your help.

    Default

    you can copy this code in your file TesBrowser.java

    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.
