Applet works in applet viewer, not in browser

[aescott]

I'm running NetBeans 6.5.1 on openSuse 11.0 32 bit (if that helps).

I'm planning on deploying a java program as a web tool, but thought I ought to have a go at a simple applet first. Good idea, because it doesn't work....

The applet works in the applet viewer; however, I get an error with the browser.

Here is the applet code:

You should add an "init" method to your applet. That's the method that gets called when the applet starts. I think that's what it is complaining about.

Here is the applet code:




Code:
package WebTest;



import javax.swing.JApplet;

import java.awt.Graphics;



public class HelloWorld extends JApplet

{

public void paint(Graphics g)

{

g.drawRect(0, 0, getSize().width -1, getSize().height - 1);

g.drawString("Hello, World!", 5, 15);

}

}







...and here is the output from the Console:




Code:


java.lang.NoClassDefFoundError: HelloWorld (wrong name: webtest/HelloWorld)

Exception: java.lang.NoClassDefFoundError: HelloWorld (wrong name: webtest/HelloWorld)







Can anyone tell me what I'm doing wrong? I expect it's something really basic.

Thanks in anticipation.

Your problem is probably in the HTML, as the error mention webtest/HelloWorld and I doubt that your class is inside a package named webtest, which is probably the name of the project, not the package. Check your applet tag in the HTML file.

Aescott, did you ever solve this issue? I am having a similar issue and it is frustrating to say the least. Thanks.
