No applet html file produced.

It works well in netbean, a snapshop is created. But I didn't see any applet html file in the folder c:\...\build\class

The xxx.html launcher file in the build folder is never found.

Please help me. I just followed the simple example of the link,but no MyApplet.html is generated.

But I didn't see any applet html file in the folder c:\...\build\classAre you sure you are looking in the right place. The tutorial shows the applet html file will be created in the build directory and not the class subdirectory.

Note: it will only be called MyApplet.html if your applet class is called MyApplet.class

keang, I tried a simple example, it doesn't work.
I use Netbeans and follow the link.
http://www.netbeans.org/kb/50/tutorial-applets.html#runanddebug
After I created MyApplet.jar in the dist folder,

Failed to load Main class manifest attibute from
C:\Documents and Settings\...\MyApplet.jar



Here is the code

package org.me.hello;

import java.applet.Applet;
import java.awt.Graphics;

public class MyApplet extends Applet {
public void paint(Graphics g) {
g.drawString("Hello applet!", 50, 25);
}
}

The NetBeans Applet Tutorial is correct but more than a little confusion. Took me half an hour to figure it out.

Where it says "Right-click the applet class node in the Projects window and choose Run File from the contextual menu" what you have to do is:

1) click the "Projects" tab
2) locate "MyApplet.java"
3) right click that one and select "Run File" ("Run Project" is something different)

After that the MyApplet.html is generated. You will see it under the "Files" tab.
