For some reason the class file is not shown in the project's "build"-directory (the directory seems to be empty instead). Anyhow outside of Eclipse from Windows' file system you can see that the file "TestApplet.class" really is in directory "TestProject/build/classes". The html file "TestHTML.html" is placed in "WebContent". To make sure that the two files are close enough, I copy-pasted the class file into WebContent-folder, but there was no change.
I added some System.out.println-lines to the javacode to see if it writes anything to the console (I guess this can be done in web-projects, too?) Well, there was no output. I also changed the width and height parameters in the html file to see if that produces any effect, and it does. So it seems that parameters in the html are ok but for some reason the javacode doesn't execute. But why?

Hi have tried web application exactly like above problem,
Now I am really in trouble, Please help me ASAP.
I have created two class 1) Card.java and 2) cardDemo.java(It's Applet) in eclipse and create htmi page index.html in webcontent folder, now I am trying to run this applet in html form its gives a Application Error, I have also tried paste classes folder in WEB-INF and change path applet tag, but not working.
Now my CardDemo and Card class is related ,bellow is the code,
CardDemo.java:-
package com.progresso;
