Insert API in a web page .class path

Question

Hi!

I would like to insert an API java into a web page.

Even with such an easy code:

applet code = 'Ejs.Simulations._apps._examples.HVmin'

archive = 'Ejs/Simulations/_apps/_examples/HVmin/hVmin.jar',

width = 300, 
height = 300 />

I get this error:
cargar: clase Ejs.Simulations._apps._examples.HVmin not found. java.lang.ClassNotFoundException: Ejs.Simulations._apps._examples.HVmin at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.io.IOException: open HTTP connection failed:http://localhost/blanca/Ejs/Simulations/_apps/_examples/HVmin.class at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Excepción: java.lang.ClassNotFoundException: Ejs.Simulations._apps._examples.HVmin

I don't know where to put HVmin.class, I have tryed in differents paths with the same result.

The file HVmin.class is in this path: C:\xampp\htdocs\blanca\Ejs\Simulations_apps_examples\HVmin

Any help, please??

Thanks in advance
