Insertar un api java en una web .class path

[dracola24]

Hola!

Incluso con este codigo tan sencillo:

Código HTML:

< applet code =
 'Ejs.Simulations._apps._examples.HVmin'
     archive = 'Ejs/Simulations/_apps/_examples/HVmin/hVmin.jar',
     width = 300, 
     height = 300 /> 

Tengo este error:
cargar: clase Ejs.Simulations._apps._examples.HVmin not found.
java.lang.ClassNotFoundException: Ejs.Simulations._apps._examples.HVmin

El problema es q no se como indicar la ruta hasta HVmin.class.
El fichero esta aqui:
C:\xampp\htdocs\blanca\Ejs\Simulations\_apps\_exam ples\HVmin

Alguna idea o ayuda??

Muchas gracias!
