        codebase="http://localhost:8150/cargaApplet/" width=300 height=150 alt="esto no rula">
            <PARAM NAME="commonName" VALUE="Applet"/>
            <param name="email" value="applet@applet.com"/>
            <param name="idUser" value="16"/>
            <param name="activationCode" value="7"/>

      </applet>
   </body>
</html>
This is how I get the parameters in my class
 
 private void ObtenerValoresParametros() {
        System.out.println("before getParameter()");
        user.setName(getParameter("commonName"));
        user.setIdUser(getParameter("idUser"));
        user.setEmail(getParameter("email"));
        user.setActivationCode(getParameter("activationCode"));
        user.setRevocationCode(getParameter("revocationCode"));
        user.setOrganizacion(getParameter("organization"));
    }

not actually, in this case, it should return null!

looks like it is not properly initialized as applet!

ah, ok
I compile the jar, then I use an html to invoke it using a browser. The url is
http://localhost:8150/cargaApplet/cargaApplet.html
The jar is in the same directory as cargaApplet.html
