Bom dia pessoal, fiz todos os passos para assinar a applet a seguir. Segui esse tutorial: http://insonix.blogspot.com.

minha class

import java.applet.Applet;

public class AppletTeste extends Applet {

    private String xmlPath;

    @Override
    public void init() {
	String usuario = System.getProperty("user.name");
	String usuarioHome = System.getProperty("user.home");

	System.out.println("Usuario Home " + usuarioHome);
	System.out.println("Usuario " + usuario);

    }

    public String getUsuario() {
	String usuario = System.getProperty("user.name");
	return usuario;
    }
}

meu html:


<html>
<head>
<title>Login User</title>
</head>
<body>
<APPLET CODE="AppletTeste.class" archive="AppletTeste.jar" WIDTH=300 HEIGHT=250>
</APPLET> 

</body>
</html>

e aqui vem o error:

java.security.AccessControlException: access denied (java.util.PropertyPermission user.name read)
	at java.security.AccessControlContext.checkPermission(Unknown Source)
	at java.security.AccessController.checkPermission(Unknown Source)
	at java.lang.SecurityManager.checkPermission(Unknown Source)

	at java.lang.Thread.run(Unknown Source)
Exception: java.security.AccessControlException: access denied (java.util.PropertyPermission user.name read)
