        Here is an example of a class implementing PrivilegedAction:

   public class TestAction implements java.security.PrivilegedAction {

      public Object run () {
                        System.out.println("You are supposed to do some controlled " +
                "action like getting a system property (user.home = " +
                                System.getProperty("user.home") + ")";
                }

   }
