Yes, the idea is that the HTTPService returns HTTP data to Flex without reloading of the current page. You need to write a handler for the return of the HTTPService, and you should get a String containing the output of your S.O.println(). But that redirect does nothing for Flex. You can redirect based on the result you get from the login page, but that redirection must be done in the JSP that contains your original login MXML.
