ActionForm form, HttpServletRequest request, HttpServletResponse response ) throws Exception{ // Get the user’s login name and password. They should have already been// validated by the ActionForm. String email = ((LoginForm)form).getEmail( ); String password = ((LoginForm)form).getPassword( ); // Obtain the ServletContextServletContext context = getServlet().getServletContext( ); // Log which user is trying to enter the site context.log( “Login email: ” + email ); // Log in through the security serviceIStorefrontService serviceImpl = getStorefrontService( ); UserView userView = serviceImpl.authenticate(email, password); // Log the UserView for auditing purposes context.log( userView.toString( ) ); UserContainer existingContainer = null; HttpSession session = request.getSession(false); if ( session != null ){ existingContainer = getUserContainer(request); session.invalidate( ); }else{ existingContainer = new UserContainer( ); } // Create a new session for the user session = request.getSession(true); existingContainer.setUserView(userView); session.setAttribute(IConstants.USER_CONTAINER_KEY, existingContainer); return mapping.findForward(IConstants.SUCCESS_KEY); } } The LoginActionin Example 15-1 shows a very simple example of sending log messages to the container’s log file. It calls the log( ) method and passes a literal string message that will be written to the log. As was mentioned earlier, the name and location of the log are dependent on which web container is being used.
