Notice how only five rows and part of the sixth are visible. By pressing the up/down buttons on the D-pad, you can scroll up and down to see the remaining rows. Also note how the right side of the content is clipped by the scrollbar. Be sure to put some padding on that side or otherwise ensure your content does not get clipped in this fashion. Android 1.5 introduced HorizontalScrollView, which works like ScrollView, but horizontally. This can be useful for forms that might be too wide rather than too tall. Note that neither ScrollView nor HorizontalScrollView will give you bidirectional scrolling; you need to choose vertical or horizontal.

Programmer: But that doesn t explain what s actually wrong with the design just that something might not be right. Reviewer: Well, then, let s follow the breadcrumbs. We need to find out where the ID and the bookDao come from. Clue number 2: You re setting the ID on the Book. But the Book is our Spring command object, and the ID should be set automatically for us because it s passed in via the web request. But and this is clue number 3 this isn t shown on the diagram. We also need to show the bookDao being set. And finally, clue number 4: It isn t actually the DispatcherServlet class that creates the Command object. Programmer: I know, it s actually ServletRequestDataBinder, one of Spring s helper classes. But we ve generally used DispatcherServlet to mean some Spring class or other it s a black box. Reviewer: Sometimes it s probably OK to do that. But in this case, glossing over the details like that means that you missed a detail.

didn t exist, the user would be redirected to a login page, where the cookie would be created after a successful login. ASP.NET uses the same approach in its forms authentication model. You are still responsible for creating the login page (although you can use a set of specially designed controls to help you, as described in 19). Best of all, you don t need to create the security cookie manually, or check for it in secure pages, because ASP.NET handles these tasks automatically. You also benefit from ASP.NET s support for sophisticated validation algorithms, which make it all but impossible for users to spoof their own cookies or try other hacking tricks to fool your application into giving them access. Figure 18-4 shows a simplified security diagram of the forms authentication model in ASP .NET.

To implement forms-based security, you need to follow three steps: 1. Set the authentication mode to forms authentication in the web.config file (or use the WAT). 2. Restrict anonymous users from a specific page or directory in your application. 3. Create the login page.

You define the type of security in the web.config file by using the <authentication> tag. The following example configures the application to use forms authentication by using the <authentication> tag. It also sets several of the most important settings using a nested <forms> tag. Namely, it sets the name of the security cookie, the length of time it will be considered valid (in minutes), and the page that allows the user to log in.
