The setup and lifecycle for this PhaseListener are as described in 12 In this case, we want to take action during the beforePhase( ) event of the RenderResponse lifecycle phase The real work of the beforePhase( ) method takes place only if this run through the lifecycle is for a postback request that passed through the decode( ) method of the RememberMeLoginComponent Recall that this method stored a reference to the RememberMeLoginComponent instance in the RequestMap Here, the existence of that

instance in the Map is checked If it is not present, no action is taken If it is present, the static checkLoginState method of the ForcedLoginFilter component uses the Virtual Trainer s login scheme to check if the login was successful If so, the next step determines if the user checked the checkbox, indicating their desire to have the login information remembered If so, the user ID and password are extracted from the components and set as the value of a cookie Otherwise, an empty cookie is created In all cases, a cookie is added to the response This is necessary because the Servlet API provides no way to remove a cookie from the browser s cookie store, so if the user decides they want to have the system forget the cookie value, the best we can do is clear out sensitive information from the cookie s value
Leveraging JAAS from a JSF Application
We will conclude this chapter by showing how to enhance the Virtual Trainer example by leveraging the standard security infrastructure of the Java platform From its inception, the Java platform has treated security as a first-class concern Indeed, one of the first benefits of Java was to securely bring dynamic behavior to Web-deployed applications Over the years, the implementation and API to security has evolved, but the core principals have improved and become steadily more secure Therefore, choosing to build your application-managed security on top of the standard Java security features is a very safe bet A term often applied to Java security is JAAS, which is short for Java Authentication and Authorization Service JAAS started out as an optional package in JDK 13 but has become a core part of the Java platform as of JDK 14 As the name implies, JAAS covers the first two of the three main aspects of security: authentication and authorization Let s explore one way to integrate JAAS-style authentication and authorization into the Virtual Trainer application
