The web client in this example is a standard JSP page, and annotations are not used in JSP pages because JSP pages are compiled as they are presented to the browser. Therefore, none of the code that adds form-based authentication to the example is included in the web client. The code for the JSP page used in this example, hello1_formauth/web/index.jsp, is exactly the same as the code used for the unsecured JSP page from the example application at tut-install/javaeetutorial5/examples/web/hello1/web/index.jsp.
The information that adds form-based authentication to this example is specified in the deployment descriptor. This information is discussed in Specifying a Security Constraint.
