Using the @ServletSecurity annotation in JavaEE 6

Shing Wai's post explains the @ServletSecurity annotation that has been introduced newly in JavaEE 6 (Servlet 3.0 specification). The @ServletSecurity annotation provides an alternative mechanism for defining access control constraints equivalent to those that could otherwise have been expressed declaratively via security-constraint elements in the portable deployment descriptor. There is also a Programmatic approach for adding security (via ServletRegistration.Dynamic API) that has been introduced newly in JavaEE 6, i will talk about it in another post. Using the @ServletSecurity annotation one can now have a descriptor free secure WebApplication in Glassfish V3. And using the fact that the default mode in calls to enterprise beans from web applications is for the security identity of a web user to be propagated to the EJB container, we can actually have a secure enterprise application without any security information in the portable deployment descriptors. So let us define an example Servlet which invokes a Secure EJB (A currency converter bean). The ServletSecurity annotation on the servlet below is such that any authenticated user in role "TutorialUser" or "guest" is allowed access to the Servlet. However the Converter EJB would only allow a user in role "TutorialUser" to access its methods. The ServletSecurity annotation below is equivalent to the following element. /TutorialServletBASIC TutorialUser guest pa...
