NO.1 A developer is building an application where the home page will have links displayed
for administrators,
which will not be available for regular users of the application. Otherwise, the home page is
identical for
administrators and regular users. A J2EE role-based security pattern is being implemented
with one role
for users and one role for staff. What is the BEST way to display different versions of the
home page?
A. You map the two roles to different JSPs for the home page, where one includes the extra
links (for
administrators) and the other does not (for users).
B. It is not possible to display different versions of the same page for users who have
different roles.
C. You apply declarative security to the body of the JSP where the links that are only
available to the
administrators are declared to be accessible only to that role.
D. You implement the links using a J2EE custom library, which contains a call to
isUserInRole() on the
HttpServletRequest to see if the link should be displayed or not.
