4. Your web application uses a simple architecture in which servlets handle requests and then forward to a JSP using a request dispatcher. You need to pass information calculated in the servlet to the JSP for view generation. This information must NOT be accessible to any other servlet, JSP or session in the webapp. Which two techniques can you use to accomplish this goal? (Choose two.)
A) Add attributes on the request object.
B) Add attributes to the session object.
C) Add parameters to the JSP's URL when generating the request dispatcher.
D) Add parameters to the request object.
E) Use the pageContext object to add request attributes.
5. Given this fragment in a servlet:
23.
if(req.isUserInRole("Admin")) {
24.
// do stuff
25.
}
And the following fragment from the related Java EE deployment descriptor:
812.
<security-role-ref>
813.
<role-name>Admin</role-name>
814.
<role-link>Administrator</role-link>
815.
</security-role-ref>
900.
<security-role>
901.
<role-name>Admin</role-name>
902.
<role-name>Administrator</role-name>
903.
</security-role>
What is the result?
A) If line 24 executes, the user's role will be Admin.
B) The deployment descriptor is NOT valid.
C) Line 24 can never be reached.
D) If line 24 executes the user's role will NOT be predictable.
E) If line 24 executes, the user's role will be Administrator.
