JSP Actions Quiz

Answer the following questions and click 'Mark Test' when finished to see how well you did.

1. Which of the following can the JSP include action include output from ?
   Another JSP
   Plain text file
   CGI Program
   Servlet
   All of the above
   
    

2. The <jsp:include/> action can pass parameters to the page which it is including. How does this second page obtain the value of these parameters ?
   Using the <jsp:readParam/> action
   Using the <jsp:getParam/> action
   Use the request.getParameter() method
   Use the response.getParameter() method
   
    

3. What is wrong with the following code ?

   <%
   if(strPassword.equals("boss"))
   {
     <jsp:forward page="Welcome.jsp" flush="true"/>
   }
   else
   {
     <jsp:forward page="Login.jsp" flush="true"/>
   }
   %>
   

   Unmatched bracket in for statement
   Flush attribute must be false
   Keyword 'file' should be used instead of 'page' in the <jsp:forward/> action
   Actions cannot be used within scriptlet blocks
   
    

4. What is wrong with the following code ?

   <jsp:include page="MainMenu.jsp" flush="true"/>
   <%
   Cookie c = new Cookie("UserName", "Alastair Gulland");
   response.addCookie(c);
   %>
   

   Cookie class can not take parameters in it's constructor
   The request object is used for creating cookies
   Although no error will be reported the use of the <jsp:include/> action means that the response object can't be used to create cookies.
   The <jsp:include/> action must be placed inside the script block
