You have built your own light-weight templating mechanism. Your servlets， which handle each request，dispatch the request to one of a small set of template JSP pages. Each template JSP controls the layout ofthe view by inserting the header， body， and footer elements into specific locations within the template page.The URLs for these three elements are stored in request scoped variables called， headerURL， bodyURL，and footerURL， respectively. These attribute names are never used for other purposes.
Which JSP codesnippet should be used in the template JSP to insert the JSP content for the body of the page？（）
A.<jsp：insert page=’${bodyURL}’ />
B.<jsp：insert file=’${bodyURL}’ />
C.<jsp：include page=’${bodyURL}’ />
D.<jsp：include file=’${bodyURL}’ />
E.<jsp：insert page=’<%= bodyURL %>’ />

B.<jsp：getProperty name="product" property="name" />
C.<jsp：useBean id="com.example.Product" /><%= product.getName（） %>
D.<jsp：getProperty name="product" class="com.example.Product" property="name" />
A session-scoped attribute， product， is stored by a servlet. That servlet then forwards to a JSP page. Thisattribute holds an instance of the com.example.Product class with a name property of "The Matrix" andprice property of 39.95. Given the JSP page code snippet： 1. 2.

Your IT department is building a lightweight Front Controller servlet that invokes an application logic objectwith the interface：public interface ApplicationController {public String invoke（HttpServletRequest request）}The return value of this method indicates a symbolic name of the next view. From this name， the FrontController servlet looks up the JSP URL in a configuration table. This URL might be an absolute path or apath relative to the current request. Next， the Front Controller servlet must send the request to this JSP togenerate the view. Assume that the servlet variable request is assigned the current HttpServletRequestobject and the variable context is assigned the webapp’s ServletContext.Which code snippet of the FrontController servlet accomplishes this goal？（）
