To take advantage of the capabilities of modern browsers that use web standards， such as XHTML andCSS， your web application is being converted from simple JSP pages to JSP Document format. However，one of your JSPs， /scripts/screenFunctions.jsp， generates a JavaScript file. This file is included in severalweb forms to create screen-specific validation functions and are included in these pages with the followingstatement：
10.<head>
11.<script src='/scripts/screenFunctions.jsp'
12.language='javascript'
13.type='application/javascript'> </script>
14.</head>
15.<!-- body of the web form -->
Which JSP code snippet declares that this JSP Document is a JavaScript file？（）
A.<%@ page contentType=’application/javascript’ %>
B.<jsp:page contentType='application/javascript' />
C.<jsp:document contentType='application/javascript' />
D.
E.No declaration is needed because the web form XHTML page already declares the MIME type of the /scripts/screenFunctions.jsp file in the <script> tag.

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？（）
