To take advantage of the capabilities of modern browsers that use web standards,such as XHTML and CSS, 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 several web forms to create screen-specific validation functions and are included in these pages with the following statement:
使用程式碼 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. <jsp:directive.page contentType='application/javascript' />
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.

jsp:directive.page 與 import 的區別

jsp:directive.page 與 import 的區別
<jsp:directive.page import=“zero.space.ch03.BookBean”/>
相當予
<%@ page import="zero.space.ch03.BookBean" %>
但是也有區別：
兩個用法的作用范圍不同，
<%@ page import="zero.space.ch03.BookBean" %> 可用於多個頁面內而
<jsp:directive.page import="zero.space.ch03.BookBean"/>只能用於一個頁面，不能跨頁調用。
例如：如果你把所有類別的引入放在一個JSP中，在其他jsp中用include引入那個jsp。
這時引入類就必須採用
<%@ page import="zero.space.ch03.BookBean" %> 這樣的寫法。
<jsp:directive.page import="zero.space.ch03.BookBean"/>
這種寫法只能在同一個jsp頁面中使用，不能跨頁週用...
