单选题Your web application views all have the same header， which includes the  tag in the  elementof the rendered HTML. You have decided to remove this redundant HTML code from your JSPs and put itinto a single JSP called /WEB-INF/jsp/header.jsp. However， th

第1题：

Every page of your web site must include a common set of navigation menus at the top of the page. Thismenu is static HTML and changes frequently，so you have decided to use JSP’s static import mechanism. Which JSP code snippet accomplishes this goal？（）

第2题：

You have created a JSP that includes instance variables and a great deal of scriptlet code. Unfortunately，after extensive load testing， you have discovered several race conditions in your JSP scriptlet code. To fixthese problems would require significant recoding， but you are already behind schedule. Which JSP codesnippet can you use to resolve these concurrency problems？（）

• A、<%@ page isThreadSafe=’false’ %>
• B、<%@ implements SingleThreadModel %>

第3题：

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}’ />

第4题：

A web application contains a tag file called beta.tag in /WEB-INF/tags/alpha. A JSP page called sort.jspexists in the web application and contains only this JSP code： 1.<%@ taglib prefix="x" 2.tagdir="/WEB-INF/tags/alpha" %> 3. The sort.jsp page is requested. Which two are true？（）

• A、Tag files can only be accessed using a tagdir attribute.
• B、The sort.jsp page translates successfully and invokes the tag defined by beta.tag.
• C、The sort.jsp page produces a translation error because a taglib directive must always have a uriattribute.
• D、Tag files can only be placed in /WEB-INF/tags， and NOT in any subdirectories of /WEB- INF/tags.
• E、The tagdir attribute in line 2 can be replaced by a uri attribute if a TLD referring to beta.tag is createdand added to the web application.

第5题：

All of your JSPs need to have a link that permits users to email the web master. This web application islicensed to many small businesses， each of which have a different email address for the web master. Youhave decided to use a context parameter that you specify in the deployment descriptor， like this： 42. 43.webmasterEmail 44.master@example.com 45. Which JSP code snippet creates this email link？（）

• A、At deploy time， Java EE containers add a directory called META-INF directly into the MyApp directory.
• B、At deploy time， Java EE containers add a file called MANIFEST.MF directly into the MyApp directory.
• C、It can instruct your Java EE container to verify， at deploy time， whether you have properly configured your application’s classes.

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. 11.  14. 15. Which JSP code snippet declares that this JSP Document is a JavaScript file？（）

• B、<jsp:page contentType='application/javascript' />
• C、<jsp:document contentType='application/javascript' />
