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？（）

• A、<%@ import file=’/common/menu.html’ %>
• B、<%@ page import=’/common/menu.html’ %>
• C、<%@ import page=’/common/menu.html’ %>
• D、<%@ include file=’/common/menu.html’ %>

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 %>’ />

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 %>
• C、<%! implements SingleThreadModel %>
• D、<%@ page useSingleThreadModel=’true’ %>
• E、<%@ page implements=’SingleThreadModel’ %>

You are creating a new JSP page and you need to execute some code that acts when the page is firstexecuted， but only once. Which three are possible mechanisms for performing this initialization code？（）

• A、In the init method.
• B、In the jspInit method.
• C、In the constructor of the JSP’s Java code.
• D、In a JSP declaration， which includes an initializer block.
• E、In a JSP declaration， which includes a static initializer block.

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？（）

• 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.
