第2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=’${bodyURL}’ />
• D、<jsp：include file=’${bodyURL}’ />
• E、<jsp：insert page=’<%= bodyURL %>’ />

第3题：

Your web application uses a simple architecture in which servlets handle requests and then forward to aJSP using a request dispatcher. You need to pass information calculated by the servlet to the JSP；furthermore， that JSP uses a custom tag and must also process this information. This information mustNOT be accessible to any other servlet， JSP or session in the webapp. How can you accomplish this goal？（）

• A、Store the data in a public instance variable in the servlet.
• B、Add an attribute to the request object before using the request dispatcher.
• C、Add an attribute to the context object before using the request dispatcher.
• D、This CANNOT be done as the tag handler has no means to extract this data.

第7题：

You are building your own layout mechanism by including dynamic content for the page’s header and footersections. The footer is always static， but the header generates the

第9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.
