Your web application views all have the same header， which includes the <title> tag in the <head> 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， the title of each page is unique， so you havedecided to use a variable called pageTitle to parameterize this in the header JSP， like this：
10.<title>${param.pageTitle}<title>
Which JSP code snippet should you use in your main view JSPs to insert the header and pass thepageTitle variable？（）
A.<jsp：insert page=’/WEB-INF/jsp/header.jsp’>. ${pageTitle=’Welcome Page’}. </jsp：insert>
B.<jsp：include page=’/WEB-INF/jsp/header.jsp’>. ${pageTitle=’Welcome Page’}. </jsp：include>
C.<jsp：include file=’/WEB-INF/jsp/header.jsp’>. ${pageTitle=’Welcome Page’}. </jsp：include>
D.<jsp：insert page=’/WEB-INF/jsp/header.jsp’>. <jsp：param name=’pageTitle’ value=’Welcome Page’ /> . </jsp：insert>
E.<jsp：include page=’/WEB-INF/jsp/header.jsp’>. <jsp：param name=’pageTitle’ value=’Welcome Page’ /> . </jsp：include>

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.
Given the web application deployment descriptor elements：
11.<filter>
12.<filter-name>ParamAdder</filter-name>
13.<filter-class>com.example.ParamAdder</filter-class>
14.</filter>...
24.<filter-mapping>
25.<filter-name>ParamAdder</filter-name>
26.<servlet-name>MyServlet</servlet-name>
27.<!-- insert element here -->
28.</filter-mapping>
Which element， inserted at line 27，causes the ParamAdder filter to be applied when MyServlet is invokedby another servlet using the RequestDispatcher.include method？（）
A.<include/>
B.<dispatcher>INCLUDE</dispatcher>
C.<dispatcher>include</dispatcher>
D.<filter-condition>INCLUDE</filter-condition>
E.<filter-condition>include</filter-condition>
You have a use case in your web application that adds several session-scoped attributes. At the end of theuse case， one of these objects， the manager attribute， is removed and then it needs to decide which of theother session-scoped attributes to remove.
How can this goal be accomplished？（）
A.The object of the manager attribute should implement the HttpSessionBindingListener and it should call the removeAttribute method on the appropriate session attributes.
B.The object of the manager attribute should implement the HttpSessionListener and it should call the removeAttribute method on the appropriate session attributes.
C.The object of the manager attribute should implement the HttpSessionBindingListener and it should call the deleteAttribute method on the appropriate session attributes.
D.The object of the manager attribute should implement the HttpSessionListener and it should call the deleteAttribute method on the appropriate session attributes.

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？（）
