A web application uses the HttpSession mechanism to determine if a user is "logged in." When a usersupplies a valid user name and password, an HttpSession is created for that user. The user has access tothe application for only 15 minutes after logging in. The code must determine how long the user has beenlogged in, and if this time is greater than 15 minutes, must destroy the HttpSession.
Which method in HttpSession is used to accomplish this?()
A.Getcreationtime
B.Invalidateafter
C.Getlastaccessedtime
D.Getmaxinactiveinterval
Given an HttpServletRequest request and an HttpServletResponse response:
41.HttpSession session = null;
42.// insert code here
43.if(session == null) {
44.// do something if session does not exist
45.} else {
46.// do something if session exists47. }
To implement the design intent,which statement must be inserted at line 42?()
A.session = response.getSession();
B.session = request.getSession();
C.session = request.getSession(true);
D.session = request.getSession(false);
E.session = request.getSession("jsessionid");
A.It can be invoked only from the doGet or doPost methods.
B.It can be used independently of the getRemoteUser method.
C.Can return "true" even when its argument is NOT defined as a valid role name in the deployment descriptor.
D.Using the isUserInRole method overrides any declarative authentication related to the method in which it is invoked.
A.<realm-name>
B.<url-pattern>
C.<description>
D.<web-resource-name>

A.The session object must be declared explicitly.
B.The request and response objects are available implicitly.
C.The output stream is available through the implicit outStream object.
D.The servlet context is available through the implicit servletContext object.
E.The JspContext for the tag file is available through the implicit jspContext object.
You are creating a content management system (CMS) with a web application front-end. The JSP thatdisplays a given document in the CMS has the following general structure:
1. <%-- tag declaration --%>
2. <t:document>
...
11. <t:paragraph>... <t:citation docID=’xyz’ /> ...</t:paragraph> ...
99. </t:document>
The citation tag must store information in the document tag for the document tag to generate a referencesection at the end of the generated web page. The document tag handler follows the Classic tag model andthe citation tag handler follows the Simple tag model. Furthermore, the citation tag could also be embeddedin other custom tags that could have either the Classic or Simple tag handler model.
Which tag handlermethod allows the citation tag to access the document tag?()
A.public void doTag() {JspTag docTag = findAncestorWithClass(this, DocumentTag.class); ((DocumentTag)docTag).addCitation(this.docID);}
B.public void doStartTag() {JspTag docTag = findAncestorWithClass(this, DocumentTag.class); ((DocumentTag)docTag).addCitation(this.docID);}
C.public void doTag() {. Tag docTag = findAncestor(this, DocumentTag.class); . ((DocumentTag)docTag).addCitation(this.docID);. }
D.public void doStartTag() {. Tag docTag = findAncestor(this, DocumentTag.class); . ((DocumentTag)docTag).addCitation(this.docID);. }
Given:
3.public class MyTagHandler extends TagSupport {
4.public int doStartTag() {
5.// insert code here
6.// return an int
7.}
8.// more code here
...
18.}
There is a single attribute foo in the session scope.
Which three code fragments,inserted independently atline 5,return the value of the attribute?()

B.Object o = pageContext.findAttribute("foo");
C.Object o = pageContext.getAttribute("foo",PageContext.SESSION_SCOPE);
D.HttpSession s = pageContext.getSession();Object o = s.getAttribute("foo");
