You are creating a content management system (CMS) with a web application front-end.
The JSP that displays 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 reference section at the end of the generated web page.
The document tag handler follows the Classic tag model and the citation tag handler follows the Simple tag model. Furthermore, the citation tag could also be embedded in other custom tags that could have either the Classic or Simple tag handler model.
Which tag handler method allows the citation tag to access the document tag?

• A. public void doStartTag() {
  Tag docTag = findAncestor(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 doTag() {
  JspTag docTag = findAncestorWithClass(this, DocumentTag.class);
  ((DocumentTag)docTag).addCitation(this.docID);
  }

You need to store a Java long primitive attribute, called customerOID, into the session scope. Which two code snippets allow you to insert this value into the session? (Choose two.)

• A. long customerOID = 47L;
  session.setLongAttribute("customerOID", customerOID);
• B. long customerOID = 47L;
  session.setAttribute("customerOID", customerOID);
• C. long customerOID = 47L;
  session.setAttribute("customerOID", new Long(customerOID));
• D. long customerOID = 47L;
  session.setLongAttribute("customerOID", new Long(customerOID));
• E. long customerOID = 47L;
  session.setNumericAttribute("customerOID", customerOID);
• F. long customerOID = 47L;
  session.setNumericAttribute("customerOID", new Long(customerOID));

Which two prevent a servlet from handling requests? (Choose two.)

• A. The servlet's init method sets the ServletResponse's content length to 0.
• B. The servlet's init method does NOT return within a time period defined by the servlet container.
• C. The servlet's init method returns a non-zero status.
• D. The servlet's init method throws a ServletException.
• E. The servlet's init method sets the ServletResponse's content type to null.

Given the JSP code:
< % request.setAttribute("foo", "bar"); %>
and the Classic tag handler code:
5 . public int doStartTag() throws JspException {
6 . // insert code here
7 . // return int
8 . }
Assume there are no other "foo" attributes in the web application.
Which invocation on the pageContext object, inserted at line 6, assigns "bar" to the variable x?

• A. String x = (String) pageContext.getAttribute("foo");
• B. String x = (String)
  pageContext.getRequest().getAttribute("foo");
• C. String x = (String) pageContext.getRequestScope("foo");
• D. String x = (String) pageContext.getAttribute("foo",
  PageContext.ANY_SCOPE);
• E. It is NOT possible to access the pageContext object from within doStartTag.

To take advantage of the capabilities of modern browsers that use web standards, such as
XHTML and CSS, 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 several web forms to create screen-specific validation functions and are included in these pages with the following statement:
1 0. <head>
1 1. <script src='/scripts/screenFunctions.jsp'
1 2. language='javascript'
1 3. type='application/javascript'> </script>
1 4. </head>
1 5. <!-- body of the web form -->
Which JSP code snippet declares that this JSP Document is a JavaScript file?

• A. 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.
• B. <%@ page contentType='application/javascript' %>
• C. <jsp:page contentType='application/javascript' />
• D. <jsp:document contentType='application/javascript' />
• E. <jsp:directive.page contentType='application/javascript' />
