And this request from a browser:
http://www.sun.com/SCWCDtestApp/register

Your web application views all have the same header, which includes the <title> tag in the <head> element of the rendered HTML. You have decided to remove this redundant HTML code from your JSPs and put it into a single JSP called /WEB-INF/jsp/header.jsp. However, the title of each page is unique, so you have decided 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 the pageTitle variable?

• A. <jsp:include page='/WEB-INF/jsp/header.jsp'>
  ${pageTitle='Welcome Page'}
  </jsp:include>
• B. <jsp:insert page='/WEB-INF/jsp/header.jsp'>
  <jsp:param name='pageTitle' value='Welcome Page' />
  </jsp:insert>
• C. <jsp:include page='/WEB-INF/jsp/header.jsp'>
  <jsp:param name='pageTitle' value='Welcome Page' />
  </jsp:include>
• D. <jsp:include file='/WEB-INF/jsp/header.jsp'>
  ${pageTitle='Welcome Page'}
  </jsp:include>
• E. <jsp:insert page='/WEB-INF/jsp/header.jsp'>
  ${pageTitle='Welcome Page'}
  </jsp:insert>

Which two about WAR files are true? (Choose two.)

• A. WAR files must be located in the web application library directory.
• B. WAR files must be created by using archive tools designed specifically for that purpose.
• C. The web container must allow access to resources in JARs in the web application library directory.
• D. WAR files must contain the web application deployment descriptor.
• E. The web container must serve the content of any META-INF directory located in a WAR file.

Assume a JavaBean com.example.GradedTestBean exists and has two attributes. The attribute name is of type java.lang.String and the attribute score is of type java.lang.Integer.
An array of com.example.GradedTestBean objects is exposed to the page in a requestscoped attribute called results. Additionally, an empty java.util.HashMap called resultMap is placed in the page scope.
A JSP page needs to add the first entry in results to resultMap, storing the name attribute of the bean as the key and the score attribute of the bean as the value.
Which code snippet of JSTL code satisfies this requirement?

• A. <c:set target="${resultMap}" property="${results[0].name}"
  value="${results[0].score}" />
• B. <c:set var="${resultMap}" key="${results[0].name}"
  value="${results[0].score}" />
• C. <c:set var="resultMap" property="${results[0].name}"
  value="${results[0].score}" />
• D. ${resultMap[results[0].name] = results[0].score}
• E. <c:set var="resultMap" property="${results[0].name}">
  ${results[0].value}
  </c:set>
