This information must NOT be accessible to any other servlet, JSP or session in the webapp. Which two techniques can you use to accomplish this goal? (Choose two.)
- A. Add parameters to the JSP's URL when generating the request dispatcher.
- B. Add parameters to the request object.
- C. Add attributes to the session object.
- D. Add attributes on the request object.
- E. Use the pageContext object to add request attributes.

- B. pageContext.getRequest().setAttribute("name", theValue);
- C. pageContext.getSession().setAttribute("name", theValue);

- E. pageContext.setAttribute("name", getSession());

Correct Answer: C,F 🗳️
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:insert page='/WEB-INF/jsp/header.jsp'>
<jsp:param name='pageTitle' value='Welcome Page' />
</jsp:insert> - B. <jsp:include page='/WEB-INF/jsp/header.jsp'> <jsp:param name='pageTitle' value='Welcome Page' /> </jsp:include>
- C. <jsp:include page='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:include> - D. <jsp:insert page='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:insert> - E. <jsp:include file='/WEB-INF/jsp/header.jsp'>
${pageTitle='Welcome Page'}
</jsp:include>
Correct Answer: B 🗳️
Which element of the web application deployment descriptor defines the servlet class associated with a servlet instance?
- A. <servlet-mapping>

- F. <class>
Correct Answer: B 🗳️
