1. Assume that a news tag library contains the tags lookup and item:
lookup Retrieves the latest news headlines and executes the tag body once for each headline. Exposes a NESTED page-scoped attribute called headline of type com.example.Headline containing details for that headline.
item Outputs the HTML for a single news headline. Accepts an attribute info of type com.example.Headline containing details for the headline to be rendered.Which snippet of JSP code returns the latest news headlines in an HTML table, one per row?

A) <table>
< news:lookup>
< tr>
< td><news:item info="${headline}" /></td>
< /tr>
< /news:lookup>
< /table>
B) <table>
< tr>
< news:lookup>
< td><news:item info="${headline}" /></td>
< /news:lookup>
< /tr>
< /table>
C) <table>
< tr>
< td>
< news:lookup />
< news:item info="${headline}" />
< /td>
< /tr>
< /table>
D) <news:lookup />
< table>
< tr>
< td><news:item info="${headline}" /></td>
< /tr>
< /table>

2. Click the Exhibit button.
Given the JSP code:
1 . <%
2 . pageContext.setAttribute( "product",
3 . new com.example.Product( "Pizza", 0.99 ) );
4 . %>
5 . <%-- insert code here --%>
Which two, inserted at line 5, output the name of the product in the response? (Choose two.)

A) <jsp:useBean id="product" class="com.example.Product" />
< %= product.getName() %>
B) <%= product.getName() %>
C) <jsp:useBean id="com.example.Product" scope="page">
< %= product.getName() %>
< /jsp:useBean>
D) <jsp:useBean id="product" type="com.example.Product">
< %= product.getName() %>
< /jsp:useBean>
E) <jsp:useBean id="product" type="com.example.Product"
scope="page" />
< %= product.getName() %>

3. You are building your own layout mechanism by including dynamic content for the page's header and footer sections. The footer is always static, but the header generates the <title> tag that requires the page name to be specified dynamically when the header is imported.
Which JSP code snippet performs the import of the header content?

A) <jsp:include page='/WEB-INF/jsp/header.jsp'>
< jsp:attribute name='pageName' value='Welcome Page' />
< /jsp:include>
B) <jsp:include page='/WEB-INF/jsp/header.jsp'>
< jsp:param name='pageName' value='Welcome Page' />
< /jsp:include>
C) <jsp:import page='/WEB-INF/jsp/header.jsp'>
< jsp:attribute name='pageName' value='Welcome Page' />
< /jsp:import>
D) <jsp:import page='/WEB-INF/jsp/header.jsp'>
< jsp:param name='pageName' value='Welcome Page' />
< /jsp:import>

4. Given the element from the web application deployment descriptor:
< jsp-property-group>
< url-pattern>/main/page1.jsp</url-pattern>
< scripting-invalid>true</scripting-invalid>
< /jsp-property-group>
and given that /main/page1.jsp contains:
< % int i = 12; %>
< b><%= i %></b>
What is the result?

A) The JSP fails to execute.
B) <b></b>
C) <b>12</b>
D) <% int i = 12 %>
< b><%= i %></b>

5. Your web application uses a simple architecture in which servlets handle requests and then forward to a JSP using a request dispatcher. You need to pass information calculated in the servlet to the JSP for view generation. 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 on the request object.
D) Add attributes to the session object.
E) Use the pageContext object to add request attributes.
