<web-resource-name>Foo</web-resource-name>
104.
<url-pattern>/Bar/Baz/*</url-pattern>
105.
<http-method>POST</http-method>

<auth-constraint>
108.
<role-name>DEVELOPER</role-name>

In a JSP-centric shopping cart application, you need to move a client's home address of the Customer object into the shipping address of the Order object. The address data is stored in a value object class called Address with properties for: street address, city, province, country, and postal code. Which two JSP code snippets can be used to accomplish this goal? (Choose two.)

• A.  <c:setProperty name='${order}' property='shipAddress'> <jsp:getProperty name='client' property='homeAddress' /> </c:setProperty>
• B.  <jsp:setProperty name='${order}' property='shipAddress' value='${client.homeAddress}' />
• C.  <c:set var='order' property='shipAddress' value='${client.homeAddress}' />
• D.  <c:set var='order' property='shipAddress'> <jsp:getProperty name='client' property='homeAddress' /> </c:store>
• E.  <c:set target='${order}' property='shipAddress' value='${client.homeAddress}' />
• F.  <c:set target='${order}' property='shipAddress'> <jsp:getProperty name='client' property='homeAddress' /> </c:set>

You have created a JSP that includes instance variables and a great deal of scriptlet code. Unfortunately, after extensive load testing, you have discovered several race conditions in your JSP scriptlet code. To fix these problems would require significant recoding, but you are already behind schedule. Which JSP code snippet can you use to resolve these concurrency problems?

• A.  <%@ page isThreadSafe='false' %>
• B.  <%@ page useSingleThreadModel='true' %>
• C.  <%@ implements SingleThreadModel %>
• D.  <%@ page implements='SingleThreadModel' %>
• E.  <%! implements SingleThreadModel %>

Your IT department is building a lightweight Front Controller servlet that invokes an application logic object with the interface:
public interface ApplicationController {
public String invoke(HttpServletRequest request)
}
The return value of this method indicates a symbolic name of the next view. From this name, the Front Controller servlet looks up the JSP URL in a configuration table. This URL might be an absolute path or a path relative to the current request. Next, the Front Controller servlet must send the request to this JSP to generate the view. Assume that the servlet variable request is assigned the current HttpServletRequest object and the variable context is assigned the webapp's ServletContext.
Which code snippet of the Front Controller servlet accomplishes this goal?

• A.  Dispatcher view = context.getDispatcher(viewURL); view.forwardRequest(request, response);
• B.  Dispatcher view = request.getDispatcher(viewURL); view.forwardRequest(request, response);
• C.  RequestDispatcher view = request.getRequestDispatcher(viewURL);
  view.forward(request, response);
• D.  RequestDispatcher view = context.getRequestDispatcher(viewURL); view.forward(request, response);
