Oracle Java Enterprise Edition 5 Web Component Developer Certified Professional Sample Questions:

Question #1
You have a simple web application that has a single Front Controller servlet that dispatches to JSPs to generate a variety of views. Several of these views require further database processing to retrieve the necessary order object using the orderID request parameter. To do this additional processing, you pass the request first to a servlet that is mapped to the URL pattern /WEB-INF/retreiveOrder.do in the deployment descriptor. This servlet takes two request parameters, the orderID and the jspURL. It handles the database calls to retrieve and build the complex order objects and then it dispatches to the jspURL.
Which code snippet in the Front Controller servlet dispatches the request to the order retrieval servlet?

A. String T="/WEB-INF/retreiveOrder.do?orderID=%d&jspURL=%s";
String url = String.format(T, orderID, jspURL);
Dispatcher view
= context.getDispatcher(url);
view.forwardRequest(request, response);
B. String T="/WEB-INF/retreiveOrder.do?orderID=%d&jspURL=%s";
String url = String.format(T, orderID, jspURL);
RequestDispatcher view
= context.getRequestDispatcher(url);
view.forward(request, response);
C. request.setParameter("orderID", orderID);
request.setParameter("jspURL", jspURL);
Dispatcher view
= request.getDispatcher("/WEB-INF/retreiveOrder.do");
view.forwardRequest(request, response);
D. request.setAttribute("orderID", orderID);
request.setAttribute("jspURL", jspURL);
RequestDispatcher view
= context.getRequestDispatcher("/WEB-INF/retreiveOrder.do");
view.forward(request, response);

Question #2
Given the definition of MyServlet:
11.
public class MyServlet extends HttpServlet {
12.
public void service(HttpServletRequest request,
13.
HttpServletResponse response)
14.
throws ServletException, IOException {
15.
HttpSession session = request.getSession(); 16 session.setAttribute("myAttribute","myAttributeValue");
17.
session.invalidate();
18.
response.getWriter().println("value=" +
19.
session.getAttribute("myAttribute"));
20.
}
21.
}
What is the result when a request is sent to MyServlet?

A. An InvalidSessionException is thrown at runtime.
B. The string "value=null" appears in the response stream.
C. An IllegalStateException is thrown at runtime.
D. The string "value=myAttributeValue" appears in the response stream.

Question #3
Which two prevent a servlet from handling requests? (Choose two.)

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

Question #4
Given: http://com.example/myServlet.jsp?num=one&num=two&num=three Which two produce the output "one, two and three"? (Choose two.)

A. ${paramValues["num"][0]}, ${paramValues["num"][1]} and ${paramValues["num"][2]}
B. ${parameterValues["num"]["0"]}, ${parameterValues["num"]["1"]} and ${parameterValues["num"]["2"]}
C. ${parameterValues.num[0]}, ${parameterValues.num[1]} and ${parameterValues.num[2]}
D. ${param.num[0]}, ${param.num[1]} and ${param.num[2]}
E. ${param.num[0],[1] and [2]}
F. ${paramValues.num[0]}, ${paramValues.num[1]} and ${paramValues.num[2]}
G. ${paramValues[0],[1] and [2]}

Question #5
A developer has created a web application that includes a servlet for each use case in the application. These servlets have become rather difficult to maintain because the request processing methods have become very large. There is also common processing code in many servlets because these use cases are very similar. Which two design patterns can be used together to refactor and simplify this web application? (Choose two.)

A. Session Facade
B. View Helper
C. Business Delegate
D. Proxy
E. Front Controller
F. Model-View-Controller
