Oracle 1Z0-858 Exam Syllabus Topics:

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

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) request.setAttribute("orderID", orderID);
request.setAttribute("jspURL", jspURL);
RequestDispatcher view
= context.getRequestDispatcher("/WEB-INF/retreiveOrder.do");
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) 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);

2. Given a web application in which the cookie userName is expected to contain the name of the user. Which EL expression evaluates to that user name?

B) ${cookie.userName}
C) ${cookies.get('userName')}

C) A <security-constraint> tag can have many <web-resource-collection> tags.
D) It is possible to construct a valid <security-constraint> tag such that, for a given resource, no user roles can access that resource.

A) The servlet's init method sets the ServletResponse's content length to 0.
B) The servlet's init method throws a ServletException.
