SUN Sun Certified Web Component Developer for J2EE 5 : 310-083

You have built a web application with tight security. Several directories of your webapp are used for internal purposes and you have overridden the default servlet to send an HTTP
403 status code for any request that maps to one of these directories. During testing, the
Quality Assurance director decided that they did NOT like seeing the bare response page generated by Firefox and Internet Explorer. The director recommended that the webapp should return a more user-friendly web page that has the same look-and-feel as the webapp plus links to the webapp's search engine. You have created this JSP page in the
/WEB-INF/jsps/error403.jsp file. You do NOT want to alter the complex logic of the default servlet. How can you declare that the web container must send this JSP page whenever a
4 03 status is generated?

• A. <error-page>
  < status-code>403</status-code>
  < url>/WEB-INF/jsps/error403.jsp</url>
  < /error-page>
• B. <error-page>
  < error-code>403</error-code>
  < location>/WEB-INF/jsps/error403.jsp</location>
  < /error-page>
• C. <error-page>
  < error-code>403</error-code>
  < url>/WEB-INF/jsps/error403.jsp</url>
  < /error-page>
• D. <error-page>
  < status-code>403</status-code>
  < location>/WEB-INF/jsps/error403.jsp</location>
  < /error-page>

Your management has required that all JSPs be created to generate XHTML-compliant content and to facilitate that decision, you are required to create all JSPs using the JSP
Document format. In the reviewOrder.jspx page, you need to use several core JSTL tags to process the collection of order items in the customer's shopping cart. Which JSP code snippets must you use in the reviewOrder.jspx page?

• A. <html xmlns:jsp="http://java.sun.com/JSP/Page"
  version="2.0"
  xmlns:c="http://java.sun.com/jsp/jstl/core">
  < !-- page content -->
  < /html>
• B. <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
  version="2.0">
  < jsp:directive.taglib prefix="c"
  uri="http://java.sun.com/jsp/jstl/core" />
  < !-- page content -->
  < /jsp:root>
• C. <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
  version="2.0"
  xmlns:c="http://java.sun.com/jsp/jstl/core">
  < !-- page content -->
  < /jsp:root>
• D. <html xmlns:jsp="http://java.sun.com/JSP/Page"
  version="2.0">
  < jsp:directive.taglib prefix="c"
  uri="http://java.sun.com/jsp/jstl/core" />
  < !-- page content -->
  < /html>

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

You want to create a filter for your web application and your filter will implement javax.servlet.Filter.
Which two statements are true? (Choose two.)

• A. The method that your filter invokes on the object it received that implements javax.servlet.FilterChain can invoke either another filter or a servlet.
• B. When your filter chains to the next filter, it should pass the same arguments it received in its doFilter method.
• C. Your filter class must also implement javax.servlet.FilterChain.
• D. Your filter class must implement an init method and a destroy method.
• E. Your filter class must implement a doFilter method that takes, among other things, an
  HTTPServletRequest object and an HTTPServletResponse object.

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