Question 1

Click the Exhibit button.  
Given the HTML form:

  5. Price: <input type="text" name="i2"><br> 
  6. <input type="submit">  
  7. </form>  
  8.    </body>  
  9. </html>  
Assume the product attribute does NOT yet exist in any scope.  
Which code snippet, in submit.jsp, instantiates an instance of com.example.Product that contains the results of the form submission? 
  


  1. <jsp:useBean id="com.example.Product" /> 
    <jsp:setProperty name="product" property="*" />
  2. <jsp:useBean id="product" class="com.example.Product" /> 
    ${product.name = param.i1} 
    ${product.price = param.i2}
  3. <jsp:useBean id="product" class="com.example.Product"> 
    <jsp:setProperty name="product" property="name"
    param="i1" /> 
    <jsp:setProperty name="product" property="price"
    param="i2" /> 
    </jsp:useBean>
  4. <jsp:useBean id="product" type="com.example.Product"> 
    <jsp:setProperty name="product" property="name"
    value="<%= request.getParameter( "i1" ) %>" /> 
    <jsp:setProperty name="product" property="price"
    value="<%= request.getParameter( "i2" ) %>" /> 
    </jsp:useBean>
Correct answer: C



Question 2

You need to create a JavaBean object that is used only within the current ISP page. It must NOT be accessible to any other page including those that this page might import. 
Which JSP standard action < .in accomplish this goal?


  1. <jsp:useBean id = ‘pageBean’ type = ‘com.example.MyBean’ />
  2. <jsp:useBean id = ‘pageBean’ class = ‘com.example.MyBean’ />
  3. <jsp:makeBean id = ‘pageBean’ type = ‘com.example.MyBean’ />
  4. <jsp:makeBean id = ‘pageBean’ class = ‘com.example.MyBean’ />
  5. <jsp:useBean id = ‘pageBean’ class = ‘com.example.MyBean’ />
  6. <jsp:makeBean id = ‘pageBean’ class = ‘com.example.MyBean’ />
Correct answer: B



Question 3

Given the JavaBean class:
public class MyBean { 
private Boolean roasted = false; 
public MyBean ()  
public Boolean isRoasted () { returned roasted } 
public void setRoasted (Boolean roasted) { this.roasted = roasted; ] 
} 
Assume a controller has created an instance of this bean, called setRoasted (true), and inserted the bean into the application scope using the name “myBean”. 
A JSP contains these two tags:
<jsp: useBean id = “aBean” class = “MyBean” scope = “page” \ />
<jsp: getProprty name = “aBean” property = “roasted” \ />
Which is true?


  1. the page will include the output false
  2. the page will include the output
  3. the page will report that the property roasted does not exist
  4. the page will report that the syntax of the useBean tag is incorrect
  5. the page will report that the syntax of the getProperty tag ls incorrect
Correct answer: A

Question 4

A developer chooses to avoid using singieThreadModel but wants to ensure that data If; updated in a thread safe manner. 
Which two can support this design goal? (Choose two)


  1. Store the data in a local variable.
  2. Store the data in an instance variable.
  3. Store the data in the Httpsession object.
  4. Store the data in the sarvletContext object.
  5. Store the data in the ServletRequest object.
Correct answer: AE



Question 5

You have a use in your web application that adds several session-scoped attributes. At the end of the use case, one of these objects, the manage attribute, is removed and then it needs to decide which of the other session-scoped attributes to remove. 
How can this goal be accomplished?


  1. The object of the manager attribute should implement the HttpSessionBindingListener and it should call the removeAttribute method on the appropriate session attributes.
  2. The object of the manager attribute should implement the HttpSessionListenar and it should call the removeAttribute method on the appropriate session attributes.
  3. The object of the manager attribute should implement the HttpSessionBindingListener rind it should call the deleteAttribute method on the appropriate session attributes.
  4. The object of the manager attribute should implement the HttpsessionListener and it should call the deleteAttribute method on the appropriate session attributes.
Correct answer: A



Question 6

The Squeaky Beans Inc. shopping application was initially developed for a non-distributed environment. The company recently purchased the Acme Application Server, which supports distributed Httpsession objects. When deploying the application to the server, the doployer marks it as distributable in the web application deployment descriptor to take advantage of this feature. 
Given this scenario, which two must be true? (Choose two)


  1. The J2EE web container must support migration of objects that implement serializable.
  2. The J2EE web container must use the native JVM Serialization mechanism for distributing HttpSesaion objects.
  3. As per the specification, the J2EE web container ensures that distributed Httpsassion objects will be stored in a database.
  4. Storing references to Enterprise JavaBeans components in the HttpSession object might NOT supported by J2EE web contain.
Correct answer: AD



Question 7

Given an HttpServletRequest request and an httpServletResponse response:
41. HttpSession session = null; 
42. / / insert code here 
43. if (session = = null) { 
44.     / / do something if session does not exist 
45. } else { 
46.    / / do something if session exists 
47. } 
To implement the design intent, which statement must be inserted at line 42?


  1. session = response.getSession ();
  2. session = request.getSession ();
  3. session = request.getSession (true);
  4. session = request.getSession (false);
  5. session = request.getSession (“jsessionid”);
Correct answer: D



Question 8

Users of your web application have requested that they should be able to set the duration of their sessions. So for example, one user might want a webapp to stay connected for an hour rather than the webapp's default of fifteen minutes; another user might want to stay connected for a whole day. 
Furthermore, you have a special login servlet that performs user authentication and retrieves the object from the database. You want to augment this code to set up the user's pecified session duration. 
Which code snippet   in the login servlet will accomplish this goal?


  1. User user = / / retrieves the user objects object from the database 
    session.setDurationInterval (user.getSessionDuration());
  2. User user = / / retrieves the User objects from the database 
    session.setInactiveInterval (user.getSessionDuration());
  3. User user = / / retrieves the user objects object from the database 
    session.setInactiveInterval (user.get.SessionDuration());
  4. User user = / / retrieves the user objects object from the database 
    session.setDuration (user.getSessionDuration());
  5. User user = / / retrieves the user objects object from the database 
    session.setMaxInactiveInterval (user.getSessionDuration());
  6. User user = / / retrieves the user objects object from the database 
    session.setMaxDurationInterval (user.getSessionDuration());
Correct answer: E



Question 9

Which interface must a class implement so that instances of the class are notified after any object added to a session?


  1. javax.servlet.http.HttpSessionListener
  2. javax.servlet.http.HttpSessionValueListener
  3. javax.servlet.http.HttpSessionBindingListener
  4. javax.servlet.http.HttpSessionAttributeListener
Correct answer: D



Question 10

Which statement is true about web container session management?


  1. Access to session-scoped attributes is guaranteed to be thread-safe by the web container.
  2. To activate URL rewriting, the developer must use the HttpServletResponse.setURLRewriting method.
  3. If the web application uses HTTPS, then the web container may use the data on the HTTPS request stream to identify the client.
  4. The JSESSIONID cookie is stored permanently on the client so that a user may return to the web application and the web container will rejoin that session.
