• Question 153:

  Servlet A receives a request that it forwards to servlet B within another web application in the same web container. Servlet A needs to share data with servlet B and that data must not be visible to other servlets in A's web application. In which object can the data that A shares with B be stored?

• Question 154:

  You have built a web application that you license to small businesses. The webapp uses a context parameter, called licenseExtension, which enables certain advanced features based on your client's license package. When a client pays for a specific service, you provide them with a license extension key that they insert into the of the deployment descriptor. Not every client will have this context parameter so you need to create a context listener to set up a default value in the licenseExtension parameter. Which code snippet will accomplish this goal?

  A. You cannot do this because context parameters CANNOT be altered programmatically.
  B. String ext = context.getParameter('licenseExtension');if ( ext == null ) {context.setParameter ('licenseExtension', DEFAULT);}
  C. String ext = context.getAttribute('licenseExtension');if ( ext == null ) {context.setAttribute ('licenseExtension', DEFAULT);}
  D. String ext = context.getInitParameter('licenseExtension');if ( ext == null ) {context.resetInitParameter ('licenseExtension', DEFAULT);}
  E. String ext = context.getInitParameter('licenseExtension');if ( ext == null ) {context.setInitParameter ('licenseExtension', DEFAULT);}
  A. You cannot do this because context parameters CANNOT be altered programmatically.

• Question 155:

  You need to store a floating point number, called Tsquare, in the session scope. Which two code snippets allow you to retrieve this value? (Choose two.)

  A. float Tsquare = session.getFloatAttribute("Tsquare");
  B. float Tsquare = (Float) session.getAttribute("Tsquare");
  C. float Tsquare = (float) session.getNumericAttribute("Tsquare");
  D. float Tsquare = ((Float) session.getAttribute.("Tsquare")).floatValue();
  E. float Tsquare = ((Float) session.getFloatAttribute.("Tsquare")).floatValue;
  F. float Tsquare = ((Float) session.getNumericAttribute.("Tsquare")).floatValue;
  B. float Tsquare = (Float) session.getAttribute("Tsquare");
  D. float Tsquare = ((Float) session.getAttribute.("Tsquare")).floatValue();

• Question 156:

• Question 158:

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

  How can this goal be accomplished?

  A. The object of the manager attribute should implement the HttpSessionBindingListener and it should call the removeAttribute method on the appropriate session attributes.
  B. The object of the manager attribute should implement the HttpSessionListener and it should call the removeAttribute method on the appropriate session attributes.
  C. The object of the manager attribute should implement the HttpSessionBindingListener and it should call the deleteAttribute method on the appropriate session attributes.
  D. The object of the manager attribute should implement the HttpSessionListener and it should call the deleteAttribute method on the appropriate session attributes.
  A. The object of the manager attribute should implement the HttpSessionBindingListener and it should call the removeAttribute method on the appropriate session attributes.
