Squeaky Beans Inc. hired an outside consultant to develop their web application. To finish the job quickly, the consultant created several dozen JSP pages that directly communicate with the database. The Squeaky business team has since purchased a set of business objects to model their system, and the Squeaky developer charged with maintaining the web application must now refactor all the JSPs to work with the new system. Which pattern can the developer use to solve this problem?

• A. Service Locator
• B. Business Delegate
• C. Intercepting Filter
• D. Transfer Object

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 <context-param> 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.getAttribute('licenseExtension');
  if ( ext == null ) {
  context.setAttribute('licenseExtension', DEFAULT);
  }
• C. String ext = context.getInitParameter('licenseExtension');
  if ( ext == null ) {
  context.resetInitParameter('licenseExtension', DEFAULT);
  }
• D. String ext = context.getInitParameter('licenseExtension');
  if ( ext == null ) {
  context.setInitParameter('licenseExtension', DEFAULT);
  }
• E. String ext = context.getParameter('licenseExtension');
  if ( ext == null ) {
  context.setParameter('licenseExtension', DEFAULT);
  }
