You are creating a JSP page to display a collection of data. This data can be displayed in several different ways so the architect on your project decided to create a generic servlet that generates a comma-delimited string so that various pages can render the data in different ways. This servlet takes on request parameter: objectID. Assume that this servlet is mapped to the URL pattern: /WEB-INF/data.
In the JSP you are creating, you need to split this string into its elements separated by commas and generate an HTML <ul> list from the data.
Which JSTL code snippet will accomplish this goal?

• A. <c:import var='dataString' url='/WEB-INF/data'>
  <c:param name='objectID' value='${currentOID}' />
  </c:import>
  <ul>
  <c:forTokens items'${dataString.split(",")}' var='item'>
  <li>${item}</li>
  </c:forTokens>
  </ul>
• B. <c:import varReader='dataString' url='/WEB-INF/data'>
  <c:param name='objectID' value='${currentOID}' />
  </c:import>
  <ul>
  <c:forTokens items'${dataString}' delims=',' var='item'>
  <li>${item}</li>
  </c:forTokens>
  </ul>
• C. <c:import var='dataString' url='/WEB-INF/data'>
  <c:param name='objectID' value='${currentOID}' />
  </c:import>
  <ul>
  <c:forTokens items'${dataString}' delims=',' var='item'>
  <li>${item}</li>
  </c:forTokens>
  </ul>
• D. <c:import varReader='dataString' url='/WEB-INF/data'>
  <c:param name='objectID' value='${currentOID}' />
  </c:import>
  <ul>
  <c:forTokens items'${dataString.split(",")}' var='item'>
  <li>${item}</li>
  </c:forTokens>
  </ul>

Given: http://com.example/myServlet.jsp?num=one&num=two&num=three Which two produce the output "one, two and three"? (Choose two.)

• A. ${paramValues[0],[1] and [2]}
• B. ${param.num[0],[1] and [2]}

• F. ${paramValues.num[0]}, ${paramValues.num[1]} and ${paramValues.num[2]}
• G. ${param.num[0]}, ${param.num[1]} and ${param.num[2]}

In a JSP-centric web application, you need to create a catalog browsing JSP page. The catalog is stored as a List object in the catalog attribute of the webapp's ServletContext object. Which scriptlet code snippet gives you access to the catalog object?

• A. <% List catalog = context.getAttribute("catalog"); %>
• B. <% List catalog = application.getAttribute("catalog"); %>
• C. <% List catalog = servletContext.getAttribute("catalog"); %>
• D. <% List catalog = config.getAttribute("catalog"); %>

• A. The EVAL_BODY_BUFFERED constant is a valid return value for the doStartTag method.
• B. The SKIP_PAGE constant is a valid return value for the doStartTag method.
• C. The doAfterBody method is NOT called.
• D. The EVAL_PAGE constant is a valid return value for the doEndTag method.
