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

You are building a Front Controller using a JSP page and you need to determine if the user's session has NOT been created yet and perform some special processing for this case. Which scriptlet code snippet will perform this test?

• A.<% if ( request.getSession(false) == null ) {
  // special processing
  } %>
• B.<% if ( requestObject.getSession(false) == null ) {
  // special processing
  } %>
• C.<% if ( requestObject.getHttpSession(false) == null ) {
  // special processing
  } %>
• D.<% if ( request.getHttpSession(false) == null ) {
  // special processing
  } %>

Which is true about the web container request processing model?

• A.Filters associated with a named servlet are applied in the order they appear in the web application deployment descriptor file.
• B.A filter defined for a servlet must always forward control to the next resource in the filter chain.
• C.The init method on a filter is called the first time a servlet mapped to that filter is invoked.
• D.If the init method on a filter throws an UnavailableException, then the container will make no further attempt to execute it.
