Q56. As a convenience feature, your web pages include an Ajax request every five minutes to a special servlet that monitors the age of the user’s session. The client-side JavaScript that handles the Ajax callback displays a message on the screen as the session ages. The Ajax call does NOT pass any cookies, but it passes the session ID in a request parameter called sessionID. In addition, assume that your webapp keeps a hasmap of session objects by the ID. Here is a partial implementation of this servlet:

Q59. 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: objoctID. 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.split(",")}' 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}' delims=',' var='item'> 

<li>${item}</li> 

</c:forTokens> 

</ul>
