Question 3

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

Question 4

An appropriate jsp:useBean tag has been placed into a JSP, and identified the bean using the name "theBean".
The bean class includes a method with the following signature:
public boolean isOurCustomer ()
You wish to insert the test true or false into the output HTML based on the return value of this method. Which is true?

A. This can be achieved using a tag of the form: <jsp:getProperty id= "theBean" invoke
"getOurCustomer" /> B. This cannot be achieved because the method isOurCustomer () does not adhere to JavaBeans conventions. C. This can be achieved using a tag of the form: <jsp:getProperty id= "theBean" property= "ourCustomer"
/> D. This cannot be achieved because the return type of isOurCustomer () is not String E. This can be achieved using a tag of the form: <jsp:getProperty name= "theBean" type= "boolean" property= "ourCustomer" /> F. This can be achieved using a tag of the form: <jsp:getProperty name= "theBean" property
"ourCustomer" />
