SUN Sun Certified Web Component Developer for J2EE 5 Sample Questions:
1. 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.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>
2. Given the JSP code:
