Q: 96 Assume a JavaBean com.example.GradedTestBean exists and has two attributes. The attribute name is of type java.lang.String and the attribute score is of type java.lang.Integer.
An array of com.example.GradedTestBean objects is exposed to the page in a request-scoped attribute called results. Additionally, an empty java.util.HashMap called resultMap is placed in the page scope.

Q: 97 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>

Q: 98 A web application contains a tag file called beta.tag in /WEB-INF/tags/alpha. A JSP page called sort.jsp exists in the web application and contains only this JSP code:
1. <%@ taglib prefix="x"
2. tagdir="/WEB-INF/tags/alpha" %>
3. <x:beta />
The sort.jsp page is requested.
Which two are true? (Choose two.)
B. The sort.jsp page translates successfully and invokes the tag defined by beta.tag.
C. The sort.jsp page produces a translation error because a taglib directive must always have a uri attribute.
D. Tag files can only be placed in /WEB-INF/tags, and NOT in any subdirectories of /WEB-INF/tags.
E. The tagdir attribute in line 2 can be replaced by a uri attribute if a TLD referring to beta.tag is created and added to the web application.
F. The sort.jsp page produces a translation error because the tagdir attribute on lines 1-2 specifies a directory other than /WEB-INF/tags, which is illegal.

Q: 104 Users of your web application have requested that they should be able to set the duration of their sessions. So for example, one user might want a webapp to stay connected for an hour rather than the webapp's default of fifteen minutes; another user might want to stay connected for a whole day.
