Which JSP standard action can be used to import content from a resource called foo.jsp?

• A. <jsp:include>foo.jsp</jsp:include>
• B. <jsp:import>foo.jsp</jsp:import>

Assume that a news tag library contains the tags lookup and item:
lookup Retrieves the latest news headlines and executes the tag body once for each headline. Exposes a NESTED page-scoped attribute called headline of type com.example.Headline containing details for that headline.
item Outputs the HTML for a single news headline. Accepts an attribute info of type com.example.Headline containing details for the headline to be rendered.Which snippet of JSP code returns the latest news headlines in an HTML table, one per row?

• A. <table>
  < news:lookup>
  < tr>
  < td><news:item info="${headline}" /></td>
  < /tr>
  < /news:lookup>
  < /table>
• B. <table>
  < tr>
  < td>
  < news:lookup />
  < news:item info="${headline}" />
  < /td>
  < /tr>
  < /table>
• C. <table>
  < tr>
  < news:lookup>
  < td><news:item info="${headline}" /></td>
  < /news:lookup>
  < /tr>
  < /table>
• D. <news:lookup />
  < table>
  < tr>
  < td><news:item info="${headline}" /></td>
  < /tr>
  < /table>

You are building a dating web site. The client's date of birth is collected along with lots of other information. You have created an EL function with the signature:
calcAge(java.util.Date):int and it is assigned to the name, age, in the namespace, funct. In one of your JSPs you need to print a special message to clients who are younger than 25.
Which EL code snippet will return true for this condition?

• A. ${calcAge(client.birthDate) < 25}
• B. ${funct:age(client.birthDate) < 25}
• C. ${funct:calcAge[client.birthDate] < 25}
• D. ${funct:calcAge(client.birthDate) < 25}
• E. ${calcAge[client.birthDate] < 25}
• F. ${funct:age[client.birthDate] < 25}

Your web site has many user-customizable features, for example font and color preferences on web pages. Your IT department has already built a subsystem for user preferences using the Java SE platform's lang.util.prefs package APIs, and you have been ordered to reuse this subsystem in your web application. You need to create an event listener that constructs the preferences factory and stores it in the application scope for later use. Furthermore, this factory requires that the URL to a database must be declared in the deployment descriptor like this:
4 2. <context-param>
4 3. <param-name>prefsDbURL</param-name>
4 4. <param-value>
4 5. jdbc:pointbase:server://dbhost:4747/prefsDB
4 6. </param-value>
4 7. </context-param>
Which partial listener class will accomplish this goal?

• A. public class PrefsFactoryInitializer implements ContextListener {
  public void contextCreated(ServletContext ctx) {
  String prefsURL = ctx.getParameter("prefsDbURL");
  PreferencesFactory myFactory = makeFactory(prefsURL);
  ctx.putAttribute("myPrefsFactory", myFactory);
  }
  // more code here
  }
• B. public class PrefsFactoryInitializer implements ServletContextListener { public void contextInitialized(ServletContextEvent e) {
  ServletContext ctx = e.getServletContext();
  String prefsURL = ctx.getInitParameter("prefsDbURL");
  PreferencesFactory myFactory = makeFactory(prefsURL);
  ctx.setAttribute("myPrefsFactory", myFactory);
  }
  // more code here
  }
• C. public class PrefsFactoryInitializer implements ServletContextListener { public void contextCreated(ServletContext ctx) {
  String prefsURL = ctx.getInitParameter("prefsDbURL");
  PreferencesFactory myFactory = makeFactory(prefsURL);
  ctx.setAttribute("myPrefsFactory", myFactory);
  }
  // more code here
  }
• D. public class PrefsFactoryInitializer implements ContextListener {
  public void contextInitialized(ServletContextEvent e) {
  ServletContext ctx = e.getContext();
  String prefsURL = ctx.getParameter("prefsDbURL");
  PreferencesFactory myFactory = makeFactory(prefsURL);
  ctx.putAttribute("myPrefsFactory", myFactory);
  }
  // more code here
  }

Which JSTL code snippet produces the output "big number" when X is greater than 42, but outputs "small number" in all other cases?

• A. <c:choose test='<%= (X > 42) %>'>
  < c:then>big number</c:when>
  < c:else>small number</c:otherwise>
  < /c:choose>
• B. <c:if>
  < c:then test='<%= (X > 42) %>'>big number</c:then>
  < c:else>small number</c:else>
  < /c:if>
• C. <c:if test='<%= (X > 42) %>'>
  < c:then>big number</c:then>
  < c:else>small number</c:else>
  < /c:if>
• D. <c:choose>
  < c:when test='<%= (X > 42) %>'>big number</c:when>
  < c:otherwise>small number</c:otherwise>
  < /c:choose>
• E. <c:choose test='<%= (X > 42) %>'>
  < c:when>big number</c:when>
  < c:otherwise>small number</c:otherwise>
  < /c:choose>
