    1.15 +<p> As you can see there are different tags of the cewolf taglib
    1.16 +involved. The first &lt;cewolf:chart&gt; tag defines a chart with all
    1.17 +its parameters. The concrete rendering is handled by the
    1.18 +&lt;cewolf:img&gt; tag which adds the correct &lt;img&gt; tag in the
    1.19 +rendered HTML page. The connection between both cewolf tags inside the
    1.20 +JSP is specified by using the same <tt>id</tt> attributes. </p>
    1.21 +<p> When calling this JSP from a client browser you should see the page
    1.22 +view statistic chart. If you got a broken image have a look at your
    1.23 +container's log files. </p>
