Table populated by scriptlet code not displaying

Question

I have a table in a web page that is populated by scriptlet code. I've only been introduced to this code base for about a month, and new to working in JSPs, MVC framework, etc. This web application was also written in the early 2000s, so as one would expect, many things are broken. One thing that puzzles me is this table:

  <table border="0" cellpadding="2" cellspacing="0" width="480">

<%
    for ( int i=0; i< fds.size(); i++)
    {
        FreqDeptInfo                fdi     =   (FreqDeptInfo)fds.elementAt(i);

%>
        <tr class="<%=(i%2 == 0)? "row": "row1"%>"  id="<%=i%>" onclick="userclickhandler(this, <%=i%>)" ONDBLCLICK="parent.editTollFreeCodeHandler(form1)" onkeydown="upDown(event, form1)">
            <td width="175" align="left" class="smalltext"><%=ApplicationBean.escapeHTML(ApplicationBean.getDetailedName(fdi.sDeptName))%></td>
            <td width="130" align="left" class="smalltext"><%=ApplicationBean.escapeHTML(ApplicationBean.getEntitySite(fdi.sDeptName))%></td>
            <td width="80" align="left" class="smalltext"><%=ApplicationBean.escapeHTML(ApplicationBean.getFormattedDeptFrequency(fdi.dProbability))%></td>
        </tr>
<%
    }
%>

  </table>

To be honest, I haven't any idea what the scriptlet code is doing, all I know is that this for loop is populating the table. Without knowing exactly what the servlet is doing, is there any obvious reason why the table remains unpopulated when inspected in the browser?
