Given your example below uses a scriptlet to loop through your data, why not
just chuck the use of jsp:getProperty and use the scriptlet to do the whole
job. That can't be that sacreligious. For example:
<jsp:useBean id='customers' class='com.bobfoster.Customers'>
<ol>
<% for (int row = 1; row < customers.size(); row++) { %>
<li>
<% out.println(custName.getCustName(row)); } %>
</ol>
or something along those lines.
