UPDATE

Here are the Jsp files, after some debugging both pages display, just when I add in the jsp:getproperty then I get the StackOverflowError.

How can i get the JSP to use these values but not cause this Overflow error?

index.jsp

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<html:html locale="true">
<head>
<title>Electronic Store | Admin</title>
<link href="qc310.css" rel="stylesheet" type="text/css">
</head>
<body>
<table border='0' cellspacing='0' cellpadding='0' width='600'>
<tr>
    <td colspan='2' bgcolor='#CCCCCC' align='center'><b>Electronic Store</b></td>
</tr>
</table>
  <br /><html:link page='/viewprod.do'>View product list</html:link> 
  <br /><html:link page='/update.do'>Update product</html:link>
 <br />
 <br />
 <table width="600" border="0">
      <tr>
        <th scope="row">______________________________________________________</th>
      </tr>
</table>
 <table border='0' cellspacing='0' cellpadding='0' width='600'>
<tr>
    <td colspan='2' align='center'><div align="left"><span class="copyright">&copy; 2006 Lukas Winn</span><br />

</tr>
</table>
