trouble accessing a data bean through JSP

[dinesh]

Hi. I'm trying to call a database access bean through a JSP. (the search
field is irrelevent, it's referencing a controlling servlet) Here's my code:
menu.jsp
--------------------------------
<%@page import="java.util.*"%>
<jsp:useBean id="DbBean" scope="application" class="showMeItNow.DbBean"/>

<%
String base = (String) application.getAttribute("base");
%>


<table width="150" cellpadding="5" height="75" cellspacing="0" border="0">
<tr>
<td>
<form>
<input type="hidden" name="action" value="search">
<input type="text" name="keyword" size="10">
<input type="submit" value="go">
</form>
</td>
</tr>
<tr>
<td>category</td>
</tr>
<tr>
<tr valign="top">

<%
Hashtable categories = DbBean.getCategories();
Enumeration.categoryIds = categories.keys();
while (categoryIds.hasMoreElements()) {
Object categoryId = categoryIds.nextElement();
out.println("<a href=" + base + "? action=browseCatalog&categoryId=" +
categoryId.toString() + ">" + categories.get(categoryId) + "</a><br>");
}

%>
</td>
</tr>
</table>
</body>
</html>
