I guess I overlooked that restriction in the original e-mail. A form is a
good way to handle it although the info still would be viewable in the page
source. Rahul, you could also just pass back the value of 'i' to the jsp
and retrieve the categoryId in the JSP based on the index. Or you can
return the Category name that you already display as a query param and look
up the category ID back in the JSP.

The original task was not to show categoryID to users. I think it's
silly, but...
Try using an HTML form with a categoryID field and POST method and
modify categoryID value in onclick() handler, something like this:
<form name=catIDform action="CategoryMaint.jsp">
<input type=hidden name=catID>
...
<% ... loop ... %>
...
<A href="#" onClick="catIDform.catID=<%= Categories[i][1] %>;
catIDform.submit(); return false;"> <%= Categories[i][0] %> </A>
...
<% ... end loop ... %>
...
</form>
I think it helps.
