How do I pass a variable from one jsp to another?

[Bradly Fackrell]

For example: Say I've set the ID of btnDelete equal to the variable custID. When I click btnDelete I'd like to push that variable to the next page.

<form action="deletedCustomerRRE.jsp" method="post" name="frmDelete" target="mainFrame" id="frmDelete">
  <label>
    <input name="btnDelete" type="submit" id="<%= custID %>" value="Delete" />
  </label>
</form>

To shed some light on why I'm not simply using request.getParameter: I'm filling a table with data from a database (Something similar to a data grid in ASP.NET) One of my columns has a 'Delete' button; when I select any given delete button I want to delete that row of data. This is how I've built my table:

<table>
	<th>Delete</th> <th>Update</th> <th>Customer ID</th>.....
	<% rset = stmt.executeQuery("SELECT * FROM customer ORDER BY lastName"); %>
	<% while (rset.next()) { %>
	<% String custID = rset.getString(1); %>
		<tr> 		
			<td>
			<form action="deletedCustomerRRE.jsp" method="post" name="frmDelete" target="mainFrame" id="frmDelete">
				<label>
					<input name="btnDelete" type="submit" id="btnDelete" value="Delete" />
				</label>
			</form>
			</td>
			// Update button goes here...
			<td><%= custID %></td>
			<td><%= rset.getString(2) %></td>
			<td><%= rset.getString(3) %></td>
			...
		</tr>
	<% } %>
</table>

So while I build my table I can set the custID variable to something like the id of the 'Delete' button or in a hidden text box.

I don't know, maybe this is all real "Hokey" but it's the best that I can come up with....

Put a hidden input with the value in the form.

Two other things:

Putting a button inside a label is really weird.

Java in a JSP is a very very poor practice that's been discredited for almost 10 years now. Time to get down with modern techniques...

Scarry since that is how my instructor is teaching it....

Anyway, I've been working on this to the point where I can't think straight. From what I've read; it seems like I should be doing this through a function but I haven't been able to put that together.

oi!

Oh well, when you're out on your own, know that things have moved on quite a bit...

Can't think of any reason that you need anything but a hidden input.

I don't know why I was fighting the hidden field route. After some sleep I tried that again with success.

Thanks Bear!
