Hi Nic,
Thanks for the reply. My problem is, and maybe I'm over-thinking this
thing, is that my query results are dynamically produced. My result table
looks like this:
Cost Center Minutes Total Cost
606998 34.8 226.20
440500 23.4 152.10
etc...
with the "Cost Center" field being a dynamically-created <A HREF> link to
another servlet which drills down the data to query on all the records
specific to that cost center only. I need a way to pass the value, say
"606998" to a servlet that will query on that value. Since the <HREF> does
not have a specific "value" or "name" field, as does say, a text box, how do
I do this? Remember, I could have up to 100 or more records. How does the
servlet know from the id in your example that that is a parameter name?
Isn't that just text on the screen?

You mean you have something like this:
<table>
<tr>
<td>id</td>
<td>name</td>
<td>phone</td>
</tr>
<tr>
<td><a href="/query/?id=1">1</a></td>
<td>nic</td>
<td>8238 728 92783</td>
</tr>
>How do I pass the value of the link to a servlet
>that just serves up queries based on that value?
You just ensure that the link points to the servlet mapping.
In the example above the following would be used in your deployment
descriptor:
<servlet>
<servlet-name>query servlet</servlet-name>
<servlet-class>com.nic.QueryServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>query servlet</servlet-name>
<url-pattern>/query/*</url-pattern>
</servlet-mapping>
And the servlet would look like this:
public class QueryServlet
extends HttpServlet
{
public void doGet(...
{
String idStr=request.getParameter("id");
int id=Integer.parseInt(idStr);
//do query on id
.
.
.
PrintWriter out=response.getWriter();
out.println("<table><tr><td>id</td><td>name</td>....
out.println("<tr><td><a
href=\""+request.getServletPath()+"\">"+id+"</a></td>");
.
.
.
}
Ok?
