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?
