HTML JSP HREF parameters

Most likely a dumb question, but I am week in this area.
I have a table which is generated dynamically in my jsp as I do a jdbc
query. I have created an anchor
<TD><A><HREF="<%bean.getValue()%>?id=rs.getID()%>. ..I believe the
value is posted, since I move my mouse on top of the field and it
displays the right value....but where? I need to know which API I
should use to read id (HTTPServletRequest.getxxx?)
Thank you very much.
