Problems with ResultSet

[Enrique Prados Valiente]

Hi! 
I'm using Tomcat and JSP but there are problem, my JSP don' work.....
I have this code in my JSP
(code.....)
Statement 
s=cn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);

(more code........)


           if (!rs.isFirst()) rs.previous(); 

              %><tr> 
              <td><%=rs.getString(1)%></td><%

           }

(more code........)

In begin of my JSP there is this code line <%@ page language="java" 
import="java.sql.*,java.io.*,java.util.*" %>

but when I run the server and JSP, it appears this error


        [Microsoft][ODBC Driver Manager] Invalid cursor state


I think that Jsp fails in this code line,             <td><%=rs.getString(1)%></td><%


                               
Can anyone out there help me? 
Thanks in advance, 
Enrique.
