URGENT !( jdbc query problem)

Question

Hi Forum
i made an application which run on JRun server.
In many of my jsps i used sql query like this:
" select id, name, rollno from student where add = 'jj';"
and retrieve the record from resultset like this:
rs.getString("id");
rs.getString("name");
rs.getString("rollno");
I got no error.
BUT WHEN I RETRIEVE THE RECORDS LIKE THIS
rs.getString("name");
rs.getString("id");
rs.getString("rollno");
i got the error:
java.sql.SQLException: [Oracle][ODBC]Invalid column number <1>.
I can not understand what is the problem ?
all the datatypes are correct.
all coding is correct.
and everything is correct.
pls help me & suggest a solution.
is there any problem of jdbc API OR of JRUN SERVER SETTINGS?
thanks

Here is a part of my code in which i got error:
(all variables are defined)
It is the working code. BUT when i change the sequence of retrieving fields as i select then problem occurs.
pls help me, i need it urgently.
if(st.equals("YES")){
          rs=stmt.executeQuery("select r.na_WPN, m.MK_WPN, m.tp_WPN, m.REC_NO, m.ISSUED, r.dte_del, r.ps from amm_issue r,armentry m where r.ent_srno=m.srno and r.ps='"+username+"' and m.issued='YES' ");
     else if(st.equals("NO")){
                    rs=stmt.executeQuery("select r.na_WPN, m.MK_WPN, m.tp_WPN, m.REC_NO, m.ISSUED, r.dte_del, r.ps from amm_issue r,armentry m where r.ent_srno=m.srno and r.ps='"+username+"' and m.issued='NO' ");
     else if(st.equals("BOTH")){
          rs=stmt.executeQuery("select r.na_WPN, m.MK_WPN, m.tp_WPN, m.REC_NO, m.ISSUED, r.dte_del, r.ps from amm_issue r,armentry m where r.ent_srno=m.srno and r.ps='"+username+"'");
while(rs.next())
     String tp_wpn=rs.getString("na_WPN");
     String mk_wpn=rs.getString("MK_WPN");
     String no_wpn=rs.getString("tp_WPN");
     String rec_no=rs.getString("REC_NO");
     String issued=rs.getString("ISSUED");
     dte_del          =rs.getString("dte_del");
     ps=     rs.getString("ps");
          if(i==0){
          out.println("<tr><th>Police Station </th> <th>Type of Weapon</th><th>Make of Weapon</th><th>No of Weapon</th><th>Recipt No</th><th>Issued Status</th><th>Date of Receiving");
          }i++;
          out.println("<TR><td>"+ps+" <td>"+no_wpn+"      <td>"+mk_wpn+"</td> <td>"+tp_wpn+"</td> <td> "+rec_no+"</td><td>"+issued+"<td><center>"+dte_del+" </td>");
