don't know sure shouldn't hssfrow row= sheet.createrow((short)0); inside while loop? create new row every result?

edit:

                     statement stmt = conn.createstatement();       string filename="c:/users/sangu/downloads/data.xls" ;      hssfworkbook hwb=new hssfworkbook();      hssfsheet sheet =  hwb.createsheet("sheet");            resultset res = stmt.executequery("select * login ");          while (res.next())         {                      hssfrow row=   sheet.createrow((short)0);              string cg = res.getstring(1);              string cd = res.getstring(3);              row.createcell((short) 0).setcellvalue(cd);      row.createcell((short) 1).setcellvalue(cd);      row.createcell((short) 1).setcellvalue(cd);                              %>              <tr>              <td align="center"><%=cg%></td>              <td align="center"><%=cd%></td>              </tr>             <%      fileoutputstream fileout =  new fileoutputstream(filename);      hwb.write(fileout);      fileout.close();      out.println("your excel file has been generated!");                     hwb.write(response.getoutputstream()); }
