Hi,
you surely would need a good tutorial for jdbc and one for sql.
                    sqlI="Insert into Pro"
                    +"(Prod_Id)"
                     +"values('"+txtProd_Id+"')";      
                  txtProd_Id.setText("");     Please use prepared statements that concated sql strings
                    rs=stmt.executeQuery(sqlI);
                    //rs=stmt.executeUpdate(sqlI);
                    while (rs.next()) {
                  txtProd_Id.setText(rs.getString(1));
               }You must be joking here. Statement.executeQuery is used for SELECTing data. You insert statement is never going to return a resultset. ExecuteUpdate, which you have commented by the way, does the job but it returns an int(RecordsAffected).
