java - getting Invalid column index when calling Procedural -


i have procedural takes 2 string arguments , returns integer value database oracle 10g .

when try print out result i'm getting invalid column index .

the code 

  try {                dbconnection newconnect = new dbconnection();              connection con = newconnect.makeconnect();              callablestatement stmt1 = ((connection) con).preparecall("{ call login (?, ?, ?)}");             stmt1.registeroutparameter(1, types.integer);             stmt1.setstring(2, "ahmed");             stmt1.setstring(3, "ahmed");               resultset rslt = stmt1.executequery();               if (rslt.next())              {                   system.out.println( rslt.getint(1));               }

procedural login 

   create or replace      procedure login          (p_username  teacher.username%type,                     p_password  teacher.password%type)                  v_teacher_id   teacher.teacher_id%type;                       v_username    teacher.username%type ;            v_password     teacher.password%type ;       begin select   teacher_id, username , password    v_teacher_id , v_username , v_password    teacher   username = p_username , password =p_password  ;              dbms_output.put_line (v_teacher_id);         end login ;

nice try error exists here.... this... output retrive 100% sure.

create or replace procedure login  (           v_teacher_id out teacher.teacher_id%type,                     p_username  in teacher.username%type,                     p_password  in teacher.password%type)     ..... (blah blah blah)

tell me onething, if not providing output parameter @ start of procedure , how can expect output in java code ?

now try, output java code 

 rslt.getint(1)

all best :)... surajit
