Calling PL/SQL API from OAF

Question

Hi all,
i have a stored procedure(xyz) in a package (abc) as below:
procedure xyz
(p_validate in boolean default false
,p_ptnl_ler_for_per_id out nocopy number
,p_csd_by_ptnl_ler_for_per_id in number default null
,p_lf_evt_ocrd_dt in date default null
,p_trgr_table_pk_id in number default null
,p_ptnl_ler_for_per_stat_cd in varchar2 default null
,p_ptnl_ler_for_per_src_cd in varchar2 default null
,p_mnl_dt in date default null
,p_enrt_perd_id in number default null
,p_ler_id in number default null
,p_person_id in number default null
,p_business_group_id in number default null
,p_dtctd_dt in date default null
,p_procd_dt in date default null
,p_unprocd_dt in date default null
,p_voidd_dt in date default null
,p_mnlo_dt in date default null
,p_ntfn_dt in date default null
,p_request_id in number default null
,p_program_application_id in number default null
,p_program_id in number default null
,p_program_update_date in date default null
,p_object_version_number out nocopy number
,p_effective_date in date) is
End;
In oaf i am calling this stored procedure in a function as below:
public String callToApi(String event_date, String event_name, String person_id) {
int ler_pk = 0;
int ovn = 0;
LifeEventIdVOImpl LifeEventIdVOObj = getLifeEventIdVO1();
LifeEventIdVOObj.setWhereClauseParams(null);
LifeEventIdVOObj.setWhereClauseParam(0, event_name);
LifeEventIdVOObj.executeQuery();
String ler_id = LifeEventIdVOObj.first().getAttribute("LerId").toString();
try {
OracleCallableStatement oracleCallableStatement = null;
OADBTransactionImpl txn =
(OADBTransactionImpl)getOADBTransaction();
String statement =
"BEGIN" + " abc.xyz(" +
" p_validate => :1" +
" ,p_ptnl_ler_for_per_id => :2" +
" ,p_csd_by_ptnl_ler_for_per_id => NULL" +
" ,p_lf_evt_ocrd_dt => :3" +
" ,p_trgr_table_pk_id => NULL" +
" ,p_ptnl_ler_for_per_stat_cd => 'DTCTD'" +
" ,p_ptnl_ler_for_per_src_cd => NULL" +
" ,p_mnl_dt => NULL" +
" ,p_enrt_perd_id => NULL" +
" ,p_ler_id => :4" +
" ,p_person_id => :5" +
" ,p_business_group_id => 0" +
" ,p_dtctd_dt => :6" +
" ,p_procd_dt => NULL" +
" ,p_unprocd_dt => NULL" +
" ,p_voidd_dt => NULL" +
" ,p_mnlo_dt => NULL" +
" ,p_ntfn_dt => :7" +
" ,p_request_id => NULL" +
" ,p_program_application_id => NULL" +
" ,p_program_id => NULL" +
" ,p_program_update_date => NULL" +
" ,p_object_version_number => :8" +
" ,p_effective_date => :9);" + " END;";
java.util.Date sysdate = new java.util.Date();
java.sql.Date today_date = new java.sql.Date(sysdate.getTime());
java.sql.Date life_event_date = new java.sql.Date(new java.util.Date(event_date).getTime());
oracleCallableStatement = (OracleCallableStatement)txn.createCallableStatement(statement, DBTransaction.DEFAULT);
oracleCallableStatement.setBoolean(1, Boolean.FALSE);
oracleCallableStatement.registerOutParameter(2, Types.INTEGER);
oracleCallableStatement.setDate(3, life_event_date);
oracleCallableStatement.setInt(4, Integer.parseInt(ler_id));
oracleCallableStatement.setInt(5, Integer.parseInt(person_id));
oracleCallableStatement.setDate(6, today_date);
oracleCallableStatement.setDate(7, today_date);
oracleCallableStatement.registerOutParameter(8, Types.INTEGER);
oracleCallableStatement.setDate(9, today_date);
oracleCallableStatement.execute();
ler_pk = oracleCallableStatement.getInt(2);
ovn = oracleCallableStatement.getInt(8);
System.out.println(ler_pk);
System.out.println(ovn);
catch (Exception e) {
e.printStackTrace();
return(ler_pk + "/" + ovn);
But i am getting an error as:
java.sql.SQLException: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'xyz' ORA-06550: line 1, column 7: PL/SQL: Statement ignored
But i think i have provided the right set of inputs...
Please have a look and let me know where i am wrong....
its urgent.. please reply asap

Shivam,
Use below code & let us know whether still throws the same error.
try
      Connection conn = getOADBTransaction().getJdbcConnection();
      CallableStatement cstmt = conn.prepareCall
      ("{call xyz  (:1, :2, :3)}");
      System.out.println("1" + Id);
      cstmt.setString(1,  IjpId);
      System.out.println("2" + EmpNum);
      cstmt.setString(2, EmpNum );
      System.out.println("3" + EmpPositionTitle);
      cstmt.setString(3, EmpPositionTitle );
      System.out.println("before calling");
      cstmt.execute();
      System.out.println("after calling");
      cstmt.close();
      catch(Exception e)
         String message = "Error in Data Saving: " + e;
         throw new OAException(message, OAException.ERROR);
      }Regards,
