Result set of One db to another DB

Question

Dear All,
Need your help.
I am posting my sample class below
public static java.sql.ResultSet getData(String dbConnectStr,String dbuserID,String dbpwd,String query) throws Exception
// Obtain default connection
// Query all columns from the EMP table
ResultSet rset = null;
Connection conn = null;
try
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
conn = (OracleConnection)DriverManager.getConnection("jdbc:oracle:thin:@"+dbConnectStr,dbuserID,dbpwd);
((OracleConnection)conn).setCreateStatementAsRefCursor(true);
stat.execute("alter session set NLS_DATE_FORMAT='DD-Mon-RRRR HH:MI:SS'");*/
System.out.println(query);
Statement stmt = conn.createStatement();
rset = stmt.executeQuery(query);
System.out.println("returning");
catch (SQLException e)
e.printStackTrace();
// Return the ResultSet (as a REF CURSOR)
return rset;
################################## My Function in Oracle DB
FUNCTION DB_CALL(dbConnectStr VARCHAR2,dbuserID VARCHAR2,dbpwd VARCHAR2,query VARCHAR2) return axsbcstatement.CUR is language java name 'com.axs.logc.OracleDeployProcedure.getData(java.lang.String,java.lang.String,java.lang.String,java.lang.String) return java.sql.Resultset' ;
########################### My Procedure Where i am calling this function
PROCEDURE INSERT_call (inward_dbConnectStr VARCHAR2,inward_dbuserID VARCHAR2,inward_dbpwd VARCHAR2,query VARCHAR2,updateCnt out number) as
up_cnt number(6) :=0;
db_cur axsbcstatement.inward_cur;
ENTRY_NMBR_field dummy_table.Entry_Nmbr%type;
SNDR_NAME_field dummy_table.Sndr_Name%type;

BATCH_TIME_field dummy_table.Batch_Time%type;
BEGIN
db_cur := INWARD_DB_CALL(inward_dbConnectStr,inward_dbuserID ,inward_dbpwd ,query);
loop
fetch db_cur into ENTRY_NMBR_field,TRAN_ID_field,SNDR_NAME_field,SNDR_ADDRSS_field,RCVR_NAME_field,REMARKS_field,TRAN_DATE_field,BNFCRY_field,BATCH_TRANID_field,BATCH_TIME_field;
EXIT WHEN db_cur%NOTFOUND;
begin
select ENTRY_NMBR INTO ENTRY_NMBR_field from dummy_table where ENTRY_NMBR = entry_nmbr_field and TRAN_ID = TRAN_ID_field;
if SQL%found then
dbms_output.put_line('Data Found in table ');
end if;
Exception
when no_data_found then
insert into dummy_table values(ENTRY_NMBR_field,TRAN_ID_field,SNDR_NAME_field,SNDR_ADDRSS_field,RCVR_NAME_field,REMARKS_field,TRAN_DATE_field,BNFCRY_field,BATCH_TRANID_field,BATCH_TIME_field);
up_cnt := up_cnt+1;
end;
end loop;
close db_cur;
updateCnt := up_cnt;
Exception
when others then
dbms_output.put_line(' - ' || SQLCODE|| ' ' ||SQLERRM);
END INSERT_call;
I am getting "ORA-00932: inconsistent datatypes: expected a return value that is a java.sql.ResultSet got a java.sql.ResultSet that can not be used as a REF CURSOR" this error while executing the procedure...
i have tried so many things but not able to solve this problem..
Apart from this If someone suggest me ...........
I am having two different database.with same table structure .
i have to take data from db1 and insert into the db2 on incremental basis (some checks required while inserting into the db2)
Regards .

Just modify your procedure like this
CREATE OR REPLACE PROCEDURE insert_call (
   inward_dbconnectstr         VARCHAR2,
   inward_dbuserid             VARCHAR2,
   inward_dbpwd                VARCHAR2,
   QUERY                       VARCHAR2,
   updatecnt             OUT   NUMBER
AS
   up_cnt               NUMBER (6)                      := 0;
   db_cur               axsbcstatement.inward_cur;
--   entry_nmbr_field     dummy_table.entry_nmbr%TYPE;
--   sndr_name_field      dummy_table.sndr_name%TYPE;
--   sndr_addrss_field    dummy_table.sndr_addrss%TYPE;
--   rcvr_name_field      dummy_table.rcvr_name%TYPE;
--   remarks_field        dummy_table.remarks%TYPE;
--   tran_amnt_field      dummy_table.tran_amnt%TYPE;
--   tran_date_field      dummy_table.tran_date%TYPE;
--   batch_tranid_field   dummy_table.batch_tranid%TYPE;
--   batch_time_field     dummy_table.batch_time%TYPE;
   all_rec              dummy_table.%ROWTYPE;
BEGIN
   db_cur := inward_db_call (inward_dbconnectstr, inward_dbuserid, inward_dbpwd, QUERY);
   LOOP
      FETCH db_cur
       INTO all_rec;
      EXIT WHEN db_cur%NOTFOUND;
      BEGIN
         SELECT entry_nmbr
           INTO entry_nmbr_field
           FROM dummy_table
          WHERE entry_nmbr = all_rec.entry_nmbr AND tran_id = all_rec.tran_id;
         IF SQL%FOUND
         THEN
            DBMS_OUTPUT.put_line ('Data Found in table ');
         END IF;
      EXCEPTION
         WHEN NO_DATA_FOUND
         THEN
            INSERT INTO dummy_table
                 VALUES (all_rec.entry_nmbr, all_rec.tran_id, all_rec.sndr_name, all_rec.sndr_addrss, all_rec.rcvr_name, all_rec.remarks, all_rec.tran_date,
                         all_rec.bnfcry, all_rec.batch_tranid, all_rec.batch_time);
            up_cnt := up_cnt + 1;
      END;
   END LOOP;
   CLOSE db_cur;
   updatecnt := up_cnt;
EXCEPTION
   WHEN OTHERS
   THEN
      DBMS_OUTPUT.put_line (' - ' || SQLCODE || ' ' || SQLERRM);
END insert_call;Regards,
