JDBC Adapter - Sender - Stored Procedure - SQLException Error

Question

Hi,
     I have created one stored procedure in our Oracle database. I give below that stored procedure.
CREATE OR REPLACE PROCEDURE sp_stud
IS
    l_row student%ROWTYPE;
    TYPE t_ref_cursor IS REF CURSOR RETURN l_row%TYPE;
    c_cursor t_ref_cursor;
BEGIN
    OPEN c_cursor FOR
     SELECT *
     FROM student where readflag= ' ';
    LOOP
     FETCH c_cursor into l_row;
        EXIT WHEN c_cursor%NOTFOUND;
        DBMS_OUTPUT.PUT_LINE(l_row.id || ' : ' || l_row.name);
    END LOOP;
close c_cursor;
END;
This is a procedure to retreive rows from the table student which is having the field read_flag = ' '; (Student table contains the fields ID, NAME, BIRTHYEAR, BIRTHMONTH, READFLAG).
In JDBC Sender Adapter, I set the values for the following fields under Parameters tab.
Query SQL Statement: EXECUTE sp_stud
Update SQL Statement: UPDATE student SET readflag = 'Y' where readflag = ' '
The scenario is every 5 minutes JDBC adapter checks the table whether any new row is inserted, if it is inserted and commit, it will send that record to File. This is the Scenario.
In Runtime Workbench, Communication Channel Monitoring, it shows the following error, when JDBC Polls the table.
Database-level error reported by JDBC driver while executing statement 'EXECUTE sp_stud'. The JDBC driver returned the following error message: 'java.sql.SQLException: ORA-00900: invalid SQL statement '. For details, contact your database server vendor.
Note : If we execute the Stored Procedure ad SQL command level, it works fine.
Kindly help friends to solve this, where the error is happened.
Thanking you,
Kind regards,

Hi,
Not a Database expert. But , in case you have not seen the note pointed by Deepu,
<i> The JDK 1.1.x, 1.2 and 1.3 versions (classes111. zip, classes12.zip, classes12.jar) of the driver are not compatible with the SAP XI JDBC Adapter. Use the JDK 1.4 driver (ojdbc14.jar) instead. For details, refer to Oracle MetaLink note # 203849.1.
           <b>Invoking Oracle stored procedures from within a JDBC sender channel is only possible for Oracle DBMS versions >= 10.2.x using so-called table functions:</b>
           Example:
pkg1 -
CREATE PACKAGE pkg1 AS
  TYPE numset_t IS TABLE OF NUMBER;
  FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED;
END pkg1;
CREATE PACKAGE BODY pkg1 AS
-- FUNCTION f1 returns a collection of elements (1,2,3,... x)
FUNCTION f1(x NUMBER) RETURN numset_t PIPELINED IS
  BEGIN
    FOR i IN 1..x LOOP
      PIPE ROW(i);
    END LOOP;
    RETURN;
  END;
END pkg1;
pkg1 -
        <b>   This function has to be invoked from the sender channel configuration (SELECT statement) as follows:
           SELECT * FROM TABLE(pkg1.f1(5));</i></b>
Check this, confirm your Oracle DB version and then use the Table Functions as described in this note.
A Database Expert wil be able to crack this for sure.
