Callable Statement throws exception..pls help

Question

When I use Callable Statement calling my function which returns Y if person is employee or nothing if not I get this error..
Procedure not createdORA-06550: line 1, column 22:
PLS-00103: Encountered the symbol "CHCK_EMP_STATUS" when expecting one of
the following:
. ( * @ % & = - + ; < / > at in mod not rem
<an exponent (**)> <> or != or ~= >= <= <> and or like
between is null is not || is dangling
The symbol "." was substituted for "CHCK_EMP_STATUS" to continue.
Here is my code..
import java.sql.*;
import java.io.*;
public class FunctionTest
     public static void main(String args[])
          Connection conn = null;
          CallableStatement stmt = null;
          ResultSet rs=null;
     try
     Class.forName("oracle.jdbc.driver.OracleDriver");
     conn = DriverManager.getConnection("........");
     stmt = conn.prepareCall("{call function chck_emp_status(?,?)}");
          stmt.setString(1,"137897");
          stmt.registerOutParameter(2,Types.VARCHAR);
          stmt.execute();
          String s = stmt.getString(1);
          stmt.close();
          conn.commit();

          }//try
          catch(Exception e)

Answer 1

This is the function
CREATE OR REPLACE function chck_emp_status (id number) return varchar2
as
emp_id          number;
results          varchar(2);
cursor emp_status is
     select id
     from emp
     where emp_status = 'A'
and emp_id = id;
begin
     open emp_status;
     fetch emp_status into emp_id;
     if emp_id%notfound THEN
          results := '';
     else
          results := 'Y';
     end if;
     close emp_id;
     return results;
end;
