S'one tell me how to call Oracle Stored Proc from Java

Question

Hi,
I have a problem in calling the Stored proc using callable statement.It looks like we are doing the same thing or no..
Pl..let me know if you can correct me..Am enclosing the stored proc and java Code...
CREATE OR REPLACE PROCEDURE StoreFTPAddress (FTP in FTPTYPE) is
BEGIN
INSERT INTO DES.FTPSERVICE(
FTPID,
COMPANYID,
SERVERNAME,
DIRECTORY,
USERNAME,
PASSWORD,
INSTRUCTIONS)
VALUES( FTPID.NEXTVAL,
FTP.COMPANYID,
FTP.SERVERNAME,
FTP.DIRECTORY,
FTP.USERNAME,
FTP.PASSWORD,
FTP.INSTRUCTIONS);
END;
JAVA CODE :;
public String retrieveFormatExtension(String formatName)
OracleResultSet rs_form = null;
try
conn = ConnectionDataObjectImpl.getConnection();
Statement stmt = conn.createStatement();
String sql_retrieve = "{call retrieveFormatExtension} " ;
CallableStatement cst = conn.prepareCall(
"{call retrieveFormatExtension(?,?)}");
cst.setString(1," FName ");
cst.registerOutParameter(1, OracleTypes.VARCHAR); // OUT Parameter
cst.executeQuery();
rs_form = (OracleResultSet) cst.getObject(1);
cst.close();
catch (SQLException ex)
System.out.println("SQLException : " + ex.getMessage());
return null;

Syntactically it looks fine. Only thing is u r calling the proc with wrong name. Your procedure takes only one parameter and i.e
IN type. I think u need to correct ur preparecall statement.
