SQL*Loader: Release 9.2.0.6.0 - Production on Wed Feb 7 08:58:05 2007

the part of OTLDatabase where it is showing error is

 public OTLDatabase(String _url, String _schema, String _user, String
_password) throws ClassNotFoundException, SQLException {
        url = _url;
        schema = _schema;
        user = _user;
        password = "car27max";

        logger.info("Connecting to " + url);
        logger.info("schema: " + schema);
        logger.info("user: " + user);
        logger.info("password: " + password);
        Class.forName("oracle.jdbc.OracleDriver");
        dbConn = DriverManager.getConnection(_url, _user, _password);
        metaData = dbConn.getMetaData();
    }
and that of CopyOneTable.java is

OTLDatabase target = new
OTLDatabase(AppVariables.get("targetdriver.url"),
AppVariables.get("targetSchemaPattern"),
AppVariables.get("targetUser"), AppVariables.get("targetPassword"));
OTLDatabase source = new
OTLDatabase(AppVariables.get("sourcedriver.url"),
AppVariables.get("sourceSchemaPattern"),
AppVariables.get("sourceUser"), AppVariables.get("sourcePassword"));

can anybody tell me how to remove this error??
