            OracleConnection con;
            OracleCommand cmd;
            OracleDataAdapter adpt;
            DataSet ds = new DataSet();
            string SP = "pckCurso.upCursosHabilitadosPAPws";
            con = new OracleConnection(ConfigurationManager.ConnectionStrings["bdradesanewConnectionString"].ConnectionString);
            cmd = new OracleCommand(SP, con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.Add("@numdle", SqlDbType.NChar, 16).Value = numeroDocumento;
            adpt = new OracleDataAdapter(cmd);
            con.Open();
            adpt.Fill(ds);
            con.Close();
