有关jDBC调用存储过程

Session session = HibernateUtils.getSession();
String sql = "{call transition (?,?,?,?,?,?,?,?,?,?)}";
CallableStatement call = null;
......
call.setBigDecimal("p_balance", accinfoctrol.getBalance());// 余额
call.setBigDecimal("p_scale", accinfoctrol.getInitproportion());// 初始保证金比例
call.setInt("p_accountid", accinfoctrol.getId().getAccountid());// 帐户序号
call.setInt("p_chfg", accinfoctrol.getId().getChflag());// 钞汇标志
call.setString("p_currency", accinfoctrol.getId().getMargcurrency());// 保证金币种
call.setString("p_OrderId", rskinform.getOrderid());// 订单号
call.setInt("p_changeFlag", rskinform.getChangeflag());// 变动标志
call.setInt("p_ModiFlag", rskinform.getModiflag());// 更改标志
call.setInt("p_transactFlag", rskinform.getTransactflag());// 处理标志
call.registerOutParameter("publicreturn", -1);为什么这样写，数据都已经影响了数据库，而会抛出异常呢？
