各位高手请进,讨论这道有挑战性的异常!

[xmqds]

各位高手请看看这些代码哪里有错?
..............
Connection conn=DataSourceBean.getConnection();
OracleCallableStatement stmt = (OracleCallableStatement)conn.prepareCall("{call PK_RPT_COUNT_MRQK.sp_RPT_COUNT_MRQK(?,?,?,?,?)}");

..........................
执行后抛出ClassCastExceptiono异常:
OracleCallableStatement stmt = (OracleCallableStatement)conn.prepareCall("{call PK_RPT_COUNT_MRQK.sp_RPT_COUNT_MRQK(?,?,?,?,?)}");
就是这一句出错.其它都没错.

不知为什么?谢谢

CallableStatement stmt = conn.prepareCal("{call PK_RPT_COUNT_MRQK.sp_RPT_COUNT_MRQK(?,?,?,?,?)}");

少了个”l“，应该是
CallableStatement stmt = conn.prepareCall("{call PK_RPT_COUNT_MRQK.sp_RPT_COUNT_MRQK(?,?,?,?,?)}");
