Hibernate_c3p0_报错_AbstractMethodError:OracleConnection.getHoldability()I

 

 

错误日志如下 ：

 

2010-07-15 12:04:29,097 [com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#2] WARN  com.mchange.v2.c3p0.impl.NewPooledConnection - oracle.jdbc.driver.OracleConnection@10c0fa7 threw an Error when we tried to check its default holdability. This is probably due to a bug in your JDBC driver that c3p0 can harmlessly work around (reported for some DB2 drivers). Please verify that the error stack trace is consistentwith the getHoldability() method not being properly implemented, and is not due to some deeper problem. This message will not be repeated for Connections of type oracle.jdbc.driver.OracleConnection that provoke errors of type java.lang.AbstractMethodError when getHoldability() is called.

可以看出可能是Oracle的驱动问题。

但是不影响使用。

It's not an error, it's a warning. I don't really know anything about the Oracle driver, but I'm sure the Oracle forums probably have threads on this issue. I'd guess the method simply isn't implemented hence the message.
