hibernate用c3p0报错

错误信息如下：
Caused by: java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Can't start a cloned connection while in manual transaction mode.

解决办法：将

	<property name="hibernate.connection.url">
			jdbc:microsoft:sqlserver://loaclhost;DatabaseName=t		</property>

改为：

	<property name="hibernate.connection.url">
			jdbc:microsoft:sqlserver://localhost;DatabaseName=t;SelectMethod=Cursor
		</property>
