java.lang.AbstractMethodError: com.microsoft.jdbc.

今天在连spring2.5 和 hibernate3.2的时候报了下面错误

java.lang.AbstractMethodError: com.microsoft.jdbc.sqlserver.SQLServerConnection.getHoldability()I
	at com.mchange.v2.c3p0.impl.NewPooledConnection.carefulCheckHoldability(NewPooledConnection.java:117)

后来发现我从spring2.5中取的C3P0JAR包，与HIBERNATE中提供的不一致，换了就好 了
