hibernate 3.5.6 annotation 双向一对多的配法

今天用hibernate 3.5.6 annotation 双向一对多时候出现了异常，Invocation of init method failed; nested exception is java.lang.NoSuchMethodError:javax.persistence.OneToMany.orphanRemova()Z

上网一查发现是ejb3-persistence.jar的问题，解决方法是去掉ejb3-persistence.jar，使用hibernate-jpa-2.0-api-1.0.0.Final.jar

现贴出我自己的配法


一方（课程库）：Course.class
