使用MyEclipse创建JavaEE5.0的Web项目，在使用Hibernate3.5.1/3.6等版本的注解功能时出现错误：java.lang.NoSuchMethodError:javax.persistence.OneToMany.orphanRemoval()Z


关键的原因是:引用的库文件存在版本冲突,很可能是因为javaee.jar中的部分类与hibernate-jpa-2.0-api-1.0.0.Final.jar存在版本冲突
解决办法:删除对Java EE 5 Libraries的使用,如果这个办法用了还是照旧产生这个问题的话..那就是引入的包里得部分类也存在版本冲突,很可能是ejb3-persistence.jar,把它删除..再部署运行...OK..问题应该没了
