WebLogic下开发Hibernate问题 java.lang.NoSuchMethodError:javax.persistence.OneToMany.orphanRemoval()Z

org.springframework.beans.factory.BeanCreationException: Errorcreating bean with name 'sessionFactory' defined in ServletContextresource [/WEB-INF/classes/spring-

base.xml]: Invocation of init method failed; nested exception isjava.lang.NoSuchMethodError:javax.persistence.OneToMany.orphanRemoval()Z

【注】：上述问题在于Hibernate的包冲突或者没有被加载到。

       解决办法：把工程中hibernate-jpa-2.0-api-1.0.0.Final.jar包拷贝到

                 D:\bea\jdk160_11\jre\lib\ext 目录下。
