解决方案三：
看看有没有重复的包或者少包
解决方案四：
引用2楼aqqbjlgu的回复:
看看有没有重复的包或者少包
org.hibernate.annotations.Entity这个类在hibernate3.jar包里是有的。
解决方案五：
有没有重复的包？
解决方案六：
弄了好几天。把hibernate-jpa-2.0-api-1.0.1.Final.jar包重命名为javax.persistence_1.0.0.0_1-0.jar然后覆盖到D:bea103modules（weblogic安装目录）目录下就正常了，不知道是什么原因呢？

是不是hibernate-jpa-2.0-api-1.0.1.Final.jar和javax.persistence_1.0.0.0_1-0.jar有相同的Entity类导致调用混淆了
解决方案十：
你hibernate2的jar都完全删除了吗？在工程里面搜一下，看org.hibernate.annotations.Entity这个class文件有几个？如果有多个，系统就不知道找哪一个，报找不到错误了。
解决方案十一：
什么情况？我也遇到了这个问题，求合理的解决方法
