I'm using IntelliJ Idea 9, properly attached hibernate-jpa-2.0-api-1.0.0.Final.jar
I've invalidated the cache, deleted out/war folders but still having an error at the compile time.
我正在使用 IntelliJ Idea 9，正确附加hibernate-jpa-2.0-api-1.0.0.Final.jar
我已经使缓存无效，删除了 out/war 文件夹，但在编译时仍然有错误。

I use IntelliJ as well and hibernate-jpa-2.0-api-1.0.0.Final.jar and javax/persistence/Table.class and javax/persistence/ManyToOne.class are definitely in this JAR.
我也使用 IntelliJ，并且 hibernate-jpa-2.0-api-1.0.0.Final.jar 和 javax/persistence/Table.class 和 javax/persistence/ManyToOne.class 肯定在这个 JAR 中。
I can only think that the JAR is not in your classpath. Where have you placed this JAR? What are you using to try compile your code? Are you certain it is in your classpath?
我只能认为 JAR 不在您的类路径中。你把这个 JAR 放在哪里了？你用什么来尝试编译你的代码？你确定它在你的类路径中吗？

Unfortunately I do not have my dev. environment here but as far as I remember hibernate jar does not necessarily contain the JPA stuff, so you have to add the persistence.jar to your classpath.
不幸的是，我没有我的开发人员。环境在这里，但据我所知，hibernate jar 不一定包含 JPA 的东西，所以你必须将 persistence.jar 添加到你的类路径中。
BTW try to use maven as a build tool and forget about resolving dependencies between third party libraries.
顺便说一句，尝试使用 maven 作为构建工具而忘记解决第三方库之间的依赖关系。
