我正在使用Hibernate 4.3.11.Final和karaf 4.0.2开发一个项目。加载hibernate配置时，我得到以下异常，但是加载失败的类在bundle中。我希望有人可以帮我解决这个问题。我一直试图修复它好几天而且我的想法已经用完了。

经过进一步的故障排除后，我收到了另一篇帖子的评论，在Import-Package标签上包含了org.hibernate.internal.util。在此之后，原始问题得以解决。现在我有一个新的例外。然后异常说明找不到hibernate.cfg.xml文件，但是该文件位于异常中写入的位置“/config/hibernate.cfg.xml”

答案 0 :(得分：0)
我能够解决这个问题，形成某种原因，即使在卸载捆绑包之后，Karaf也会在旧的hibernate包上保留引用，因此karaf找不到hibernate配置文件。为了解决这个问题，我删除了karaf中的“data”目录以重新启动。然后我安装了所有依赖项，最后安装了我的bundle。然后在捆绑包上找到了正确启动的hibernate配置文件。
