我需要一些帮助来解决为什么我的持久性单元没有使用Hibernate在Karaf中加载。日志文件报告
Bundle com.vogelware.simple.remote.combined is waiting for dependencies [(&(&(org.apache.aries.jpa.proxy.factory=true)(osgi.unit.name=person)(objectClass=javax.persistence.EntityManagerFactory))].
我认为问题是EntityManagerFactory服务没有运行。基于SO消息Jpa-hibernate error while starting the service，所有必需的服务都在运行。见下文。
我已经尝试在hibernate bundle之前启动我的持久性bundle，但是会得到相同的行为。
下面列出了数据源，持久性和persistence.xml的蓝图。
有关如何运行此简单示例的任何建议吗？

答案 0 :(得分：2)
你很可能在aries jpa中遇到错误。你能试试karaf 3.0.2吗？它包括较新的白羊座jpa功能。你还应该检查你是否只加载了jpa 2.1 api。如果你有jpa 2.0和2.1 apis加载它将无法正常工作。
