jBPM6.3+Hibernate4+Tomcat7+JPA2.0异常：无法构建EntityManagerFactory
jBPM6.3+Hibernate4+Tomcat7+JPA2.0Exception: Unable to build EntityManagerFactory
我试图制定 this example work for me. Since my jbpm version is 6.3.0.Final, so this 解决方案绝对不能解决我的问题。
我的场景是，首先，我使用Eclipse Mars1创建了一个JPA & Dynamic Web Project，将所有的示例文件复制到我的新项目中，然后修改TaskProcessServlet.java，如下所示，因为原始 servlet 代码中 Runtime 部分的过时和弃用。当我在 Eclipse 内部的服务器以外的独立 Tomcat 7.0.64 上构建我的项目和 运行 时，jsp 毫无问题地出现了，但是当我单击 create Process 时将触发 TaskProcessServlet，我收到一条错误消息：
Error:[PersistenceUnit: org.jbpm.persistence.jpa] Unable to build EntityManagerFactory
我的 postgresql-9.4.1207.jar(for Tomcat8) 会有问题吗？我不这么认为，因为我在 Tomcat 8 中一直遇到同样的错误，所以我将 Tomcat 从 8.0.30 降级到 Tomcat 7.0.64。
我可以在 Tomcat 8 和 7 上从 JBOSS 运行 jbpm-console。这个 jbpm-console 会干扰我的项目吗？
如何解决这个问题？
任何想法将不胜感激，非常感谢。

谢谢 Anton Giertli，感谢您的关注。

修改了我的server.xml并为JPA添加了hibernate.cfg.xml后解决了这个问题
但我还有一些后续问题需要解决。
