jBPM6.3 + Hibernate4 + Tomcat7 + JPA2.0Exception：无法构建EntityManagerFactory

时间：2016-02-06 06:44:35

标签： eclipse hibernate jpa tomcat7 jbpm

我试图让this示例为我工作。由于我的jbpm版本是6.3.0.Final，所以this解决方案绝对不能解决我的问题。

我的情景是，首先，我创建了一个JPA＆amp;动态Web项目使用Eclipse Mars1，并将所有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。当我构建我的项目并运行独立的Tomcat 7.0.64而不是Eclipse内的服务器时，jsp出现没有任何问题，但当我点击create Process将触发TaskProcessServlet时，我收到一条错误消息：< / p> 

Error:[PersistenceUnit: org.jbpm.persistence.jpa] Unable to build EntityManagerFactory

我的postgresql-9.4.1207.jar（针对Tomcat8）会出问题吗？我不这么认为，因为我在Tomcat 8中一直遇到同样的错误，因此我将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？

非常感谢任何想法，非常感谢。

感谢Anton Giertli，感谢您的关注。

我修改了server.xml并通过引用here为JPA添加了hibernate.cfg.xml，解决了这个问题。

但我仍然需要找出相应的问题。

谢谢你。
