java - 无法启动服务 jboss.deployment.unit - StartException

Question

我对 Web 应用程序还很陌生，但我正在尝试使用我对 Web 应用程序的(非常)基本理解来修复以前可以运行的应用程序。此应用程序是由我无法再寻求帮助的其他人构建的。我希望你能给我指出正确的方向。使用谷歌几天后，我仍然没有找到解决方案。

我正在使用 Jboss 7 和提供的 jboss-eap 运行时服务器。安装的 JDK 是 1.7.0_60(由于其他程序拒绝使用较新版本...)；但是，我在使用 JDK 1.8.0_20 时遇到了同样的问题。我还使用 Maven 3.0.4 和 Hibernate(找不到哪个版本)。

应用程序似乎几乎完全部署，但最后我收到 StartException 错误和几个原因(Nullpointers 和 IllegalState)。我不知道去哪里看。 Hibernate 配置有问题还是其他问题？

非常感谢任何帮助!如果您需要更多信息，请询问。(因为我是新手，我希望你能非常具体地说明在哪里可以找到某些文件等)。

问候，世纪

我已经解决了这个问题，这是一个导致空对象的数据库问题，这导致了初始的 NullpointerException。其他异常是 Nullpointer 的结果。填充对象后，war 正确部署。
