所以我已将我的应用程序部署到GAE，但我得到的只是索引页面上的500错误，这只是一个简单的十字路口网站。由于我根本不是Java的专家，因此我需要一些解码错误日志的帮助。 你有什么想法让应用程序再次运行（它已经工作）了吗？

我遇到了同样的错误，当我在web.xml文件中禁用WADL时它就消失了（参见servlet-class标签下的init-param节）。日志暗示了这一点，你会在崩溃前看到wadl引用。我做了这个改变并重新启动，它运作了。
<servlet>
<servlet-name>jerseywebapp</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.feature.DisableWADL</param-name>
<param-value>true</param-value>
</init-param>

我找到了发布了similar problem的人，因为我也遇到了同样的问题。
他引用的解决方案：
我只是玩了一下，似乎问题是jaxb-impl （group com.sun.xml.bind）。 版本2.1.12工作（是啊！），版本2.2.4（最新）不起作用 App Engine制作
答案 2 :(得分：1)
我有类似的堆栈跟踪，但在做了一些调查后，我意识到Injector通过jersey-json项目的Maven传递依赖项被包含在我的项目中的jaxb-impl库中。我排除了jaxb-impl库，重建并重新部署并解决了问题。 JAXB由JDK6提供，因此您可能遇到同样的问题。

它告诉你Jetty失败了，因为你的应用程序正在使用的一些东西在静态初始化期间抛出异常。这导致后续类加载失败com.sun.xml.bind.v2.runtime.reflect.opt.Injector。
不幸的是，这些消息中没有显示问题的根本原因。
您需要检查日志文件以查找之前的条目（可能带有堆栈跟踪），该条目报告触发这些条目的静态初始化问题。
