Google App Engine 500错误

所以我已经将我的应用程序部署到了GAE，但我得到的仅仅是一个简单的十字路口站点，在索引页面上有一个500错误。由于我根本就不是Java的专家，因此我需要一些解码错误日志的帮助。你知道该怎么做才能使应用程序再次工作（它一直在工作）？Google App Engine 500错误

这是告诉你，Jetty是失败的，因为有些应用程序正在使用的东西静态初始化期间发生异常。这导致后续类加载3210的失败。

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触发这些问题的静态初始化问题（可能含有堆栈跟踪）。

可惜的是，这是所有在GAE日志：/ – Elwhis

我发现有人发布了similar problem，因为我也有同样的问题。

他的解决办法，我引述如下：

我只是打了一下周围，似乎这个问题是JAXB的IMPL （组com.sun.xml.bind）。版本2.1.12作品（是啊！），版本2.2.4（最新）上 App Engine的生产不起作用

非常感谢你离职后的工作后3天内解决我的问题。我目前正在使用声明API。默认情况下，字正腔圆1.25不使用JAXB 2.1.12，所以我得到了同样的错误......通过重写我的pom.xml \t \t \t \t \t com.sun.xml.bind \t \t \t jaxb- IMPL \t \t \t 2.1.12 \t \t我得到它的工作！ –

我有类似的堆栈跟踪，但做了一些研究之后，我意识到进样器是通过jersey-json项目的Maven传递依赖项包含在我的项目中的jaxb-impl库中。我排除了jaxb-impl库，重建并重新部署了该问题。 JAXB由JDK6提供，因此您可能遇到同样的问题。

我得到了同样的错误，它走了，当我在web.xml文件中禁用WADL（见的servlet类标签下的init-PARAM节）。日志暗示了这一点，在崩溃前您可以看到wadl参考。我做了这个改变并重新启动，它工作。

<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>
