Orbeon Xforms Error Broken pipe oxf：/config/prologue-servlet.xpl异常：java.io.IOException

我对Linux缺乏经验，所以请温柔地对待我。

我已经设置了运行Apache Tomcat的CentOS Web服务器。该服务器托管了一个使用Orbeon Xforms的ART-DECOR webapp。

我在使用Web应用程序时收到错误，该应用程序在WebApp日志文件中留下堆栈跟踪，请参阅下文。

我确信这个异常似乎是由Orbeon引起的，这引起了这个问题。

从我可以看出，这是一个问题，应用程序能够读取服务器端的XML文件，因为我在浏览器控制台时看不到任何Web调用。该文件似乎已到位所以我确信如果我的假设是正确的，这将是一个权限问题，但我不太了解Tomcat是否正确解析相对路径。

经过大量的挖掘和调试记录后，似乎ART-DECOR和Orbeon存在问题。我降级到Orbeon 3.9，这违反了ART-DECOR网站上的指示。

当ART-DECOR Web应用程序被置于DEBUG日志记录中时，我发现以下异常....
