Tomcat 8抛出错误：'启动时子容器失败' [英] Tomcat 8 throws error : 'A child container failed during start'

问题描述

我一直在处理计算机上的代码并将该代码导入到其他计算机上。但是当我部署代码并在另一台机器上运行时，tomcat无法正常启动并抛出错误。

I have been working on a code on my computer and imported that code on other machine. But when I deploy code and run it on the other machine, tomcat doesn't start properly and throws error.

我试过其他解决方案对于Stack Exchange上的同样问题。但没有什么对我有用。

推荐答案

似乎导致类 com.sun.faces.config .ConfigureListener 存在于您的计算机中但不存在于目标计算机中。此类通常属于 jsf-impl.jar 或 jsf-ri.jar 库。

It seems that the causing class com.sun.faces.config.ConfigureListener is present in your computer but not in the target machine. This class usually belongs to jsf-impl.jar or jsf-ri.jar libraries.

由于你在两台机器上部署相同的战争（我假设），这些库显然没有进入战争，因此它们可能会进入你的计算机的Tomcat运行时：在目录中查找它< tomcat> / lib 并将其复制到目标机器的Tomcat lib目录中。

Since you are deploying the same war (I assume) on both machines, that libraries are obivously not into the war, so they are likely to be into your computer's Tomcat runtime: Look for it in directory <tomcat>/lib and copy it into the target machine's Tomcat lib directory.
