Question

我正在尝试为最终的uni项目制作一个在Eclipse-ee的apache tomcat v8.0服务器上运行的动态Web应用程序，并且无法启动服务器。它一直运行良好，然后似乎无故停止。我是整个Web应用程序的新手，所以如果我做过任何愚蠢的事，请提前道歉！

这是尝试启动服务器时收到的错误消息：

这是服务器概述选项卡：

这是我尝试启动服务器时的控制台输出。有一些错误，但我不明白它们的含义：

最后是web.xml文件。我让它保持不变，所以我希望这很好：

Answer 1

我相信这是问题所在

由于：java.lang.IllegalArgumentException：名为的servlet [LoginCheck]和[Registration]都映射到url-pattern [/ LoginCheck]不允许

将servlet更改为具有2个单独的路径。

Answer 2

您有多个servlet映射到同一URL：

Caused by: java.lang.IllegalArgumentException: The servlets named [LoginCheck] and [Registration] are both mapped to the url-pattern [/LoginCheck] which is not permitted

可能是复制粘贴错误，可能您应该更改Registration的URL

Tomcat v8.0服务器无法启动
