Eclipse上的Tomcat服务器“ HTTP状态404”，在Windows上运行良好

Question

我对所有服务器事物都还很陌生，所以如果我没有足够的知识来正确解释这种情况，请原谅。

基本上，我从Windows计算机运行Tomcat服务器，并且运行正常，我在localhost看到了欢迎页面。 但是，当我尝试部署项目并使用Eclipse运行它时，看到HTTP Status 404错误。

到目前为止，我已经在Internet上阅读了很多文章和意见，其中一些我不太了解，但是我尝试的是切换服务器的位置。 但是，当我这样做时，控制台中会出现一些严重错误，并且我无法重新启动服务器，除非我重新启动Eclipse本身。

这是完整的堆栈跟踪：

我将不胜感激，但是，正如我所说，对于servlet来说我还很陌生，如果无法正确解释某些内容，我感到很抱歉。

我正在使用Eclipse Luna和Tomcat 8.0版本。

Answer 1

它说文件webproject.filecounter无效。 也许您可以尝试删除。 元数据。
