java – localhost上的服务器tomcat v8.0服务器无法启动

我的web.xml文件似乎有问题.
每次运行Apache tomcat 8服务器时,都会出现此错误：
localhost上的服务器tomcat v8.0服务器无法启动.

当我删除xml文件的servlet时,服务器工作了!!
我的web.xml如下：

<?xml version="1.0" encoding="UTF-8"?>

任何建议让它工作而不删除xml文件的代码？

先谢谢你们.

解决方法

这个问题的一个原因是web.xml文件中的问题……

我也遇到了这个问题,我解决了.

步骤解决此问题：

1-检查每个servlet类名是否正确(完全限定类名)

2-如果检查正确的类名,请按类名按ctrl并在该类名上移动指针,如果类名给出超链接,则类名是正确的,否则你必须用适当的类名更改.

你在项目中添加的3-检查jar是正确和有效的

4-所有这些更改后刷新项目并运行它..

有用….
