tomcat 6.0 能启动 但是报错 显示404 tomcatmanager中 项目running为 false

正在学servlet我是跟着教程做的 没有 .html 跟 .jsp
整个项目其他的打开也全是404         
篇幅有限 这是启动tomcat时报错

解决办法

看上面的错误信息就知道是Servlet01项目里面的web.xml配置有问题

也就是这行

严重: Parse error in application web.xml file at jndi:/localhost/Servlet01/WEB-INF/web.xml
再看这行
java.lang.IllegalArgumentException: Invalid <url-pattern> LoadEmpServlet in servlet mapping
说web.xml里面的LoadEmpServlet 类那块配置有问题，检查url-pattern附近的xml配置就能解决
