给大家说一下我的情况
TOMCAT-HOME=G:/tomcat
然后在webapps下面自己建立了一个工作目录zhukai,以下是server.xml的配置

             applications i.e. Contexts, place the interceptor inside of

然后在zhukai下面有一个WEB-INF目录,再下面是web.xml文件,如下:

在WEB-INF下面还有一个classes目录用来存放servlet我写的HelloWorldSevlet就放在下面


当我在浏览器中输入http://localhost:8080/zhukai/servlet/HelloWorldServlet的时候
怎么出现这样的错误:资源不允许(HTTP method is not supported by this URL).
