我已经创建了一个Eclipse动态Web项目在本文档中提及的网址模式:sampledoc抛出:IllegalArgumentException:你好]命名的servlet和[com.crunchify.jsp.servlet.HelloCrunchify]都映射到
当我在服务器上运行的程序,我得到这个错误在控制台:
Caused by: java.lang.IllegalArgumentException: The servlets named [Hello] and [com.crunchify.jsp.servlet.HelloCrunchify] are both mapped to the url-pattern [/CrunchifyServlet] which is not permitted

我试图从服务器选项卡中删除服务器并再次增加。项目干净了吗?似乎没有什么能解决问题。
我的web.xml文件看起来是这样的:

我使用Tomcat 8和我的Java家被设定为 “javac 1.8.0_05
” 。 请帮忙!!!
这很奇怪,它说'/ CrunchifyServlet'被映射了两次,但我只能在web.xml中看到1! – Yazan
