tomcat xml配置

如果在tomcat的web.xml配置中
 <servlet>
    <servlet-name>delBatchCheck</servlet-name>
    <servlet-class>servlet.delBatchCheck</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>delBatchCheck</servlet-name>
    <url-pattern>/delBatchCheck</url-pattern>
  </servlet-mapping>
如果上述中的<url-pattern>/delBatchCheck</url-pattern>写成<url-pattern>delBatchCheck</url-pattern>会出现Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext错误
无法进行虚拟目录
