<welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>dwr</servlet-name> <servlet-class> org.directwebremoting.servlet.DwrServlet </servlet-class> </servlet> <servlet-mapping> <servlet-name>dwr</servlet-name> <url-pattern>/dwr/*</url-pattern> </servlet-mapping> <filter> <filter-name>loginfile</filter-name> <filter-class>huawei.FileLogins</filter-class> </filter> <filter-mapping> <filter-name>loginfile</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
