1 修改Tomcat的config/context.xml文件，把里面的<context>改成 <Context reloadable="true" privileged="true">.
2 去掉web.xml里面的两个注释如下：
<servlet> <servlet-name>invoker</servlet-name> <servlet-class> org.apache.catalina.servlets.InvokerServlet </servlet-class> ... </servlet> ... <servlet-mapping> <servlet-name>invoker</servlet-name> <url-pattern>/servlet/*</url-pattern> </servlet-mapping> 3 Go to install_dir/conf/web.xml, find the init-param entry for listings, and change the value from false to true.转载于:https://www.cnblogs.com/ocean010/archive/2009/05/25/1489104.html
