Question

请教下各位兄弟们
HTTP Status 503 - Servlet dispatcher is currently unavailable
这个是什么问题？
我都查了好久了
先谢了：）

Answer 1

当前servlet转发器不可用，检查一下web.xml是不是写错了？

Answer 2

你用的struts几呀，控制器不可用，和楼上的大哥哥说的一样。

Answer 3

struts1.2.9
web.xml 内容如下:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
