/login/loginAction.action) is not available. 说你这个Action不可用！另外404错误时因为你的struts.xml的问题，好好看看你的配置文件

还是404,,,,,
http://localhost:8080/login/loginAction.action
http://localhost:8080/loginAction.action
http://localhost:8080/login.action
这些访问都一样404错误
程序是放在根目录,所以没有虚拟目录.
http://localhost:8080/login/loginAction.action
http://localhost:8080/loginAction.action
http://localhost:8080/login.action

没虚拟目录是不行的 建议加上虚拟目录在试
