Answer 1

struts.xml中
<package name="common" extends="struts-default">
换成
<package name="common" namespace="/common" extends="struts-default">
加个命名空间试试

Answer 2

还是不行，不过错误提示是
There is no Action mapped for namespace / 不是"/common",虽然我已经改了。

Answer 3

你的JSP页面form提交时中也要加:namespace="/common"

Answer 4

struts.xml中
<package name="common" extends="struts-default">
换成
<package name="common" namespace="/" extends="struts-default">

Answer 5

你看下我一个项目里的:struts.xml

参考下

Answer 6

我这边struts.xml里没有设置namespace, 右边的outline里自动有一个common的包，里面有login的action我的index.jsp如果用s:form就会又提醒unknown tag s:form，而且不支持namespace属性。

Answer 7

大哥，你是不是用的STRUTS2啊，如果是怎么不支持STRUTS标签了，还有你的index.jsp中根本没引用STRUTS2标签

Answer 8

用了struts2标签按你的改了后又404了

Answer 9

解决了，在爱问下的struts-spring-plugin是坏包，谢谢yulongde77同志了
