css 文件加载不进的问题。
web application 跟目录：
war -|login.jsp
|common/css/pageStyle.css

login.jsp & common locate at the root directory.

in login.jsp , I coded like this :

<link href = "common/css/pageStyle.css " rel = "stylesheet " type = "text/css " />
or this :
<link href = "../common/css/pageStyle.css " rel = "stylesheet " type = "text/css " />

it doesn 't work either .

why ?

The CSS File just define the style of the body tag:
body {
background-color : #FEFEFE
}


------解决方案--------------------
<link href = "./common/css/pageStyle.css " rel = "stylesheet " type = "text/css " />
