In my application,I use the struts2,and I create a base action to slove the path problem:
class BaseAction{
private String path;
static{
HttpServletRequest request = ServletActionContext.getRequest(); path=request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath();+"/";
}
}
Then all other action extend this baseaction.
In my jsp page,I add the path as the base:
xx.jsp:
....
<head>
<base href="<s:property value='path'/>">
<script ... src="res/test.js" />
</head&开发者_开发问答gt;
It works well in my own machine.
http://localhost:8080/app The test.js canbe found by "http://localhost:8080/app/res/test.js"
But when other people try to visit my app,they use:
http://192.168.x.x:8080/app.
now,the browser still try to download the test.js by "http://localhost:8080/app/res/test.js"
Of course,it can not get it. The real path should be: http://192.168.x.x:8080/app/res/test.js
SInce, the "path" is hard code in teh action,any idea to fix this?
In a static initialization block I wouldn't expect you to have a request available. I'd do:
<base href="${request.contextPath}" />
How about
<base href="${pageContext.request.contextPath}" />
You're setting the local host and port in the base path instead of the remote host and port.
This is after all not a nice construct to create the base path. I'd suggest to create it as follows instead:
path = request.getRequestURL().toString().replace(request.getRequestURI(), request.getContextPath()) + "/";
Or just nicely in JSTL/EL
<c:set var="r" value="${pageContext.request}" />
<base href="${fn:replace(r.requestURL, r.requestURI, r.contextPath)}/" />
