Use Java webapp context for web-html issues
Hypothesis:
We have a wonderful java web application which is reachable from:
And you have to setup css and js scripts, something like
<link href="path/sitestyle.css" media="screen" type="text/css" />
and
<script type="text/javascript" src="path/mootools.js"><script>
But the problem is: how to write the correct path using an absolute path? (relative path sucks).
Why absolute path: I really love absolute path because when using struts with actions you can really go crazy.
So in your JSPs using the standard JSTL
<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c" %>
try to use this:
<c:set var="currentPath">http://<%= request.getServerName()+":"+request.getServerPort()+request.getContextPath() %></c:set>
so this variable "currentPath" will be rendered as http://internet.externalhost.com:80/myapp if users are coming from internet, rendered as http://intranethostname/myapp if visiting from lan.
The html maybe should be:
<%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c" %>
<c:set var="currentPath">http://<%= request.getServerName()+":"+request.getServerPort()+request.getContextPath() %></c:set>
<html>
<head>
<link href="<c:out value="${currentPath}" />/css/sitestyle.css" media="screen" type="text/css" />
<script type="text/javascript" src="<c:out value="${currentPath}" />/js/mootools.js"><script>
</head>
<body>
[ ... ]
</body>
</html>
