While including css, js and images in my jsps I am facing a problem resolving relative urls. The urls get changed on refreshing the page or clicking the back button. I suppose one solution to the problem would be to include external files by using absolute urls. But I can't find out how to use a reference to the relative url and use it. Can anyone please help me on this?

This would also work and may be easier to read and has some extra benefits such as proper escaping and optional inclusion of parameters

<link href="<c:url value="/style/style.css"/>" rel="stylesheet" type="text/css" />

Is this what you're looking for?

${pageContext.servletContext.contextPath}

and then in your jsp:

<link rel="stylesheet" href="${pageContext.servletContext.contextPath}/css/page.css"   media="all"    type="text/css" />

Answered this old question because absolute URLs can be useful for javascript using a reverse proxy. The same could work for href too. However in our case the reverse proxy takes care of href urls and so a relative path works just fine.

To get an absolute url for the original question try this:

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<link rel="stylesheet" href="${fn:replace(pageContext.request.requestURL, pageContext.request.requestURI, pageContext.servletContext.contextPath)}/style/style.css" rel="stylesheet" type="text/css" />

The replace function takes the requestURL i.e.: http:/mydomain.com/context-path/index.html

And replaces the requestURI: /context-path/index.html

With just the context path: /context-path

Resulting in: http:/mydomain.com/context-path

Then append the desired resource: /style/style.css
