    I just had the same problem with JSF 2.0. I had to use a CSS and the solution with the relative path didn't work for me either (like Choghere posted).

    In my book I read that when you use Facelets as VDL (View Declaration Language) it is possible to use expressions even in a plain HTML page. So I got the idea to put a EL directly in my CSS. Note: I didn't have to change the filename or anything.

    Here is what I did. but first my filestructure:

    • /resources/common/overlay.xhtml -> this one icludes the following css (its a composite component)
    • /resources/common/overlay.css
    • /resources/images/logo.png

    Now here comes the CSS:

    .someclass { 
        background-image:url("#{resource['images:logo.png']}"); 
    }
    

    in this case resource is an implicit object of JSF 2, images is the library where JSF should look (jsf expects all libraries/files under resources, at least the default ResourceHandler) and then the name of the resource.

    For deeper structures it would be:

    #{resource['images/folder:logo.png']}
    

    Hope that helps ;)
