Where to put favicon to take JSF resource versioning into account?

In my JSF webApp I have put all of my resources (js, css, img) into a versioned library as pointed out by BalusC in this answer.

Now my favicon also resided here:

resources --> default --> 1_1 --> img --> favicon.ico

According to this answer the way to add the favicon would be: 

<link rel="shortcut icon" 
    type="image/x-icon" href="#{request.contextPath}/resources/default/1_1/img/favicon.ico"/>

But this way the resource handling that automatically picks files from the highest version folder (e.g. 1_1) is ignored and I would have to change this manually every time.

So is there another way to include the favicon or should the favicon be placed elsewhere (out of the versioned library)?

Solution

  • Use implicit EL #{resource} handler to let JSF convert a resource identifier to proper URL.

    <link ... href="#{resource['default:img/favicon.ico']}" />

    Note that this is also the way you're supposed to use to reference background images in CSS files.
