How to Use Font Awesome Icons from Webjars.org in JSF?

Using Font Awesome from Webjars.org in JSF

You've encountered an issue while trying to use Font Awesome icons in a JSF application. Initially, accessing the icon resources from Bootstrap's servers worked, but when trying to bundle them within your WAR, the font files couldn't be located.

The problem lies in the file references within the CSS resource file. The URLs generated by JSF expected the "webjars" library and a resource extension (.xhtml in your case) to be included, which were missing from the original paths.

Solution:

1. Introduce OmniFaces UnmappedResourceHandler: Install and register OmniFaces in your application to handle resources that wouldn't otherwise be mapped by JSF.
2. Modify FacesServlet Mapping: Add "/javax.faces.resource/*" to the FacesServlet mapping to allow processing of unmapped resources.
3. Update Library Name: Move the "webjars" library name from the into the resource name.

With these modifications, your application should now correctly resolve and display the Font Awesome icons from the bundled JAR.
