In JSF applications, it's possible to leverage Font Awesome icons by incorporating the appropriate resources into a view's
If you intend to use the prepackaged JAR from webjars.org for Font Awesome and configure your views to employ bundled resources, you may encounter challenges when referencing font files. To resolve this issue, ensure the correct JSF mapping and library name are included in the URLs.
In cases where external resources are not under your control and present challenges, OmniFaces offers a solution: the UnmappedResourceHandler. This utility library allows for the efficient management of resource handling.
Steps to Resolve the Issue Using OmniFaces:
<dependency> <groupId>org.omnifaces</groupId> <artifactId>omnifaces</artifactId> <!-- Check omnifaces.org for latest version --> <version></version> </dependency>
<application> <resource-handler>org.omnifaces.resourcehandler.UnmappedResourceHandler</resource-handler> </application>
Assuming the servlet name is "facesServlet" and it has a mapping on .xhtml, add the following mapping for /javax.faces.resource/:
<servlet-mapping> <servlet-name>facesServlet</servlet-name> <url-pattern>/javax.faces.resource/*</url-pattern> <url-pattern>*.xhtml</url-pattern> </servlet-mapping>
In
<h:outputStylesheet name="webjars/font-awesome/3.2.1/css/font-awesome.css" />
After completing these steps, JSF's resource handling mechanism should correctly locate the necessary font files, and your Font Awesome icons will be rendered as expected.
