What is the recommended way to configure mime types?

[DaanVanYperen]

When I run this example project with embedded tomcat and project-stage: Development I get the following error for all resources:

 JSF1091: No mime type could be found for file /index.xhtml.  To resolve this, add a mime-type mapping to the applications web.xml.

I can work around it using a WebServerFactoryCustomizer. MimeMappings.DEFAULT provides no mime types so i'm not sure if that is the recommended way to solve it in joinfaces.

@Component
public class MimeMappingCustomizer implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> {

    @Override
    public void customize(TomcatServletWebServerFactory factory) {
        MimeMappings mappings = new MimeMappings(MimeMappings.DEFAULT);
        mappings.add("xhtml", "application/xhtml+xml");
        factory.setMimeMappings(mappings);
    }
}
