Quarkus - Undertow
This document explains various Undertow features that you can use in Quarkus.
To serve static resources you must place them in the
META-INF/resources directory of your application. This is because
Quarkus applications are jar files rather than war files, and this location is the standard location for resources in
jar files as defined by the Servlet spec.
You can make use of the Undertow predicate language using an
undertow-handlers.conf file. This file should be placed
META-INF directory of your application jar. This file contains handlers defined using the
Undertow predicate language.
