You don't need any extra bundles to serve static resources because Aries
JAX-RS whiteboard is built using Http Whiteboard which means that all you
need to serve your static resources is to place them in a bundle with the
following component:
@Component(
property= {
"osgi.http.whiteboard.resource.pattern=/static/*",
"osgi.http.whiteboard.resource.prefix=/path/in/bundle/to/static/resources"
},
service = Resources.class
)
public Resources {}
See
https://osgi.org/specification/osgi.cmpn/7.0.0/service.http.whiteboard.html#d0e121459
