Hi Jean,
Indeed the way you would like to do that is somewhat tricky.

This is one of the possible options but OpenAPI/Swagger gets confused for a
reason: the path is now implicit (not in the spec).
So how about this option:
- use only one JAX-RS server (address "/")
- host both resources but use @Path("accounts") and @Path("resources") on them
respectively
I see that for @Path("accounts") you need to apply the
"kmopApiAuthorizationFilter", that could be done using
DynamicFeature [1], [2]. If this is not the option and you would prefer to use
2 separate JAX-RS servers, you
may need to provide your own instance of Swagger2Customizer [3], [4] which
allows to transform the OpenAPI/Swagger
on the fly. Please let me know if that would it work for you, thank you.
