How to implement azure ad
OAuth Server JAX-RS endpoints. With CXF offering OAuth service implementations and a custom OAuthDataProvider provider in place, it is time to deploy the OAuth2 server. Most likely, you'd want to deploy AccessTokenService as an independent JAX-RS endpoint, for example: @PreMatching public class CorsFilter extends Object implements javax.ws.rs.container.ContainerRequestFilter, javax.ws.rs.container.ContainerResponseFilter Handles CORS requests both preflight and simple CORS requests. I am developing an example of a rest api using jax-rs and get to the point of having to add support for CORS and be able to consume it from an app made in React, the other day you publish the REST API on a server online and when the consumption in React of the way local works, but if I try to consume it from a page of type Stackblitz or resttesttest does not work.
