    Allowing Cross-Origin Requests

    Royi Bernthal Newbie

      I'm trying to make Wildfly allow Cross-Origin requests, in order to be able to send requests to localhost using local JavaScript code.


      Here's a request I'm making via JavaScript:


      var request = new XMLHttpRequest();
      request.open("GET", requestUrl);
      request.setRequestHeader("Access-Control-Allow-Origin", "*");



      An error is thrown in the dev console when testing in Chrome.

      XMLHttpRequest cannot load http://localhost:8080/.... Request header field Access-Control-Allow-Origin is not allowed by Access-Control-Allow-Headers in preflight response.

      The request fails on Firefox as well, although no error is thrown in this case.



      I modified my standalone.xml and restarted Wildfly according to this answer, to no avail:

      jboss - CORS: AngularJS + Resteasy 3 + Wildfly - Stack Overflow


      I even tried creating a filter class according to this answer, it didn't help as well:

      jax rs - How to enable Cross domain requests on JAX-RS web services? - Stack Overflow

      I didn't change any configurations to include this class however, in case such a thing is required for it to work.
