CORS: AngularJS + Resteasy 3 + Wildfly

I am developing an application using AngularJS and Resteasy. As expected, I ran into a known issue

XMLHttpRequest cannot load http://localhost:8080/..... No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 403.

As you can see from other posts [1] , I tried using the Restaasy CorsFilter from the Feature object, but I get:

[33m02:06:57,883 WARN  [org.jboss.resteasy.core.ExceptionHandler] (default task-1) failed to execute: javax.ws.rs.ForbiddenException: Origin not allowed: http://localhost:3000
    at org.jboss.resteasy.plugins.interceptors.CorsFilter.checkOrigin(CorsFilter.java:194)
    at org.jboss.resteasy.plugins.interceptors.CorsFilter.filter(CorsFilter.java:134)

      

        
        
        
      

    

My CorsFeature object :

@Provider
public class CorsFeature implements Feature {

    @Override
    public boolean configure(FeatureContext context) {
        CorsFilter corsFilter = new CorsFilter();
        corsFilter.getAllowedOrigins().add("*");
        context.register(corsFilter);
        return true;
    }  
}

      

        
        
        
      

    

In web.xml, I added:

<context-param>
    <param-name>resteasy.providers</param-name>
    <param-value>org.jboss.resteasy.plugins.interceptors.CorsFilter</param-value>
</context-param>

      

        
        
        
      

    

I see that when I comment out this context parameter, I do not get the above exception and the response status is 200, not 403.

In angular config I added:

$httpProvider.defaults.useXDomain = true;
delete $httpProvider.defaults.headers.common['X-Requested-With'];

      

        
        
        
      

    

I know it is possible to create a node.js proxy, but I would like to tackle this the hard way. Can you please help me overcome this big obstacle in life?

Thank:)

Edit later: I was able to do this by annotating the (CorsFeature) si @Component feature class. So the application context is aware of this.
