Hi,

I cannot be able to execute a call to my BackEnd service (RestEasy) through Chrome because the response is:

"esponse to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access."

I inserted a custom RESTEasyContextMapper with override to mapTo using:

context.setProperty("Access-Control-Allow-Origin", "*").addLabels(new String[]{ EndpointLabel.HTTP.label() });

....

httpHeaders.put("Access-Control-Allow-Origin", Arrays.asList("*"));

httpHeaders.put("Access-Control-Allow-Headers", Arrays.asList("Access-Control-Allow-Origin,origin,name,Content-Type,accept"));

httpHeaders.put("Content-Type", Arrays.asList("application/json,text/plain,*"));

But it doesn't work.

Can you help me please?
