Set Access-Control-Allow-Origin in Raml API

[elhamroshan]

I'm trying to set Access-Control-Allow-Origin in my Raml API. Found in the web that I can do that by adding headers to my responses like:

    responses:
      200:
        headers:
          Access-Control-Allow-Origin:
            example: |
              *
          Access-Control-Allow-Methods:
            example: |
              GET, POST
          Access-Control-Allow-Headers:
            example: |
              Content-Type

I've done this but it fails compiling the code with the following error:

 method respond200WithApplicationJson in class GetApiV1ProjectsResponse cannot be applied to given types;
[ERROR]   required: ApiV1Projects.GetApiV1ProjectsResponse.HeadersFor200
[ERROR]   found: java.lang.String
[ERROR]   reason: actual and formal argument lists differ in length

Current java code when returning the response:

return GetApiV1ProjectsResponse.respond200WithApplicationJson(projectsToJson(restResponse));

Should I add any changes to my response implementation? What is missing here?

Thanks in advance!

I've been busy elsewhere, sorry for the delay. I'll check this tomorrow morning. Promise.

There is an example in the project of using headers: raml-to-jaxrs/examples/maven-examples/raml-defined-example/src/main/java/server/humanity/HumanityImpl.java

But if you could give me a mode complete example maybe I could see what is wrong ?
