$http.get is not allowed by Access-Control-Allow-Origin but $.ajax is

Question

I have a problem fetching json from a remote server that I control. I have 2 web applications, one serving data and running on port 3311, the other, requesting data, is run

Answer 1

Requested headers has to be set at the server side. There are many ways in setting this

1.One can be

 
   ResponseFilter
   org.apache.catalina.filters.CorsFilter
 
 
   ResponseFilter
   /*
 

2.Independent of the server you can develop a custom class that can be passed as init paramter to jersey servlet com.sun.jersey.spi.container.ContainerResponseFilters helpers.TestCorpsFilter enter code here `public class TestCorpsFilter implements ContainerResponseFilter {

    @Override
    public ContainerResponse filter(ContainerRequest arg0, ContainerResponse arg1) {
        ResponseBuilder resp = Response.fromResponse(arg1.getResponse());
        resp.header("Access-Control-Allow-Origin", "*").header("Access-Control-Allow-Methods",
                "GET, POST, OPTIONS");

        String requestHeader = arg0.getHeaderValue("Access-Control-Request-Headers");

        if (requestHeader != null && !requestHeader.equals("")) {
            resp.header("Access-Control-Allow-Headers", requestHeader);
        }

        arg1.setResponse(resp.build());
        return arg1;

    }
