json - How to override response header in jersey client

Question

I have a jersey client that I am trying to unmarshall a response entity with. The problem is the remote web service sends back application/octet-stream as the content type so Jersey does not know how to unmarshall it (I have similar errors with text/html coming back for XML and such). I cannot change the web service.

What I want to do is override the content-type and change it to application/json so jersey will know which marshaller to use.

I cannot register application/octet-stream with the json marshaller as for a given content type I actually might be getting back all kinds of oddities.

As laz pointed out, ClientFilter is the way to go:

client.addFilter(new ClientFilter() {
    @Override
    public ClientResponse handle(ClientRequest request) throws ClientHandlerException {
        request.getHeaders().putSingle(HttpHeaders.CONTENT_TYPE, "application/json");
        return getNext().handle(request);
    }
});
