Content-Type problem

[Lange Gunter (ID SWS)]

Hi

Can anybody help me?

We are using apache-cxf-3.3.1.

I want to intercept JSON Mapping Errors. It goes well but the response’s 
Content-Type is always XML.

My provider method is:

public class JsonMappingExceptionMapper implements 
ExceptionMapper<JsonMappingException> {

    private final HashMap<String, ResponsePayload> payloads =
            
Messages.INSTANCE.getResponsePayloads(this.getClass().getSimpleName());

    @Override
    public Response toResponse(JsonMappingException ex) {

        ResponsePayload payload = 
payloads.get("mapping_error").format(ex.getMessage());
        return 
Response.status(Response.Status.BAD_REQUEST).entity(payload).build();
    }
}


The Restful Web Service is called with Header Parameter: -H 
"Content-Type:application/json;charset=UTF-8" -H "Accept:application/json"

As I see in ExceptionUtils.java (line 99)  : 
JAXRSUtils.setMessageContentType(currentMessage, response) the currentMessage 
contains "Content-Type" -> "application/json;charset=UTF-8"

But then in setMessageContentType()

        if (response != null) {
            Object ct = 
response.getMetadata().getFirst(HttpHeaders.CONTENT_TYPE);

this information about the currentMessage.Content-Type is not taken into 
account.

How I'm able to reply with a JSON Response?

Thanks in advanced.

Best regards
Gunter
