Set HTTP Response in Interceptor

[HG-1 <hg...@proofpoint.com>]

I am using interceptor to check for existence of particular headers. If
headers are not there, then I want to the HTTP response to be a specific
HTTP resonse. But it seems that if I throw a fault, it always it always
returns 500 response. How can I send custom response codes in interceptor?

Here is my sample interceptor:

public class AuthCxfInterceptor extends AbstractPhaseInterceptor<Message> 
{
	
	public AuthCxfInterceptor() 
	{
        super(Phase.READ);
	}
	
	
	@Override
	public void handleMessage(Message message) throws Fault
	{
        HashMap pheaders = (HashMap) message.get(Message.PROTOCOL_HEADERS);        		
        
        Exception unauthException = new
WebApplicationException(Response.status(Status.UNAUTHORIZED).build());
        List<?> hdrValues = (List<?>) pheaders.get("myheaderkey");

        if (hdrValues.size() < 1)
        {
        	log.info("Missing myheaderkey");
            throw new Fault(unauthException);
        }
}

There is a Message.RESPONSE_CODE key that would be an integer for the for 
response code.  However, I think that needs to be set on the Fault message 
that would be created as part of the fault processing.   Thus, you MAY need to 
add an interceptor to the FaultOutChain to look for your fault and adjust the 
code.

Hi,

At the moment if you throw a Fault like this then it will escape the JAXRS runtime. I'll have to add JAXRS in/out fault interceptors 
to handle cases like this one which will check if the cause of a given Fault is a WebApplicationException.
The easiest way at the moment is to write a blocking CXF JAXRS RequestFilter and return a Response instance for the request to be 
blocked. This filter instance can be registered as a provider from Spring, please see [1] for more info

Cheers, Sergey
