Setting outbound HTTP header from JAX-WS handler does not work

[jbonham100]

Hello

I'm trying to set an outbound HTTP header in a JAX-WS handler with no success.

Here's the code snippet:

private static final String PERFORMANCE_HTTP_HEADER = "X-Perf";

private void logPerformance(SOAPMessageContext smc) {

                   ...

                    @SuppressWarnings("unchecked")
                    Map<String,List<String>> headers = (Map<String,List<String>>) smc.get(MessageContext.HTTP_RESPONSE_HEADERS);
                    if (null == headers) {
                        headers = new HashMap<String,List<String>>();
                    }
                    headers.put(PERFORMANCE_HTTP_HEADER, Collections.singletonList(msg));
                    smc.put(MessageContext.HTTP_RESPONSE_HEADERS, headers);

The header doesn't show up in the response.

Any ideas would be greatly appreciated.

Thanks

Andre
