Sure, this is what JAXRSOutInterceptor does :
MessageContentsList objs = MessageContentsList.getContentsList(message);
if (objs == null || objs.size() == 0) {
return;
}
if (objs.get(0) != null) {
// this is what a given JAXRS method has returned : JAXRS Response,
Book, Feed, etc
Object responseObj = objs.get(0);
// convert to JAXRS Response if needed
Response response = null;
if (objs.get(0) instanceof Response) {
response = (Response)responseObj;
} else {
int status = getStatus(message, 200);
response = Response.status(status).entity(responseObj).build();
}
}
Next, JAXRSOutInterceptor will let filters, if any, react to this
Response, and override it if needed.
So if you'd like to check the response entity in the CXF interceptor
instead and say you know that your service does not return explicit
JAXRS responses then you can probably do :
MessageContentsList objs = MessageContentsList.getContentsList(message);
Object responseObj = objs.get(0)
// set etag on the Message.PROTOCOL_HEADERS
or just build a custom Response directly in this interceptor, using
JAXRS Response/ResponseBuilder api and set it on the message such that
JAXRSOutInterceptor can pick it up, you can do it like this :
Response response =
Response.ok().etag(etagValue).entity(responseObj).build();
outMessage.setContent(List.class, new MessageContentsList(response));
Hope it helps, Sergey

Cool - thanks
Is it possible to get hold of the JAXRS Response object in an impl of a
AbstractOutDatabindingInterceptor
In order to generate an etag from the response entity (not the http
response object, but the JAXRS Response) ?

Hi
Sorry about it, I fixed it, should be Message.PROTOCOL_HEADERS
Cheers, Sergey

Subject: Message.RESPONSE_HEADERS does not exist as documented in CCXF
2.2.5
Hi
In the documentation here is describes how to add a custom out
databinding interceptor to modify the response headers (eg to add an
ETag):
http://cwiki.apache.org/CXF20DOC/jax-rs.html#JAX-RS-Overridingresponsest
atuscodeandheaders
However the String Message.RESPONSE_HEADERS does not exist in the
org.apache.cxf.message.Message class in cxf 2.2.5
What should we be using instead to get the headers -
Message.PROTOCOL_HEADERS ?
Thanks
Paul
