REST WebClient: how to inspect and set eTag headers?

Hi,

I want to inspect eTag headers in responses from a REST service, to set them on later PUT requests. Any guidelines on how to do this with the CXF WebClient API? 

Thanks
Guy

You can do something like this:

Book book = webClient.get(Book.class);
Object header = webClient.getResponse().getMetadata().getFirst("ETag");
if (header != null) {
    EntityTag eTag = EntityTag.fromString(header);
    ...
}

In JAX-RS 2.0 it will be easier to deal with Response headers.

and then

webClient.header("If-None-Match", eTag);
etc...

Cheers, Sergey
