    Errai and RestClientInterceptor

    Mark Badorrek Newbie

      Dear all,


      I've implemented a RestClientInteceptor and all is well for the request side of things.

      However, I'm having some problems with the response side.


      I have a line in the code:   context.proceed(callback);

      The problem is that I have no idea how to access the Response Headers from my callback. The callback gets called and everything is OK - I just can't seem to find out how to access the info I need.

      Any examples of a callback accessing response headers would be great.


      Any help is most appreciated.

          Hi Mark,


          Using either 2.4.4-SNAPSHOT or 3.0-SNAPSHOT you should be able to pass a ResponseCallback to your context.proceed call even if your actual remote callback is a standard RemoteCallback. The ResponseCallback provides access to the Response object and its headers.


            public void aroundInvoke(final RestCallContext context) {
              context.proceed(new ResponseCallback() {
                  public void callback(Response response) {
                   // access headers using response.getHeaders()..


          Don't forget to set the result using context.setResult.

            Hi Christian,


            Sounds like that's exactly what I need.

            I'd like to move up to either of the two snapshots that you've provided, but I always seem to have a lot of difficulty amending my pom.xml to make the jump to the new version. There always seems to be something that doesn't work and prevents me from continuing.

            Here's my existing pom (attached) - what should I change to move to either 2.4.4 snapshot or 3.0-snapshot?

            Many thanks,
