Actually, I've just reread your email...
Injecting HttpHeaders into your abstract class is what I'd still recommend, but just pulling up a variable annotated with
@HeaderParam should still work though I may need to add a test to verify it works with the abstract classes.
The problem is that an injection into fileds annotated with @HeaderParam is not thread-safe for singleton resources (as opposed to
say @Context HttpHeaders headers;). If you do prefer to inject an individual @HeaderParam value as opposed to HttpHeaders then the
the safest option here is to use a constructor injection of a given header parameter and make sure the resource has the prototype
scope...

Hi
this should work, there's a couple of options, assuming you have an abstract
class which all other resource classes extend
1. just have a private field :
@Context
private HttpHeaders headers;
2. Alternatively, have a setter :
// note, no @Context
private HttpHeaders headers;
public void setHttpHeaders(HttpHeaders headers) {this.headers = headers;}
this 2nd option may work better if you have Spring proxifying your resource classes; for ex, you could have a dedicated interface
like Injectable (the name of the interface is up to a user to choose) which this abstract class will implement and thus will help
Spring to inject if Spring proxies are pure JDK proxies as opposed to CGLIB ones...
cheers, Sergey

Subject: How to have a super class of the resource class use CXF annotations?
That subject isn't worded quite right, but hopefully I can clear that
up.
I started out with a small handful of resource classes, each of which
points to a separate portion of my domain classes. I realized that
there are some HTTP headers that I'd like to get automatically, without
specifying them explicitly in each method. I realized I could just
define an instance variable in the resource class and then put the
"@HeaderParam annotation on the field. That works fine. However, what
I'd really like to do is have a base class that all the resource classes
extend, which has the annotated instance variable. All I did was "pull
up" the instance variable and the getter/setter to a base class and
retested that, and I found that the instance variable was not set.
Is there something I have to do to get CXF to look at the base class for
CXF annotations, or is this a scenario that isn't possible yet?
