I am trying to inject as a jax-rs mehtod param:
@Context CustomHttpRequest //implements HttpServletRequest
but following condition is true (for method param clazz=CustomHttpRequest) :
if (HttpServletRequest.class.isAssignableFrom(clazz)) {
value = m.get(AbstractHTTPDestination.HTTP_REQUEST);
}
thus same method fails on line:
return clazz.cast(value)
I would expect createServletResourceValue() will return null for clazz =
CustomHttpRequest .
> Cannot create ContextResolver for class extending HttpServletRequest,
> HttpServletResponse, etc.

> Key: CXF-6472
> URL: https://issues.apache.org/jira/browse/CXF-6472
> Project: CXF
> Issue Type: Bug
> Affects Versions: 3.0.4, 3.1.1
> Environment: all
> Reporter: tomek778
>
> I tried to wrap HttpServletRequest by using ContextProvider, lets assume such
> a simple implementation:
> @Provider
> public class CustomHttpRequestContextResolver implements
> ContextResolver<CustomHttpRequest> {
> @Context
> private HttpServletRequest request;
> public CustomHttpRequest getContext(Class<?> type) {
> return new CustomHttpRequest(request);
> }
> }
> However, before calling context provider CXF first calls
> JAXRSUtils.createServletResourceValue() method that tries to cast
> HttpServletRequest into my wrapped request and it fails with
> ClassCastException.
> I havent found in JAX_RS spec anything telling that such a ContextResolver is
> forbidden.This works also with Apache Wink.
