Thank you for your help
> jax-rs2 request filter is unable to modify request header by adding a new
> header
> ---------------------------------------------------------------------------------
>
> Key: CXF-4986
> URL: https://issues.apache.org/jira/browse/CXF-4986
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 2.7.2
> Environment: cxf on tomcat
> Reporter: abdelgadiri
> Assignee: Sergey Beryozkin
> Fix For: 2.8.0, 2.7.5
>
>
> I have a filter implementation as follows
> @Provider
> public class AuthSessionFilter implements ContainerRequestFilter {
> public AuthSessionFilter() {
> }
> @Override
> public void filter(ContainerRequestContext requestContext) throws
> IOException {
> //another @Prematching filter is setting this session id so it is
> definitely not null
> Object sessionId = requestContext.getProperty("sessionId");
> if (sessionId == null || GeneralUtils.isNullOrBlank(sessionId + "")) {
>
> requestContext.abortWith(Response.status(Response.Status.UNAUTHORIZED)
> .entity("missing sessionId").build());
> }
> //this line gets invoked without problems, however, the added header
> is not available from the resource class
> requestContext.getHeaders().putSingle("sessionId", sessionId+"");
> }
> }
> The line requestContext.getHeaders().putSingle("sessionId", sessionId+""); is
> not making the added sessionId header available when trying to obtain it from
> my resource. getHeaders() is supposed to return a mutable map in accordance
> with the spec, but its implementation 'ContainerRequestContextImpl' is
> returning a readonly map instead. it returning:
> return new MetadataMap<String, String>(
> (Map<String, List<String>>)m.get(Message.PROTOCOL_HEADERS),
> false, true, true);
> where it is passing 'true' for the readonly parameter.
> in my resource, I am trying to obtain the header using
> public Response doSomething(UriInfo uriInfo, HttpServletRequest request) {
> //this is always null even though it shouldn't be null
> String sessionId = request.getHeader("sessionId");
> }
