Description

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");
}
