Sergey Beryozkin commented on CXF-5104:
---------------------------------------
thanks for a patch, I'll need to refresh my memory why I did it coded this way.
FYI, you can always use PhaseInterceptorChain.getCurrentMessage().
Also consider using JAX-RS 2.0 AsyncResponse
> JAX-RS not injecting contexts after resuming a suspended continuation

> Key: CXF-5104
> URL: https://issues.apache.org/jira/browse/CXF-5104
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Environment: CXF 2.7.5, MAC-OSX 10.7.5, Tomcat 7.0.41, Spring 3.0.7
> Reporter: Sharath P
> Labels: async, continuation, jax-rs

> Problem:
> In order to use continuations, I have a 'MessageContext' injected into the
> JAX-RS resource using @Context annotation. When the request is initially
> handled, JAX-RS properly sets the thread-local MessageContext
> (ThreadLocalMessageContext) for that particular instance of thread, and am
> able to retrieve the ContinuationProvider (in my case
> org.apache.cxf.transport.http.Servlet3ContinuationProvider) from context.
> Once I suspend the continuation and resume the same later, however, the
> thread-local MessageContext instance is not being set and therefore am unable
> to retrieve the resumed continuation (as ThreadLocalMessageContext is null
> through which continuation provider has to be retrieved).
> Possible Fix:
> Looks like the cause of the problem is in
> org.apache.cxf.jaxrs.JAXRSInvoker.invoke(Exchange, Object, Object)
> implementation, when a continuation is resumed, wasSuspended would be true
> and there is a conditional block which injects params and contexts only when
> wasSuspended = false. Extracting the injection of the params and contexts
> out of this conditional block would fix the issue as so:
> ******
> boolean wasSuspended = exchange.remove(REQUEST_WAS_SUSPENDED) != null;
>
> if (!wasSuspended) {
> pushOntoStack(ori, ClassHelper.getRealClass(resourceObject), inMessage);
>
> }
> final boolean contextsAvailable = cri.contextsAvailable();
> final boolean paramsAvailable = cri.paramsAvailable();
> if (contextsAvailable || paramsAvailable) {
> Object realResourceObject = ClassHelper.getRealObject(resourceObject);
> if (paramsAvailable) {
> JAXRSUtils.injectParameters(ori, realResourceObject, inMessage);
> }
> if (contextsAvailable) {
> InjectionUtils.injectContexts(realResourceObject, cri, inMessage);
> }
> }
> if (cri.isRoot()) {
> ProviderInfo<?> appProvider =
>
> (ProviderInfo<?>)exchange.getEndpoint().get(Application.class.getName());
> if (appProvider != null) {
> InjectionUtils.injectContexts(appProvider.getProvider(),
> appProvider,
> inMessage);
> }
> }
> ******
