Subject Re: Jetty Continuations in CXF

super.

I've just copied the relevant code only to sandbox as I didn't manage to create a branch :

https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations

Some comments. You can see in :

1. The wrapper interfaces for ContinuationSupport and Continuation in
https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/api/src/main/java/org/apache/cxf/continuations

2. How PhaseInterceptorChain deals with suspended exceptions in
https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/api/src/main/java/org/apache/cxf/phase/PhaseInterceptorChain.java

3. How AbstractInvoker deals with suspended exceptions in

https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/rt/core/src/main/java/org/apache/cxf/service/invoker/AbstractInvoker.java

4. How ChainInitiatorObserver deals with resuming an invocation chain in

https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/rt/core/src/main/java/org/apache/cxf/transport/ChainInitiationObserver.java

5. Jetty-specific continuation wrappers in

https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/rt/transports/http-jetty/src/main/java/org/apache/cxf/transport/http_jetty/continuations

6. How JettyDestination deals with continuations :

https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/rt/transports/http-jetty/src/main/java/org/apache/cxf/transport/http_jetty/JettyHTTPDestination.java

7. System tests :

https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/systests/src/test/java/org/apache/cxf/systest/jaxws/continuations

See the server code on how the test code interacts with continuations through wrappers :
https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/systests/src/test/java/org/apache/cxf/systest/jaxws/continuations/HelloImplWithWrapppedContinuation.java

and how it does so directly
https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/systests/src/test/java/org/apache/cxf/systest/jaxws/continuations/HelloImplWithContinuation.java

check
https://svn.apache.org/repos/asf/cxf/sandbox/2.2.x-continuations/systests/src/test/java/org/apache/cxf/systest/jaxws/continuations/jetty-engine.xml

on how a jetty engine on a specific port can be told to ignore continuations which are supported
by default if true is set or that 
attribute is omitted (not used in the test though)

Ok - you can now see it it so shoot :-) Comments are welcome

Sergey
