Hi,
When I am trying to run callback web service test (callback-basic-ws),
it works. What I have observed is that in this test case, both client &
server are in the same composite.
Then I tried to separate them out into 2 different composites. This gave
me the following exception at the server side:
Caused by: org.oasisopen.sca.ServiceRuntimeException: No callback wire
found

(( I tried to provide callback in my server composite also. ))
There is another application that I wrote myself which sort of
replicates the same scenario where in I found that I am getting a
NullPointerException when trying to access the @Callback annotated
variable in my serviceImpl.
This raised the following question in my mind. Is the Callback mechanism
fully supported on all bindings?
Or is it that there needs to be some extra information provided in my
server.composite file (which I don't think is the case), in case of
ws-binding? May be I am missing something somewhere!
