Dan,
Thanks for the reply. I think the problem was on my end, (see other post
I just made in this thread to Dan), but I'm not entirely sure if what
was mentioned was a symptom, or the problem itself.
Cheers,
Brad

I published new CXF snapshots Saturday morning. If you're using the
snapshots, that could have done it.

The plot thickens. I changed the code back, so that Collection was no
longer there, and the orginal ArrayList is there. The code is *still*
crashing however. My input has not changed -- it is hard-coded, so I
know for a fact it has not changed. I am now suspecting some new
resource that may have been posted to an online maven repository,
because that's the only thing I can think of that could have injected
new code into my code-base, as I am building with maven. Is anyone
aware of any new CXF artifact or dependency that has hit public maven
repositories within the last day?
Thanks,
Brad

I have a RESTful service configured with Spring. Here is the
interface:
@WebService
public interface IUserService {
@Post
@HttpResource(location="/authenticate")
AuthenticateResponse authenticate(AuthenticateRequest request)
throws KilterException;
@Post
@HttpResource(location="/getEntities")
ArrayList<User> getUsers(GetUsersRequest request) throws
KilterException;
}
This service works without error. However, I made one change, which
was changing the return type of the getUsers method from the
ArrayList listed to a Collection, as follows:
@Post
@HttpResource(location="/getEntities")
Collection<User> getUsers(GetUsersRequest request) throws
KilterException;
This was the ONLY change made. Though my server loaded the service
without error, oddly, invoking the authenticate method, in the same
way as before, with the same exact data, resulted in the following
exception (NOTE: the code of my actual service was never invoked,
this exception occurred in the CXF API which was processing
parameters). So apparently, this Collection type, though on the
getUsers method, prevented the authenticate method from being
invoked. ??? Does anyone have any idea why this would be, and how to
rectify it? The exception is below:
