Hi All,
I'm resuming this thread that was started at the JSR-339 list (more
comments to the original email can be checked at that list).
I've just seen another CXF issue opened specifically to do with this issue.
The client does:
GET /a
Accept: text/*
The server has
@Produces(text/*)
@GET @Path("/a")
The spec requires 406 in this case and this just appears to be wrong.
Neither a client nor a server have made a mistake: the client is stating
it can take any text variations, the server is expecting the client to
specify a concrete Accept - in fact some other clients may do just that.
Any ideas how it can be improved ?
Given a final text/*, what can server actually return ?
CXF does application/octet-stream. The client can at least react to the
possible deserialization issue locally or it may even work if String is
expected for example.
Should we at least provide the defaults for some well known types, IMHO
this might be a reasonable compromise.
For example, the spec defaults application/* to
application/octet-stream. Similarly text/* can be to text/plain. Do the
same for few more well known types ?
Thanks, Sergey
