Hey,
I have a use case where the user is requesting jsonp encoding e.g. via custom
media type or a .jsonw ending.
Anyway. I can intercept the call and surround with "jsonp();" successfully, but
the returned
content-type needs to be changed to "application/javascript".
I could accept that as incoming type, but then RE is complaining about no
matching MessageBodyWriter.
So I am thinking of using ContainerWriteFilter to re-write this, but the calls
seem to be
MessageHandler method (@GET foo() {} ) (1)
ContainerWriteFilter (2)
<message body writer> (3)
WriterInterceptor. (4)
(5)
So when I rewrite the content header in (2) a the mbw in (3) complains about
wrong type and
in (4) I can not check if the desired content type is my custom one to request
the wrapping or not.
So I would need to run a ContainerWriteFilter at (5) to rewrite the header
*after* the interceptor has run.
In RHQ I solved that with a normal servlet filter, but it looks like this does
not work here because
of Async processing (and rewriting the filter with an AsyncListener has its own
issues )
Thanks
Heiko
