Hi,
I've been working on supporting multiple charsets in my
MessageBodyWriter.
If I understand correctly then this requires:
1. Request Header 'Accept' would contain the charset, for example
'text/plain;charset=UTF-8'
2. The MessageBodyWriter would check that it can indeed produce this
charset in #isWriteable() based on the MediaType instance
3. The MessageBodyWriteer would properly encode the output in
#writeTo(), again based on the MediaType instance
For a request with 'Accept: text/plain;charset=UTF-8' I indeed get the
charset in #isWriteable().
But in #writeTo() the media type is always "text/plain".
I stepped through the code, and it seems that jersey's
MessageBodyFactory#getMessageBodyWriterMediaType() finds that the most
specific media type given the MBW @Produces("text/plain") and the
acceptable media type of "text/plain;charset=UTF-8" is "text/plain", and
gives this to the #writeTo() method.
Is my approach of detecting the charset wrong, or is this a (known?)
bug?
This is with jersey 1.1.1-ea (historic reasons), but it seems the code
in the latest 1.11 is very similar.
Regards,
Andreas
PS: Does jersey merge the information from the Accept-Charset request
header into the acceptable media type?
