I'm unable to set the character encoding of the generated JSON output.

I tried

@Produces("application/json; charset=UTF-8")

but it doesn't seem to have effect (I tried "utf-8" as well). The output is always ISO 8859-1, which is the default encoding of my Java VM.

Looking into the code and debugging it some, I found out that the following method of JettisonMappedMarshaller gets invoked:

public void marshal(Object o, OutputStream outputStream)
throws JAXBException

{ marshal(o, new OutputStreamWriter(outputStream)); }

This one creates an OutputStreamWriter from an OutputStream. However, it doesn't set the encoding to be used in the writer, so it will be the default one (8859-1 in my case). I tried this with

marshal(o, new OutputStreamWriter(outputStream, "UTF-8"));

and then it generated proper UTF-8 at the end.

I don't know if this is the approriate solution, or how the actual output encoding should be set, but this seems probelmatic for me. Or if i'm doing something wrong I would be happy to get information how to set proper Resteasy/JAXB/JSON output encoding
