I've tested two remote methods :

@GET
@Path("/getprofile/

{id}")
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
ClientProfile getClientProfile(@PathParam("id") Integer id);

@GET
@Path("/getprofile2/{id}

")
@Produces(

{MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML}

)
List<ClientProfile> getClientProfile2(@PathParam("id") Integer id);

The second one only wraps result of the first. The content type of resposne is "application/json;charset=utf-8". After unmarshalling in client the first one gives me utf-8 encoding issues in text properties while the second one gives me correct result. It looks like JAXBXmlRootElementProvider doesn't use proper charset in the first example while, ran in JsonCollectionProvider - works fine. In debugger MediaType looks to be passed the same way both times.

If I change JSON to XML marshalling like this : @Produces(

{MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON}

) both methods work fine.
