Sergey Beryozkin commented on CXF-6902: --------------------------------------- Hi, but JSONProvider can not handle Integer/etc, do you do some extra configuration of JSONProvider to make it happen ? Please debug your CXF 2.7 application: download CXF 2.7 source, put a breakpoint in JAXRSOutInterceptor, see which MessageBodyWriter gets selected Cheers, Sergey > Problem with resource that returns Object with CXF version == 3.1.2 > ------------------------------------------------------------------- > > Key: CXF-6902 > URL: https://issues.apache.org/jira/browse/CXF-6902 > Project: CXF > Issue Type: Bug > Components: JAXB Databinding > Affects Versions: 3.1.2 > Reporter: Balarami Reddy > > Hello, > We have recently migrated from 2.7 to 3.1.2 and we see a behaviour change in > CXF which blocked us from making progress. > The sample code below gives "No message body writer has been found for > response class Integer" which used to work perfect in CXF 2.7 > This is just sample code only. We have in our product several rest calls > which return integer/long/Object etc based on some calculations. > @GET > @Produces(MediaType.APPLICATION_JSON) > @Path("/getinteger") > public Response getInteger() { > return Response.ok(4).build(); > } -- This message was sent by Atlassian JIRA (v6.3.4#6332)
