thanks for your answer but now I'm totally confused...
If I set CamelCxfRsUsingHttpAPI to true the getKodtarElemListByType
works properly.
But in this case I got exception for
@POST
public Response createKodtarElem(KodtarDto dto);
08:49:11,874 SEVERE [org.apache.cxf.jaxrs.utils.JAXRSUtils] (default
task-10) No message body writer has been found for class
hu.fornax.tua.kodtar.dto.KodtarDto, ContentType: application/xml
08:49:11,875 WARNING [org.apache.cxf.phase.PhaseInterceptorChain]
(default task-10) Interceptor for
{http://localhost:8080/tua-kodtar/rest}WebClient has thrown exception,
unwinding now: org.apache.cxf.interceptor.Fault: No message body
writer has been found for class hu.fornax.tua.kodtar.dto.KodtarDto,
ContentType: application/xml
The json provider is set (&providers=#jsonProvider), I have tried with
JacksonJaxbJsonProvider and with JacksonJsonProvider as well
If I set CamelCxfRsUsingHttpAPI to false the @Post works. Otherwise
getting NPE to the @GET as I wrote in my first mail.
I want only to proxy rest request to an other service where a cxfrs
rest endpoint consume, please help me how I can solve it?
Thanks again your support!
