Hi,
the @POST seems to be work, what I have done:
- set synchronous=true
- configure Jackson with FAIL_ON_EMPTY_BEANS
One thing that I can't solve it calling @POST method the payload not

code returns to client...

In case of calling @GET method the payload getting on the client...
I have shared the project :
https://gitlab.com/topicfun/cxfrs-put/tree/master
The important classes, resources are:
-
cxfrs-put/blob/master/tua-esb/src/main/java/hu/fornax/tua/esb/route/RestRouteBuilder.java
=> rest proxy
-
cxfrs-put/blob/master/tua-esb/src/main/webapp/WEB-INF/jboss-deployment-structure.xml
-
cxfrs-put/blob/master/tua-kodtar/src/main/java/hu/fornax/tua/kodtar/route/KodtarRoute.java
=> rest service
-
cxfrs-put/blob/master/tua-kodtar-protocol/src/main/java/hu/fornax/tua/kodtar/protocol/rest/KodtarREST.java
=> REST interface
and the full log calling @POST method:
