Hi Isuru, Thanks a lot for that pointer :) As you pointed out it seems the issue is related Accept content type of my request (application/rdf+xml).
I tried adding <messageFormatter contentType="application/rdf+xml" class="org.wso2.carbon.relay.ExpandingMessageFormatter"/> to the axis2.xml but still ESB serializes the BE response as a text/plain which results in just sending the HTTP 200 response header to the client. I also tried enabling <messageBuilder contentType="application/rdf+xml" class="org.wso2.carbon.relay.BinaryRelayBuilder"/> but still the in the out-sequence ESB tries to serialize the response as text/plain. Following is a full log of a sample request : curl -v -X POST -H "Accept: application/rdf+xml" -H "Content-type: text/plain" --data "sample request to detect cities like Paris in content." http://localhost:8280/services/StanbolProxy [2015-02-11 16:01:24,844] DEBUG - wire >> "POST /services/StanbolProxy HTTP/1.1[\r][\n]" [2015-02-11 16:01:24,846] DEBUG - wire >> "User-Agent: curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3[\r][\n]" [2015-02-11 16:01:24,846] DEBUG - wire >> "Host: localhost:8280[\r][\n]" [2015-02-11 16:01:24,846] DEBUG - wire >> "Accept: application/rdf+xml[\r][\n]" [2015-02-11 16:01:24,846] DEBUG - wire >> "Content-type: text/plain[\r][\n]" [2015-02-11 16:01:24,846] DEBUG - wire >> "Content-Length: 54[\r][\n]" [2015-02-11 16:01:24,846] DEBUG - wire >> "[\r][\n]" [2015-02-11 16:01:24,846] DEBUG - wire >> "sample request to detect cities like Paris in content."
