Rao,
Thanks for replay,
Getting this exception while POST the request - "org.springframework.http.converter.HttpMessageNotReadableException: Could not unmarshal to[class com.server.domain.Participant]: null; nested exception is javax.xml.bind.UnmarshalException - with linked exception: [org.xml.sax.SAXParseException: Premature end of file.]"
I've included Authentication header with preemptive type and i'm sure that no other headers are needed for this request.
Able to POST the request successfully without any issues using RestClient firefox plugin.
Thanks,
Hari
