get response from spring oauth2 token request as xml -

i implementing oauth2 rest server using spring 4 , spring oauth2. response can either xml or json specifeid client request header. getting issues oauth2 when ever try access token supports json (application/json), not supporting xml(application/xml).

am getting error as:

http status 406 - type status report message description resource identified request capable of generating responses characteristics not acceptable according request "accept" headers. apache tomcat/7.0.54

my response json is:

i want xml

my mvc configuration follows:

please me..

marshallinghttpmessageconverter not smart enough convert access tokens. that's why spring oauth has jaxboauth2accesstokenmessageconverter (and jaxboauth2exceptionmessageconverter). need those, , need them in oauth2authenticationentrypoint , oauth2accessdeniedhandler used in /token endpoint security (assuming client wants security errors rendered in xml well). current @enableauthorizationserver support lets inject own authenticationentrypoint, you'll need extend authorizationserversecurityconfiguration override accessdeniedhandler.
