Hi Uvindra,
Seems message failing during the building. And it picks the wrong formatter
it seems. Set the content header in the curl as follows.
curl -i -POST -H 'Accept: application/json' -H
'Content-Type:application/json' -d '{"celsius":12}' http://<IP
Address>:8280/<api context>
Thanks,
Asanka D
