Currently i am using ejabberd 14.05 server and using it`s mod_rest module to update the presence of the user from server based on a certain condition from a 3rd party web service. But i am not able to post the presence stanza to update the presence of user. Below are my finding.
command using to invoke the presence stanza via mod_rest. curl --verbose --data "World" -X POST servername:5280/rest/ -H "Content-Type: text/xml" -H "Accept: application/xml"
logs.

Its somehow not able to parse the stanza. Not sure why this is happening :( Any pointers in this direction are useful. Please also let me know there is any another approach to do this would be also helpful.
EDIT 1: There was some issue with the CURL. So i switched to POSTMan Client in chrome.Now the stanza are atleast getting parsed. Now the issue is that the message stanza is working for me but the Presence stanza is not working for me. I am now able to establish the client to server session.Can any one please help me with it.
