Load Presence Status of a user in Spark without adding in Roster

Hello Guyz

I am new to Openfire and Spark. Hope i ll get help .

I installed both server and client successfully and connected to Active Directory.

I also installed Presence Service plugin in Openfire server .

My requirement is : When a user searches for another user in Spark client and clicks on the user for a chat ,he should get a Presence status of that user without adding him in Roster. 

I am getting user presence status via URL such as : http://cdcccommunicator:9090/plugins/presence/status?jid=00504804@cdcccommunicat or

But not via Spark client .

How can i achieve this ??
