Presence data from web service

Question

Hello,
i like to get presence data from the presenceconsumer web service. But everytime a call getUserPresence i get a PolicyException (POL0002): 'Privacy verification failed for address %1, request is refused'.
I use a web service proxy generated from the wsdl of the presenceconsumer web service. Authentication is made against the appregationproxy by setting username and password. Both users (the one i use for authentication and the one whose presence data i want to get) are registered in the timesten database.
The user whose presence data should be accessed is logged in the OracleCommunicator and has the other user on the allowed list for presence data.
All other operations of the presence web services work without any problem, so why not getUserPresence?
Thanks for help

Hi,
I have found the problem and fixed it :)
If you see my code, I was checking for the pending subscriptions after publish() method. When I tried this check before publish() method, I got the expected results (All the pending subscriptions).
Also, I got an error (ServiceException) while dynamically retrieving the subscribed attributes for some reason. I have found an alternative solution, by manually allowing only the PresenceAttributeType.Activity (instead of all getSubscribedAttributes()).
Note: This code was working fine in my local machine because, I have already setup-ed the users (Buddy list) through Oracle communicator in my machine. I was not able to install OC in the VM for some reason though OS is same in both my machine and the VM (OS: Windows 2000 SP4).
thanks & regards,

My latest code for your reference.
