Hi Joel,

Sometimes when i schedule a conference i get following error :

"Error 500: javax.ejb.EJBException: See nested exception; nested exception is: SchedConfException [result=UNRECOGNIZED_SERVER_ERROR]"


I can not predict this error as sometimes it works and sometimes it throws this error.
Needed your inputs on urgent basis.

Can you please let me know why this error occur and how to prevent it.

Looking forward for your earlier response..

Please find the Attached ScheduleConferene COde
Thanks and Regards,

Swapnil.

I guess, Correct me if i am wrong ,This is because Scopia server fail to respond sometimes to request.

I would also like to know which method of SchedConf Interface will give me Conference GID
1)getConfID
2)getNumberAsString
3)getDialIn

This error is sporadic.

Requires your input on urgent basis.
How should i prevent such sporadic behavior?
Sometimes it works fluently and sometime it throws this error.



I also want to know which method of SchedConf Interface will give me Conference GID :

getConfId()
getNumberAsAString()
getNumber()
getDialIn()

I tried each of this method and still Invite_Participant_Request Gives me same response i.e ConferenceNotFound

See Invite_Participant_Response returned by Scopia :

Scopia Response Invite Participants : <?xml version="1.0" encoding="UTF-8"?><MCU_XML_API><Version>8.0</Version><Response><Invite_Participant_Response><RequestID> 12345 </RequestID><ConfGID>2653</ConfGID><Invite_Part_List><Invite_Part><PID></PID><DialStr>2304</DialStr><ReturnValue>ConferenceNotFound</ReturnValue></Invite_Part><Invite_Part><PID></PID><DialStr>2300</DialStr><ReturnValue>ConferenceNotFound</ReturnValue></Invite_Part><Invite_Part><PID></PID><DialStr>2301</DialStr><ReturnValue>ConferenceNotFound</ReturnValue></Invite_Part></Invite_Part_List><ReturnValue>OK</ReturnValue></Invite_Participant_Response></Response></MCU_XML_API>




Please reply back as soon as possible.
Looking forward for your earlier response
