I Got following error while using conference for second time.
Now i am getting same error each time.

"Error 500: java.lang.IllegalStateException: State of SchedObject instance does not allow this operation (this operation must be performed before a conference is scheduled). "

I am stucked here from last five days. :cry:

Can you please give me pseudo code to Scheduling conference between three participants
This help will be really appreciated.

Thank you..

It looks to me like you're attempting to reuse the same SchedConf object for multiple conference calls. You need to create a new object for each conference call.

Yes. I am creating new Conference object every time.
I have written servlet to call the method.
Each time when i call the same service second time i gives exception.
After that i need to uninstall and delete the service or need to upload new version of services.

Basically, particular version service can only be use only one time. It won't work for second time.

So here's the thing that made me say you're using as single instance of SchedConf. In MaintenanceConferenceImpl, you've got this line:

final static SchedConf conference = SchedConfFactory.createConf();

I'd have thought that conference would be a local variable in your makeConference method. A static variable is global. It appears that it is initialized only once at startup.

Am I missing something here?

Hi Joel,

Yes you are right.
It is a static variable so it was causing problem.


Thank you.

I'm happy to hear that you got the problem resolved!

Hi Joel,

Now i am getting following error.

Can you please let me know the reason of this error and resolution to this error
