How to schedule a long time operation in Zimbra 8
I have to update an Zimbra 6 extension (server side) which was developed few years ago to Zimbra 8. This extension uses com.zimbra.cs.operation.Operation and com.zimbra.cs.operation.Requester classes, because this task may take some time to execute.
In Zimbra 8 there's no more Operation nor Requester classes ! And I was unable to find them even in another package.
So now my question: How can I schedule a long time operation in Zimbra 8 as I did in Zimbra 6 ?
Thanks for your anwer.
