<div class="gmail_quote">Hello all, I've been posting questions about my issue to the user list but it seems nobody can answer, so I had to try this list, sorry if there is any disturbance. Here is the case: I've been trying to develop a java app that can register callbacks for domain lifecycle events(suspend,resume,etc.). Only method that I've seen is Connect.VirDomainEventRegisterAny, and there is an abstract callback method inside VirConnectDomainEventGenericCallback. I implement the callback, and register it for all the domains by passing the domain pointer as NULL. Additionally for testing, I've added a println into the suspend function in org.libvirt.Domain.java, and compiled the java bindings and used the new jar file, and I was successful, I can see the message whenever I suspend the domain either by clicking pause or by writing dom.suspend() in my java app. However, when I try to register a callback as I mentioned in the beginning (with eventID 0, which is life_cycle ID), after the suspend operation, I get the error that you can see at the end of the mail. But before you check it out, I have to ask, are some of the event-related features of libvirt missing in java bindings? For example; VirEventAddHandleFunc, VirEventAddHandleCallback, and their derivatives. Is this a problem or the only Connect.VirDomainEventRegisterAny method of java binding suffice for providing callbacks for domain events? Thanks in advance for your responses. The error is below.
