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
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, 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.
Kind Regards

I am seeing this form another person, and am taking a look at it. Did you ever resolve it?
