[libvirt-users] java binding

Hi all, I'm trying to use the libvirt event system in order to notify the VM status (VM boot, reboot, crash, etc.). I must use the java binding, so I exposed some calls not present in "Libvirt-java" jna interface: virEventRunDefaultImpl() virEventRegisterDefaultImpl() (and several costant). In my java source I tried to intercept the event, using the "Connection.domainEventRegisterAny( ... )" call , but the "answer" was: "this function is not supported by the connection driver: no event support". No errors issued on the virEventRunDefaultImpl and virEventRegisterDefaultImpl (moreover, both the calls return "0" ). I do not know the libvirt internals, so my question is : it is possible to call the libvirt events calls using java binding? Can you tell me the issues involved in this task? I'm thinking to build a native library and use jni or use jython as alternatives. Thanks, Maurizio
