[libvirt-users] Using Java bindings to event callback

Hi My test environment : CentOS 6.3 6.4 Ubuntu 13.10 For CentOS 6.4 libvirt-java-0.4.9-1.el6.noarch libvirt-python-0.10.2-29.el6.x86_64 libvirt-client-0.10.2-29.el6.x86_64 libvirt-0.10.2-29.el6.x86_64 I am try to use java bindings to event callback. int register = conn.domainEventRegisterAny(null, 0, cb); But always get the following error message: libvirt: Remote Driver error : adding cb to list exception caught:org.libvirt.LibvirtException: adding cb to list level:VIR_ERR_ERROR code:VIR_ERR_RPC domain:VIR_FROM_REMOTE hasConn:false hasDom:false hasNet:false message:adding cb to list str1:%s str2:adding cb to list str3:null int1:-1 int2:-1 By the way I also trace the mail list *[libvirt] [PATCH] Java bindings for domain events* (2008 Nov 07) *[libvirt] [PATCH 1/2] Java bindings for domain events**[libvirt] [PATCH 2/2] Java bindings for domain events* (2008 Nov 18) --> Reject patch*Re: [libvirt] [PATCH 1/2] Java bindings for domain events* (2008 Dec) —>No Result*[libvirt-users] Using Java bindings to event callback * (2010 Jul) —>No Result *[libvirt] [PATCH 0/2] Libvirt-java event handling (2011Jul)* —> I think most drivers don't support that.
