[vbox-dev] Exception calling IMachine.getName() through java webservice API

[Nikolay Igotti]

    Hi Gerry,


 Are you sure that user starting vboxweb.exe indeed is allowed to access 
and modify your virtual machine files? Just for test, can you try to 
rename .VirtualBox directory in your home directory, and create few new 
VMs from scratch, and see if problem persists.
If not, then likely some of your xmls/vdis are corrupted or not 
accessible. Can you access VMs from the VBox own GUI?

 Nikolay.
