Unable to read schema document

[steghio]

Greetings,

I'm using libvirt4occi on Ubuntu 11.10. I installed it via software center and I installed the qemu-kvm and libvirt-bin dependencies via terminal. I started it with sudo /etc/init.d/libvirt4occi start. I'm working behind a proxy which requires authentication.

I can start it properly with no errors. netstat -a | grep 8182 shows someone is listening on that port but then, when I send a sample request (Query Interface->GET) from the Chrome "Simple OCCI client" extension, I get 500 internal server error:

HTTP/1.1 500 Internal Server Error

netstat shows that there's a connection established on 8182

That exception occurs when I try any of the three example operations.

I think I'm missing something here, could you help?

Thank you,

I guess Spring is not properly installed; I cc:ed the developers -- they might be able to help you out.

Cheers,

thank you for your reply. Why would I have to install Spring? I'm using the compiled and bundled version I downloaded here on Github, I didn't compile it from source.

Plus, it always happens when trying to read that particular file but changing the beans.xml in /usr/share/libvirt4occi/conf to make it read the 3.1 file didn't work.

I guess it's because Compute.java under occi4java\infrastructure\src\main\java\occi\infrastructure at line 111 has:

private static XmlBeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource("occiConfig.xml"));

which always tries to read occi4java\infrastructure\src\main\resources\occiConfig.xml which has this line inside:

which refers statically to 3.0 version
