Re: [Xen-API] Java XML RPC with Xen-API?

[Evan Bigall <evan.bigall@xxxxxxxxxxx>]

Apache xmlrpc-3.0, and their internal transport, ie: m_client.setTransportFactory(new XmlRpcCommonsTransportFactory(m_client)).  I had started out using Java's http transport, but ran into problems.  Sorry, can't quite remember what they were.

I would hope so, too, but it results in a ClassCastException. Which XML RPC library are you using and what version?
