Bermi?, anyone?

Can anyone give me a short pointer to how I initilize the AkActionWebServiceServer?

Tried something like this:

class RpcController extends ApplicationController
{
  function index() {
    $server = new AkActionWebServiceServer('xml_rpc');
    $server->addService('TestService');
    $server->init();
    $server->serve();
  }
}

But AkActionWebServiceServer isn't loaded. And I don't want to try to include stuff manually, unless someone tells me to ;P

Any tips?
