Am trying to get a simple hello world XMLRPC server setup to work.However I get this Failed to parse response error error when I run the test URL http://localhost/client/index/ on my browser

In my Rpc Controller that handles all my XMLRPC calls

class RpcController extends Zend_Controller_Action
{
    public function init()
    {
        $this->_helper->layout->disableLayout();
        $this->_helper->viewRenderer->setNoRender();
    }

    public function xmlrpcAction()
    {
        $server = new Zend_XmlRpc_Server();
        $server->setClass('Service_Rpctest','test');
        $server->handle();
    }
}

In my client Controller that calls the XMLRPC Server

class ClientController extends Zend_Controller_Action
{

    public function indexAction()
    {
      $clientrpc = new Zend_XmlRpc_Client('http://localhost/rpc/xmlrpc/');
      //Render Output to the view   
      $this->view->rpcvalue = $clientrpc->call('test.sayHello');
    }
}

In my Service_Rpctest function

<?php
class Service_Rpctest
{
    /**
    * Return the Hello String
    * 
    * @return string
    */  
    public function sayHello()
    {
        $value = 'Hello';
        return $value;
    }

}

What am I missing?
