[fw-webservices] Zend_Rest_Server and Zend_Rest_Client error

Hello All.

I am trying to create a Zend_Rest_Server but it is not working and always return a response like that:
<rest generator="zend" version="1.0">
<response>
<message>An unknown error occured. Please try again.</message>
</response>
<status>failed</status>
</rest>

Does anyone have some example? i think i am doing someting wrong but i am following the Documentation and i do not know where i can look for other tutorial/ code example.

Below follow the sources:
Server:
public function indexAction()
    {

        $this->_helper->viewRenderer->

setNoRender();
        $this->_helper->layout->disableLayout();

        $server = new Zend_Rest_Server();
        $server->setClass('Example');
        $server->handle();

    }


Client:
public function clientAction()
    {
        $this->_helper->viewRenderer->setNoRender();
        $this->_helper->layout->disableLayout();

        $client = new Zend_Rest_Client('http://localhost/form/index/index');
        echo $client->hello('adler')->delete();
    }

Example class:
class Example {
    public function hello($nome)
    {
        return "Hello $nome";
    }
   
}
