zend framework 提供的webservices,该如何处理

zend framework 提供的webservices
谁有这样的完整的例子。用到Zend_Soap_Server 等zend framework提供的soap扩展的。
想学一下，哪位大侠给提供一些资料，例子的更好啊。最好是那种能运行的简单小例子，谢谢啦
------解决方案--------------------
application/controllers/WebServiceController.php

class WebServiceController extends Zend_Controller_Action {

	public function init() {

    	$this->_helper->viewRenderer->setNoRender();

	}

	

	public function indexAction() {

		if (isset($_GET['wsdl'])) {

			$autodiscover = new Zend_Soap_AutoDiscover();	

		    $autodiscover->setClass('Service_Helloworld');

		    $autodiscover->handle();

		} else {

		    $soap = new Zend_Soap_Server("http://zf-demo.localhost/WebService/index/?wsdl");

		    $soap->setClass('Service_Helloworld');

		    $soap->handle();

		}

	}

	

	public function testAction() {

		$params = array(

			'name' => 'tom'

		);

		

		$client = new SoapClient("http://zf-demo.localhost/WebService/index/?wsdl", array('trace' => 1));

		echo $client->__soapCall('sayHello', $params);

	}

	

}

class Service_Helloworld {

	/**

	 * say hello

	 * @param string $name

	 * @return string

	 */

	public function sayHello($name) {

		return 'hello ' . $name;

	}

}
