Надеюсь все знают что такое WebService, а для тех, кто не в курсе google->WevService+WSDL для начала надо сделать простой webService, например на java ) Нам понадобится tomcat, axis и xerces. Как настроить webService на java - ищем в FAQ, повторятся не буду ) Исходный код сервиса ) | Код |
public class TestService {
public String getName() {
return "This is test service! YO ))))";
}
public String getSumm(int a, int b) {
return String.valueOf(a + b);
}
}

Зы. Ещё нужно скачать либу для flex - cairngorm И соответственно добавить к прожекту ) Переходим к Flex ) Описание нашего сервиса service.mxml | Код |
<?xml version="1.0" encoding="utf-8"?>
<cairngorm:ServiceLocator

Создаём делегат нашего метода, допустим SummDelegate.as | Код |

Модель ) ModelLocator.as | Код |

public class ModelLocator implements com.adobe.cairngorm.model.ModelLocator

public function ModelLocator()

Определим контроллер ) | Код |
import com.adobe.cairngorm.control.FrontController;
public class Controller extends FrontController

public function Controller()

addCommand(SummEvent.SUMM, SummCommand);
