Привет, пытаюсь запустить вместе Spring и Flex, но возникает ошибка:

Причём всё прекрасно работает, если:
1) В application-base.xml вместо бина "customerService", который находится вне данного проекта и вызывается удалённо:
| Код |
<bean id="customerService"
class="org.springframework.remoting.httpinvoker.HttpInvokerProxyFactoryBean">
<property name="serviceUrl"
value="http://${serverName}/${contextPath}/customer.service" />
<property name="serviceInterface" value="service.CustomerService" />
</bean>
|
поставить бин "customerService2", который находится в этом же проекте
| Код |
<bean id="customerService2" class="CustomerServiceImpl"/>
|
2) Если использовать "customerService", но не использовать Flex, а скажем выводить данные в jsp.
Т.е. другими словами сам сервис "customerService" работает нормально, а просто по какой-то причине Flex его не хочет принимать.
Ошибка появляется при добавлении этой стороки:
| Код |
<flex:remoting-destination ref="customerService"/>
|
Причину выяснить не получается, может флекс не может получать удалённую реализацию интерфейса ? - подскажите пожалуйста! |
