мы используем BlazeDS в качестве прокси между Flex и Java. Подход такой же, как в (http://www.flexpasta.com/index.php/2008/05/16/exception-handling-with-blazeds-and-flex/)
Объявление исключения Java:
public class FlexException extends RuntimeException {
private String name = 'John';
public FlexException(String message) {
super(message);
}
public String getName() {
return name;
}
}
Затем мы бросаем это:
public void testMethod(String str) throws Exception {
throw new FlexException("Custom exception");
}
Гибкая часть:
private function faultHandler(event:FaultEvent):void
{
var errorMessage:ErrorMessage = event.message as ErrorMessage;
trace("error++");
}
и здесь создается экземпляр удаленного объекта:
<mx:RemoteObject id="mySample" destination="mySample" channelSet="{cs1}" fault="faultHandler(event)" />
Но в event.fault я получаю «Server.Processing» и event.faultString равно «Произошел необработанный сбой на сервере. Произвольное исключение»
Как я могу получить данные, указанные в реквизитах исключений?

Вот что я получаю во Flex при установке точки останова в onFaultHandler:
Итак, вопрос в том, почему rootClause имеет значение null? Где моя FlexException с именем = 'Джон'.
