Corba сортировочного и проксите с помощью writeReplace

Question

Можно создать дубликат:
Is there any equivalent to writeReplace in CORBA?

я в какой-то части моем JavaEE применения самодельной компоненты настойчивости, которая возвращает коллекцию и карты прокси. Этот компонент используется моими EJB, к которым обращаются через веб-службы.

К сожалению, при использовании ленивой карты или коллекции кажется, что возвращаемое значение EJB (которое обычно является возвращаемым значением компонента) не может быть сериализовано реализацией CORBA, используемой Glassfish. на самом деле, каждый раз, когда я пытаюсь вызвать такой methodj, я получаю

Я попытался реализация writeReplace метода в моих доверенных лицах, п, но без видимого результата.

Итак, что я могу сделать, чтобы мои прокси сериализовались, загрузив их значения и вернув их?

Кто-то пытается использовать Java HashMap как объект CORBA, который не будет работать. (См. Последнее исключение). Чтобы предоставить решение вашей проблемы, предоставьте дополнительную информацию (код).
