Задача получения Камунды
У меня есть вопрос, я определил следующий процесс в Камунде.
И развернул сервлет на том же сервере приложений, который позволяет мне легко отправлять сигналы развернутому процессу.
Однако каждый раз, когда я вызываю метод сигнала, используя идентификатор экземпляра процесса, я получаю исключение
