Я использую Glassfish 2.1.1. Я наблюдал таинственную обработку вызовов http / webservice. Он отправляет запрос http, который обрабатывается двумя разными потоками.
После простой аутентификации http первый поток работает быстрее. Сохранение некоторых данных завершается, но во внутреннем стекле не получается записать ответ.
Второй поток завершается ошибкой, потому что он пытается сохранить идентичные данные, и существуют (уникальные) ошибки ограничения. Ответ (сбой) второго потока был доставлен клиенту.
Я не буду обсуждать поведение с уникальной ошибкой ограничения. Я улучшил веб-сервис, так что он может справиться с этим лучше, потому что это может произойти в любое время, когда клиент отправит вызов ws во второй раз.
Но я думаю, у Glassfish 2.1.1 есть ошибка обработки http-запроса. Есть ли известная проблема? Я сделал ошибку?
