Привет All!
не получается распарсить xml-файл который загружается на сервер через web-форму.
для обработки загрузки файла использую пакет org.apache.commons.fileupload
Подскажите плз знающие, куда копать.
PS: парсер отдельно от сервлета работает (причем с тем же xml-файлом который я пытаюсь загрузить через форму).
выдается ошибка:
