объекты при работе через LS2J При попытке вызова NotesFactory.createSession() в java коде, вызванном через бридж, бросается исключение NotesException: Cannot create a session from an agent. Поверхностное гугление подтверждает этот вывод: Julie Kadashevich ( Software Engineer, IBM ), в своем посте на форуме IBM прямо отвечает на вопрос о возможности создания domino объектов в LS2J: this is an architectural limitation Г-же Кадашевич можно доверять - она явно не случайный пассажир на форуме ibm. Если честно, доступ к доминошным объекта в ls2j не особо и нужен: предполагается, что манипуляции над domino объектами нужно производить lotusscript, а java bridge подключается для решения вспомогательных задач, которые не могут быть эффективно решены на ls. В качестве примеров использование LS2J можно привести: использование регулярных выражений работа с буфером обмена обработка изображений работа с Zip архивами Неплохая подборка есть на nsftools Появление LS2J значительно упростило жизнь разработчику. Однако, при пользовании нужно помнить про ограничения, упомянутые в хелпе и про то, что мы не можем использовать notes объекты при работе через LS2J Или все-таки можем?😉 Цитата из хелпа дизайнера There are a few limitations with LS2J: You may not delete a Variant containing a JavaClass object. There are some data type limitations (see Data type mappings). LotusScript property names are case insensitive, but Java property names are case sensitive. If two J
