Я интегрирую приложение на основе окон с помощью java-приложения и хочу захватить события окна в java.Как зарегистрироваться для событий WMI с помощью Java
Я нашел в google J-Interop библиотеку, которая может быть достигнута. я сделал некоторую СПЭ WIH ниже кода, но перед проблемой при размещении службы т.е. WbemScripting.SWbemLocator
