Как получить значение радио кнопки или checkboxa на сервлете?
Например в -"Recieve email news?"- я выбрала "Yes", после нажатия на кнопку "Registrate", на новой страничке вывелось Yes, но помимо этого еще высвечивается "null"(вместо No). Как сделать так, чтобы на сгенирированной страничке появлялось то, что я выбрала на главной странице регистрации?)
Вообще для этих целей (Yes/No) достаточно одного checkbox'a, значение которого нужно проверять при отрисовке страницы. Или использовать два элемента, но radio-типа. И кодом такие вопросы надо снабжать...
