Приложение пишется в Rational Application Developer под IBM WebSpher- a.
Подскажите, как в Rational Application Developer включить поддержку ajax.
В общем проблема такая.
Создал портлет (для примера).
В jsp написал

В test.xml написал

<?xml version="1.0" encoding="UTF-8"?>
<root>
I'm a test.
</root>

В итоге жму по ссылке и получаю ошибку.
