немного разобрался с сервлетами и jsp, решил посмотреть jsf
и сразу проблема...
взял пример из туториала, деплою на томкате и открывая index.faces получаю такой эксепшн

ошибка в этой строке
| Код |
<h:inputText value="#{user.name}"/>
|
никак не могу понять в чем причина ошибки...
все перепробовал и с myfaces 1.1/1.2 и с сановским jsf 1.1 на томкэте 5.5.20/6.0.10 jdk 1.5.0_07/1.6.0_02
везде один и тот же эксепшн...
даже гугл не помог))
уже три дня мучаюсь, думаю уж забить на jsf и пойти тапестри или еще чегонибудь смотреть))
