запуск приложения wicket на сервере приложений oracle (10g)

Я написал приложение калитки, и локально оно работает отлично. Но когда я развертываю его на сервере приложений оракула (10g), я получаю эту ошибку:

Я использую Wicket+Широ

Что я должен делать? Может быть, это потому, что я использую фильтр калитки?
