Erro no Xwork com controller para swing

Estou tendo uns erros muito esquisitos trabalhando com Xwork como controller para swing. fui cercando o problema até chegar a conclusão que ele nao esta carregando o xwork.xml

Alguem tem alguma ideia de como resolver isso ?

1 - o xwork ta no classpath
2 - as ações requisitadas estao no xwork
3 - alerta esquisito com.opensymphony.xwork.config.ConfigurationException: There is no result type defined for type 'mainFrame' mapped with name 'success'

Erros
