O erro ocorre dentro do doFilter.

Seria alguma propriedade no xml? ou talvez a forma que esta implementado o doFilter?

#2

Onde dá a exceção ?

Na hora do commit ?

#3

A exeção ocorre na seguinte linha do doFilter:

Esqueci de falar, to usando o TomCat 6 sera que pode ser isso?
Vale mudar para o TomCat 7?
Abraço

#4

As lib’s estão no tomcat corretamente não é ?

Vê se o getCurrentSession traz algo.

#5

Então, as lib´s estão tudo certo.
E o getCurrentSession tambem vem preenchido.
Estou no trabalho agora, mas asim que chegar em casa vou alterar para o TomCat 7, pra ver se resolve.
