tentou tirar o context-param de packages e deixar só o filtro?
Parece que tinha alguns erros escondidos aqui e eu consegui achar.
Olha só
SEVERE: Exception starting filter vraptor

... 63 moreSe vc ler o erro vc consegue ver o que está acontecendo:
Unable to load class [ ccc.cefetmg.ipman.model.Department] declared in Hibernate configuration <mapping/> entry …
Caused by: java.lang.ClassNotFoundException: ccc.cefetmg.ipman.model.Department ou seja, essa classe não existe… deve estar com o nome ou o pacote errado, no mapeamento do hibernate.
Mas ta perfeito … tanto que localmente eu consigo rodar
essa classe está no war/jar/ear deployado no servidor?
Desculpa a ignorância mas é a primeira vez que to tentando fazer isso.
O quer dizer com isso ? Aonde devo olhar ?
como vc está fazendo o deploy no servidor?
Navegando em
war/WEB-INF/classes/ccc/cefetmg/ipman/model não tem classe nenhuma ? Que bruxaria é essa? kkk
Sei lah 
tenta dar um clean no projeto e no servidor
Apache Tomcat … Numa seção que chama Manager App
Nada kkkkk
Cara… eu fiz uma loucura aqui
Eu gerei um .war na mão … daí copie desse war pro war que o netbeans gera as classes do modelo que tavam faltando … ai deu tudo certo … só que to sem acesso ao banco aqui ai ta dando alguns erros.
Mas gostaria de saber pq o netbeans ao construir o projeto e criar o war não ta fazendo isso certo
mas vc gera um war ou coisa do tipo?
