Parece não funcionar com a nova versão do VRaptor. Ainda não analisei as soluções etc. mas o metodo getParameter(String s) não existe no MutableRequest.

Desculpa, erro meu. Não estava importanto o servlet-api.

Could not find a suitable constructor in br.com.caelum.vraptor.http.route.PathAnnotationRoutesParser. Classes must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private.
