Oi gente, to tentando fazer um sistema de login de usuarios usando um Filtro, minha aplicação é feita em JSF e Hibernate, porém toda vez que inicializo ela, obtenho um erro
java.lang.IllegalStateException

<!-- The bare minimum needed for JSF 2.0 is a servlet 2.5
declaration and the mapping for the FacesServlet.
Setting PROJECT_STAGE to Development is highly recommended
during initial development so that you get more helpful
error messages.
