## Overview

This is a JavaServer Faces movie-catalog application: users can register films, actors, and genres, with JavaBeans coordinating entity-specific DAOs and JPA-backed domain entities. The sampled code shows the bean-to-DAO and DAO-to-JPA factory calls, plus film associations to actors and genres. The XHTML pages and persistence configuration were not sampled, so links from page submissions to beans and from JPA to a backing store are not asserted.

Main entry points: [`src/br/com/aula/dao/AtorDAO.java`](https://github.com/viniciuslinsgit/locadora/blob/master/src/br/com/aula/dao/AtorDAO.java) (Actor DAO), [`src/br/com/aula/dao/FilmeDAO.java`](https://github.com/viniciuslinsgit/locadora/blob/master/src/br/com/aula/dao/FilmeDAO.java) (Film DAO), [`src/br/com/aula/dao/GeneroDAO.java`](https://github.com/viniciuslinsgit/locadora/blob/master/src/br/com/aula/dao/GeneroDAO.java) (Genre DAO), [`src/br/com/aula/model/Filme.java`](https://github.com/viniciuslinsgit/locadora/blob/master/src/br/com/aula/model/Filme.java) (Film entity)
