Bean Class not found - JavaWeb

Good evening, I'm doing my tcc on Java Web and doing data persistence with JPA and Hibernete. I made CRUD seemingly right, but when I click the register button it gives this error.

action="#{empresaController.incluir()}": Target Unreachable, identifier 'empresaController' resolved to null

I believe that that is not finding my class empresaController .

Could anyone help me?

@ManagedBean
@SessionScoped
public class EmpresaController extends BaseController<Empresa>{

    public EmpresaController() {
        super(Empresa.class);
        this.dao = new EmpresaDao();
    }

    @Override
    public void limpar() {
        this.objeto = new Empresa();

    }
    @Override
    public String incluir() {
        return super.incluir(); 
    }
}
