Banging my head after few hours, i figured out that I was calling limpiarFormulario() before it get initiated/born. So I was getting a null pointer in utilEJB class. The idea seems to be that I need to use the @PostConstruct init method to call the limpiarFormulario() since the EJB are already injected. The problem is that the @PostConstruct is never called.
