ADFUtils y JSFUtils. Dos clases que no pueden faltar en tu proyecto de ADF

En proyectos ADF es muy común que tengamos la necesidad de tener clases que apoyen a una rapida codificación de nuestros proyectos, Aqui les dejo un par de ellas, las cuales es indispensable las tengamos en nuestro proyecto.

A continuación la descripcion de las clases
