Beans

Collection of utility methods for the CDI API that are mainly shortcuts for obtaining stuff from the BeanManager

Components

Collection of utility methods for the JSF API with respect to working with UIComponent. There are several traversal/lookup methods, there are several UIForm and UIInput related methods which makes it easier to deal with forms and inputs
