OmniFaces Showcase

Collection of utility methods for the Servlet API in general. Most of them are internally used by Faces and FacesLocal, however they may also be useful in a "plain vanilla" servlet or servlet filter.

There are as of now also five special methods related to Faces without needing a FacesContext:

• The getFacesLifecycle(ServletContext) which returns the Faces lifecycle, allowing you a.o. to programmatically register Faces application's phase listeners.
• The isFacesAjaxRequest(HttpServletRequest) which is capable of checking if the current request is a Faces ajax request.
• The isFacesResourceRequest(HttpServletRequest) which is capable of checking if the current request is a Faces resource request.
• The facesRedirect(HttpServletRequest, HttpServletResponse, String, Object...) which is capable of distinguishing Faces ajax requests from regular requests and altering the redirect logic on it, exactly like as ExternalContext.redirect(String) does. In other words, this method behaves exactly the same as Faces.redirect(String, Object...).
• The isFacesDevelopment(ServletContext) which is capable of checking if the current Faces application configuration is set to development project stage.

Those methods can be used in for example a servlet filter.
