JSF preguntas y respuestas de entrevista
Question: How to get current page URL from backing bean?Answer: You can get a reference to the HTTP request object via FacesContext like this:FacesContext fc = FacesContext.getCurrentInstance(); HttpServletRequest request = (HttpServletRequest) fc.getExternalContext().getRequest(); and then use the normal request methods to obtain path information. Alternatively, context.getViewRoot().getViewId(); will return you the name of the current JSP (JSF view IDs are basically just JSP path names). |
