Comparativo "session" JSP y JSF

I.- SETEAR EN SESION:

A.- JSP: request.getSession().setAttribute("miVariable",valor);

B.- JSF: FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("miVariable", valor);


II.- RECUPERAR LA SESION:

A.- JSP: request.getSession().getAttribute("miVariable");

B.- JSF: FacesContext.getCurrentInstance().getExternalContext().getSessionMap().get("miVariable");


III.- RECUPERANDO 'Context, Request, Response':

A.- JSP: En JSP es automatico al utilizar los Servlet.

B.- JSF: Se tiene que simular el manejo 'Context, Resquest, Response' tanto para el HttpServlet o el Servlet, segun se requiera.


- FacesContext context = FacesContext.getCurrentInstance();

- HttpServletRequest request = (HttpServletRequest)context.getCurrentInstance().getExternalContext().getRequest();

- HttpServletResponse response = (HttpServletResponse)context.getExternalContext().getResponse();

- ServletContext request2 = (ServletContext)context.getCurrentInstance().getExternalContext().getRequest();

- ServletContext sContext = (ServletContext)context.getExternalContext().getContext();

- ServletRequest sRequest = (ServletRequest)context.getExternalContext().getRequest();

- ServletResponse sResponse = (ServletResponse)context.getExternalContext().getResponse();
