Question

I am creating an activation, triggered after clicking an URL in an e-mail from registration.
I would like to execute my bean Activate.java immediately, instead of creating an xhtml page with something like #{validate}.

I do not need any xhtml file because the user will be redirected to login.
What is the best way of achieving this?

Note, I am using JSF 2.0.

Answer 1

Use a servlet.

@WebServlet("/activate")
public class ActivationServlet extends HttpServlet {

   @EJB
   private ActivationService service;

   @Override
   protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
       String key = request.getParameter("key");

       // ...

       response.sendRedirect(request.getContextPath() + "/login.xhtml");
   }

}

This will be invoked when you call http://localhost:8080/contextpath/activate?key=42.

You’ll only miss JSF validation facility as possible with <f:viewParam>. What do you want to do if key is missing or invalid?
