    Seam 3 exception handler - redirection doesn't work

      Hi, I'm not entirely sure if this is the right place to ask (so I'm sorry if it isn't), but..

      What can be cause of not working redirection in this case?

      @HandlesExceptions
      public class ExceptionHandler {
                public void handleException(@Handles CaughtException<Throwable> e,
                                            Messages messages      
                                            FacesContext facesContext){

              messages      .error("something went wrong");
              facesContext      .getApplication().getNavigationHandler()    
                            .handleNavigation(facesContext, null, "errorpage");
                }
      }

      Handler method is processed, but how can I redirect to some error page in exception handler method?  I'm working on school project and according to everything what was presented in course (and what I was able to figure out from documentation) this should work.

          Pretty sure I've answered this post a time or two in other posts.

            They're teaching you Seam 3 in school? That's pretty cool.

             

            As far as I know this should work at that phase. Do you have any exceptions that happen? What can you see when you're debugging?

              Oh, it seems like I had deleted my post right before you answered, I should have edited it instead. I've made redirection work (probabbly some silly mistake because I still don't know what was wrong) .

               

              But I would be glad if u can help me with one more thing. Is there a way to set http status code before redirect? Something other then this

               

                ExternalContext ex = facesContext.getExternalContext();
        ex.setResponseStatus(403);
        ex.setResponseHeader("location", "/403");
        facesContext.responseComplete();

               

              Because if I'm correct, this can used with neither NavigationHandler#handleNavigation() nor with ExternalContext#redirect() - it would set status code back to 200.

               

               

              BTW: Yes, they're teaching us Seam 3 (also infinispan and other interesting things). It's a course taught by Red Hat staff.

                You'll need to call the requestComplete() method on FacesContext.

                Looks like someone didn't get the message that

                  There is no such method as requestComplete() defined on FacesContext. See doc http://docs.oracle.com/javaee/6/api/javax/faces/context/FacesContext.html

                    Sorry, was going off memory. it's responseComplete()
