Hi,

I'm using Eclipse 3.4.0 ganymede with JSF 1.2, Dynamic Web Module 2.5 and Facelets and RichFaces 3.2.2, Tomcat 6.0.

I'm developing a Facebook app. I´m implementing the Authentication layer in custom filter:

			

			public class FaceBookAuthFilter implements Filter {
			

			private String _apiKey;
			

			private String _secretKey;
			

			public void init(final FilterConfig filterConfig){
			

			_apiKey = filterConfig.getInitParameter("api_key");
			

			_secretKey = filterConfig.getInitParameter("secret_key");
			

			}
			

			

			/**
			

			* Verifies whether user is logged in. If not, sends user to the login page.
			

			*/
			

			public void doFilter(final ServletRequest request, final ServletResponse response, FilterChain chai
			

			n) throws IOException, ServletException {
			

			HttpServletRequest httpReq = (HttpServletRequest) request;
			

			HttpServletResponse httpRes = (HttpServletResponse) response;
			

			try {
			

			FacebookXmlRestClient authClient = FaceBookAuthHandler.getAuthenticatedClient(httpReq, _apiKey, _
			

			secretKey);
			

			request.setAttribute("auth.client", authClient);
			

			chain.doFilter(request, response);
			

			} catch (FailedLoginException fle) {
			

			//user not logged in
			

			forceLogin(httpRes);
			

			

			} catch (Exception e) {
			

			//handle exception
			

			System.out.println(e.toString());
			

			}
			

			}
			

			

			/**
			

			* Sends user to login page
			

			* @param response
			

			*/
			

			private void forceLogin(HttpServletResponse response) {
			

			try  {
			

			response.sendRedirect ("http://www.facebook.com/login.php?api_key=" + _apiKey + "&v=1.0");
			

			} catch (IOException ioe) {
			

			//handle exception
			

			}
			

			}
			

			

			public void destroy() {
			

			}
			

			

			}
