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.

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 chain) 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() {
 }

}

This is what I have in web.xml

Adding the custom filter I receive a blank page, richfaces don´t work propertly. How can I integrate propertly the custom filter, without having conflict with RichFaces filter?
