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() {
}

}





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?    <<Less
