Unable to use a filter with redirection for single sign on

["Delbrouck, Henri-Philippe" <he...@siemens.com>]

Hi 

I am using MyFaces 1.0.9 and have configured an authentication filter in
Tomcat 5.0.28 which does a redirect to a single sign on system.
I nevertheless receive the following error:

javax.servlet.ServletException: Unable to use forwarding (forward) after the
response has been sent at
javax.faces.webapp.FacesServlet.service(FacesServlet.java:125) at
org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Application
FilterChain.java:237) at
org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterCh
ain.java:157) at
eu.cec.trade.sigl2.filters.GacaAuthenticationFilter.doFilter(GacaAuthenticat
ionFilter.java:58) 
This does not happen if I use a jsp page in the request. When I use a jsf
page and activate thus the jsf servlet, I receive the previous error.

Has anybody an idea of the problem ?
