Accessing FederationPrincipal from a Filter in Fediz Plugin

[Gina Choi]

Hi All,

I took fediz-1.0.1 which was great since it included cxf2.6.2 and
wss4j-1.6.7.jar. I placed a filter behind FederationFiter try to access
claims from FederationPrincipal using following code. But it says that
Principle p is not an instance of FederationPrincipal. I didn't have this
problem from either Servlet or JSP. I am able to set security token using
SecurityTokenThreadLocal.getToken(), but as you know getting claims using
FederationPrincipal is much simpler. Could someone let me know why do I
have problem inside a Filter?

    public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse,
            FilterChain filterChain) throws IOException, ServletException {
        // TODO Auto-generated method stub

        // make sure we are dealing with HTTP
        if (servletRequest instanceof HttpServletRequest) {
            HttpServletRequest request = (HttpServletRequest)
servletRequest;
            HttpServletResponse response = (HttpServletResponse)
servletResponse;

                 Principal p = request.getUserPrincipal();
                 System.out.println("Principal is not instance of
FederationPrincipal:" + p.getName());

                    if (p instanceof FederationPrincipal) {
                        FederationPrincipal fp = (FederationPrincipal)p;
                        ClaimCollection claims = fp.getClaims();
                        for (Claim c: claims) {
                            System.out.println(c.getClaimType().toString()
+ ": " + c.getValue());
                        }
                    } else {
                        System.out.println("Principal is not instance of
FederationPrincipal:" + p.getName());
                    }
                    Element el = SecurityTokenThreadLocal.getToken();


Thanks in advance.
