Fediz simpleWebapp doesn't work as expected - saml-2.0

Question

I've set up two Tomcat servers as described in the README's and the http://cxf.apache.org/ site. The tests for the IDP server work; I can see the WSDL for the web service. But when I go to https://localhost:8443/fedizhelloworld/secure/fedservlet, I just get a blank page.
The log output of the IDP server says:
16:56:45.379 [http-nio-9080-exec-7] DEBUG o.a.c.a.AuthenticatorBase - Security checking request GET /fediz-idp-sts/REALMA/STSServiceTransport
16:56:45.380 [http-nio-9080-exec-7] DEBUG org.apache.catalina.realm.RealmBase - No applicable constraints defined
16:56:45.381 [http-nio-9080-exec-7] DEBUG o.a.c.a.AuthenticatorBase - Not subject to any constraint
On the RP server, I see:

The README promises:
The browser is redirected to the IDP and prompts for username and password.
but I just get a blank page with the URL https://localhost:9443/fediz-idp/federation?wa=wsignin1.0&wreply=https%3A%2F%2Flocalhost%3A8443%2Ffedizhelloworld%2Fsecure%2Ffedservlet&wtrealm=urn%3Aorg%3Aapache%3Acxf%3Afediz%3Afedizhelloworld&wct=2015-12-03T15%3A58%3A04.942Z&wctx=b6ae9556-5e4f-49ca-a9ee-493403cf1ab3
My guess is that there is something wrong with the configuration but what?

Answer 1

Make sure you have both WARs (fediz-idp.war and fediz-idp-sts.war) deployed on the IDP server.
When you have, you should see this output right after Not subject to any constraint:
