Hey Nikolay
Thanks for the tip. I added this in the web.xml:
<security-constraint>
<web-resource-collection>
<web-resource-name>CommunicationChannelUtilWeb</web-resource-name>
<url-pattern>*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<!-- Specify the role that all users must have to access the application -->
<auth-constraint>
<role-name>CommunicationChannelUtilRole</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
and this in the web-j2ee-engine.xml:
<security-role-map>
<role-name>CommunicationChannelUtilRole</role-name>
<server-role-name>Everyone</server-role-name>
</security-role-map>
I think the page now tries to route me to the login page first. 
However If I access the page I get a 500 Internal Server Error. The log shows these Exceptions:
500 Internal Server Error is returned for HTTP request [https://system:port/CommunicationChannelUtilWeb/faces/login.xhtml]:
