Although I crawled through these four SO questions, I still only get a blank page when the first JSF page I created within my servlet is called. It is deployed via IntelliJ IDEA on a Tomcat 7 server. On Error Log level "all", I don't get any error messages. The source code in the browser stays completely empty. It seems like FacesServlet isn't invoked, but IMO it can't be due to the url-mapping, it seems OK to me!?? Is there any other possibility, also as for looking into an error log?

It's called in my DispatcherServlet just with
response.sendRedirect("admin/diagnosesedit.xhtml");
from a jsp file which is in the same directory.

In my dependencies, Mojarra-1.2 and javax.faces:javax-faces-api:2.2 are included under the "Provided" scope (changing that to "compile" doesn't change anything).
