Could not find backup for factory javax.faces.context.FacesContextFactory Weblogic

Question

I'm using JSF2.1 Mojarra on Weblogic 12c with Servlet 3.0. jsf-api and jsf-impl are NOT in /WEB-INF/lib after build/deploy. I've tried checking for classpath pollution, but don't see anything. This is the error:

java.lang.IllegalStateException: Could not find backup for factory 
 javax.faces.context.FacesContextFactory.

Answer 1

I found the issue. In WEB-INF/faces-config.xml, I had a navigation-handler that was pointing to a class that didn't exist. Correcting this resolved the issue.
