When creating multiple faces config files, it is correct to have the faces-config.xml outside of WEB-INF? The JSF spec does not seem to be very clear about this (Section 10.
As mentioned in David's answer, it's not recommended to put the config files outside of the WEB-INF directory. However, if you're looking for ways to organise your project, you might try creating a new subdirectory under WEB-INF.
For example, when I'm dealing with lots of faces-config files, I'll create a directory /WEB-INF/config
and put the faces-config files in there.
