NullPointerException at com.sun.faces.application.view.FaceletViewHandlingStrategy.createView

Question

i am trying to upgrade from jsf 1.2 to jsf 2.2.2 on websphere 8.5.1 and what i did is as follows:

1- put jsf-api-2.2.2.jar and jsf-impl-2.2.2.ja

Answer 1

Also faced with same error during migration Struts 1 -> JSF 2.2 It was occurred by ViewHandlerImpl of struts-faces (1.3.8). Looks like this lib is incompatible with Servlet 3 (which is required by JSF 2.2)

PS: Was working with JSF 2.0 without any changes.

So I can suggest to check all 3rd part filters etc., which can be involved to request processing.
