java.lang.IllegalStateException: Could not find backup for factory javax.faces.application.ApplicationFactory [duplicate]

Answer 1

See @BalusC answer here about the same problem. You have two jsf implementations in your pom.xml: myfaces and mojarra. So myfaces is conflicting with mojarra. Remove one of them

    org.apache.myfaces.core
    myfaces-api
    2.2.2



    org.apache.myfaces.core
    myfaces-impl
    2.2.2



    org.apache.myfaces.core
    myfaces-bundle
    2.2.2

or

    com.sun.faces
    jsf-api
    2.2.2


    com.sun.faces
    jsf-impl
    2.2.2
