Mam problem z jedną stroną JSF. Jest to kod źródłowy:Ostrzeżenie: Ta strona wymaga przestrzeni nazw XML zadeklarowanej z prefiksem [nazwa elementu HTML], ale nie istnieje biblioteka taglibrary dla tej przestrzeni nazw

Czy możesz dać mi pomysł, jak rozwiązać ten problem? Przypuszczam, że problem tkwi w tagach JSF.
Używałem xmlns: h = "ht tp: //xmlns.jcp.org/jsf/html "i otrzymałem powyższy błąd. Kiedy zmieniłem to na xmlns: h = "http://java.sun.com/jsf/html" to działało! Wala! – dirai
Przestrzenie nazw xmlns.jcp.org/* są nowszymi identyfikatorami URI Java EE 7+, zobacz także https://stackoverflow.com/questions/7593603/jstl-xmlns-namespace-differences-between-jsf-1-2 -and-jsf-2-x – Kawu
