Ho un problema con una pagina JSF. Questo è il codice sorgente:Avviso: questa pagina richiede lo spazio dei nomi XML dichiarato con prefisso [nome dell'elemento HTML] ma non esiste alcuna taglierina per tale spazio dei nomi

Quando carico la pagina viene visualizzata questo messaggio di errore in basso nella pagina:

potete darmi idea di come risolvere il problema? Suppongo che il problema sia nei tag JSF.
Stavo usando xmlns: h = "ht tp: //xmlns.jcp.org/jsf/html "e ho ricevuto l'errore sopra riportato. Quando l'ho modificato in xmlns: h = "http://java.sun.com/jsf/html" ha funzionato! Wala! Gli spazi dei nomi – dirai
"xmlns.jcp.org/*" sono gli URI Java EE 7+ più recenti, vedi anche https://stackoverflow.com/questions/7593603/jstl-xmlns-namespace-differences-between-jsf-1-2 -e-jsf-2-x – Kawu
