jsf - javax.faces.view.facelets.FaceletException: Error Parsing /my.xhtml: Error Traced[line: 42] The prefix "f" for element "f:facet" is not bound -

-

i create table can display data database jsf page. found code:

<h:datatable value="#{bookstore.items}" var="store">   <h:column>     <f:facet name="header">       <h:outputtext  value="#{msg.storenamelabel}"/>     </f:facet>     <h:outputtext value="#{store.name}"/>   </h:column>   <h:column>     <f:facet name="header">       subject     </f:facet>     <h:outputtext value="#{store.subject}"/>   </h:column>   <h:column>     <f:facet name="header">       <h:outputtext  value="#{msg.storepricelabel}"/>     </f:facet>     <h:outputtext value="#{store.price}"/>   </h:column> </h:datatable>

when use code error message in netbeans:

javax.faces.view.facelets.faceletexception: error parsing /my.xhtml: error traced[line: 42] prefix "f" element "f:facet" not bound

if replace f tag h tag, going work? or have include f tag library?

you have inlude correct taglib f prefix.

here example jsf 2.2 facelet page:

<!doctype html> <html xmlns="http://www.w3.org/1999/xhtml"       xmlns:ui="http://xmlns.jcp.org/jsf/facelets"       xmlns:h="http://xmlns.jcp.org/jsf/html"       xmlns:f="http://xmlns.jcp.org/jsf/core">  ... </html>

in case you're still on jsf 2.0/2.1, use java.sun.com domain instead of xmlns.jcp.org domain in xml namespace.

i recommend read jsf tutorial, can find links in our jsf wiki page.
