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

Question

I would like to create table which can display data from database into JSF page. I found this 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 I use this code I get this error message in Netbeans:

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

If I replace the f tag with h tag, is it going to work? Or do I have to include f tag library?

You have to inlude the correct taglib for the f prefix.

Here is an example for a 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 to read a JSF tutorial, you can find links in our JSF wiki page.

Replacing the f with h won't work, since there's no h:facet (in the JSF html taglib which is likely to be assigned to the h prefix). You'll have to include the appropriate taglib (JSF core) and assign it to the f prefix.

Include taglib. <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
