According with @Jesper

You are trying to acces a library that you didn't declare where to found it.

This 't' is a namespace that you didn't daclare.

Example: Here you use <f:view> and this 'f' is a namespace for this URL :

xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"

So you are using a namespace undefined, check out the URL for this namespace 't'

Try this:

xmlns:t="http://myfaces.apache.org/tomahawk"
