You need to specify a component mapping in your faces-config.xml. Note the default components are all mapped in a faces-config.xml that ships with the JAR file. So this default config sets up all of the components for you.
If you want to provide your own (as you are trying to do) you need to override the component in question in the faces-config.xml that goes in your WEB-INF directory. You configure the XML exactly the same as for any component and renderkit that you configure through JSF (so any tutorial/book covering that topic should be able to help.)
