The JSF tags invoke the encode methods on the component. The latest version of JSF (1.2) first creates the component tree and then invokes rendering. The JSP tags only create the tree and the tree is rendered using a encodeAll method on the view root by the lifecycle. The Clay example is in between the two JSF versions - implemented prior to JSF 1.2 was drafted. It doesn't use JSP to build the view. If you want JSP to build your view, you will need to dispatch to the JSP after you have replaced the response writer with your own. In your custom view handler, I would try overriding the renderView method while delegating to the original for the other methods. In the renderView, pipe the response writer to a local buffer and use the external context to dispatch to the viewId (JSP page) [1]. Under JSF 1.1 your response writer should be populated with the rendered markup.
