You can simply access the HttpServletResponse OutputStream directly from a
faces-javaBean method, called when a specific JSF viewId (the URL of the
image) is accessed... from there you can call
facesContext.responseComplete() after the image has been streamed. That's a
way around using a custom servlet, and still gaining access to the faces
lifecycle (should you choose.) though it will likely be less efficient than
a thin servlet-based implementation.
