    Since Mojarra 2.1.19 and Mojarra 2.2.0-m10 it's possible to disable the state saving on a per-view basis by setting the transient attribute of <f:view> to true.

    <f:view transient="true">
        ...
        <h:form>
            ...
        </h:form>
        ...
    </f:view>

    JSF is a component based framework which is heavily stateful - so you need the state somewhere, either sent to the client over the wire and posted in again, or on the server side. So AFAIK the answer is No, you cannot disable the View state. But you can minimize it - however some state will always need storing. This link is relevant.

    If you're looking for a Java web framework which is not so stateful - then maybe look at some Action based framework like Struts or Stripes, so you can work in Request scope and not need a component tree present (or rebuilt) on a postback. The Play framework has been gaining good press - which is specifically designed to target RESTful architectures. I do not have experience of this myself, but you may want to investigate it. Taken from the Play website:

    You’ve got a database on one side and a web browser on the other. Why should you have a state in between?

    Stateful and component based Java Web frameworks make it easy to automatically save page state, but that brings a lot of other problems: what happens if the user opens a second window? What if the user hits the browser back button?
