It seems rather weird to me for the browser to invoke code on the server like
this. I cannot imagine why you would want to do this.
However you can also use XmlHttpRequest from javascript to invoke stuff on the
server. This can be coded directly or you can use something like "Shale
Remoting". It appears to me that you are trying to invoke a *method* on the
server rather than fetch a *page*. While a jsf page can be abused to trigger a
method by "clicking a button", it is nicer to avoid misusing JSF, and use
XmlHttpRequest or remoting.
