It's not exposed in JSP (i.e. it's a feature that isn't supported in
JSP). It's only available in JSF 2.0 Facelets [1].
If you need to ajaxify existing JSP+JSF applications, you'll need to use
a component set that offers such services within JSP or use something a
little more low-level such as ajax library provided by jsf-extensions [2].
