See the JSP 1.1 specification, http://java.sun.com/products/jsp/
It's described in "5.4.2 Basic Protocol: Tag Interface".

But in the example above, the return is not in the bean, it's in a scriptlet
in the JSP calling the bean. It will therefore end the processing of the
_jspService method in the JSP page implementation class.

There will be more examples as time goes by; note that this is all brand
new stuff. The only JSP containers I know of that implements JSP 1.1 are
Jakarta's Tomcat (http://jakarta.apache.com) and Orion Server
(http://www.orionserver.com).
