That's not quite true. - what if you do this
<jsp:useBean id="foo" scope="request" />
<jsp:setProperty name="foo />
and you do a
<jsp:Include name="bar.jsp" /> and bar.jsp also has the above code!
This means the above property will be reset by bar.jsp - not what you want
at all.
If you are using <jsp:setProperty ... /> to initialise the bean, use it as
part of the useBean body. There it will have fewer side-effects, and the
bean is better encapsualted.
