getProperty and useBean

Assume Dog has a property breed, can we get the property by this:
<%
Dog dog=new Dog();
dog.setBreed("spaniel");
session.setAttribute("d",dog);

%>
<jsp:getProperty name="d" property="breed"/>

In other words, without going through <jsp:useBean>.

In tomcat, this does print out "spaniel". However, in JSP spec 5.3


consequence of the previous paragraph is that objects that are stored
in, say, the session by a front component are not automatically
visible to jsp:getProperty actions in that page unless a jsp:useBean, or
some other action, makes them visible.


Can anyone explain the rule relating useBean and getProperty.

Thx
