Try putting <jsp:setProperty> outside the <jsp:useBean> tag:
<jsp:useBean id="addrform" class="AddrBean" scope="session" />
<jsp:setProperty name="addrform" property="*" />
The <jsp:setProperty> inside the <jsp:useBean> is executed only if the
class is not yet instantiated. Also, don't forget to include
<%@ page session="true" %>
on the pages that share the object.
It worked for me - I've been checking and debugging my JSP pages and
classes for three days when I found it explained somewhere in the JSP
specification...
