Hi,
I don't know about you but I've never seen a classname/package name that
looked like a function before ;-)
put
<%@ page import="Package.className" %>
<jsp:useBean id="CFBean" scope="request" class="Package.className" />
<jsp:setProperty name="CFBean" property="*" />
</jsp:useBean>
at the top of your JSP page
then you could do a
<% String l_id = (String)session.getValue("f_id");
CFBean.setSession(l_id);
%>
This is prividing that your bean has a setSession(String id) method.
remember that beans should not have a constructor that takes parameters.
