Raphael Lute: thank you very much for your tremendously helpful and
informative answers!

So..

While reading the document for the IBM WebSphere Portal v.4.1, I run into
something that I do not understand, and thought that maybe you (or someone
else here) may be able to answer:

On page 7, a Porlet is shown like an extension of PortletAdapter, which is
an extension of Portlet. I guess the latter one is meant to shown
"implements". Nevertheless, these are both from package
org.apache.jetspeed.portlet. OK. But what I do not understand, is the logic
with the next step, where Porlet inherits from
_javax.servlet.http.HttpServlet_.

Has the Jetspeed API, old or new, _ever_ had any inheritance from the
servlet specification?

Is the Jetspeed API shown in this document actually available from the
Jetspeed CVS?

This inheritance scares me! This, to me, seems like a TOTAL trashing of the
concept of a "loadable module" or "portal application" that I've found it
called here at Jetspeed. You're supposed to package the portal application
in a .war file. How are you supposed to have multiple portal applications
installed, then? Install multiple _web_ applications? But how is the
communication between the different portal applications supposed to be made?
For example, a HttpSession should not be migrated between different web
applications, according to the Servlet specs.

Given that IBM somewhat ambiguously states "The Portlet API offered in
WebSphere Portal Version 4.1 is the first step toward the Portlet API
standardization." (pg 6), I wonder about this Servlet dependency.

Jason van Zyl and David Sean Taylor: hi! Do you folks have any inside info
you can share?! ;)

Thanks,
Endre.
