Now its been a month that I'm tring JetSpeed2. Same as
you, it is not my recommendation to company manager,
but he is still insisting . . .

I completely agree with 'Ali Behzadian Nejad'. You
must be a JAVA SUPER EXPERT to write a simple hello
world portlet and should be a SUPER HERO to be able to
deploy it in a portal.

There are some documents over net which prefers 'exo'
and 'pluto'. But I myself suggest apache software,
because of its great integration, support, security,
performance and usability.

Arash, please let me know if you ever tried JetSpeed2.
Because I saw better review results from Jetspeed2
from other open source portal  Servers. Additionally,
JetSpeed2 is reference implementation of JSR168 and is
using standard open source software of Apache
(Velocity, Log4J, Pluto, ...). By all of this, if you
still thinks others are better, let me know to
migrate. It would be very much appreciated.

Just, please, review your requirements. If you
interested I could send you 100 links that recommend
using a simple JSP/Struts/MySQL approach instead of
dealing with Portlet/Portal/Servlet/Tomcat/Oracle
approach.

If you started using JetSpeed2, feel free to ask your
questions. I will help you if I could.
