Yes you would.  Throw out the Coldfusion/PHP/Perl and embrace Java Server
Pages/Servlets/and EJB's.

If you still want the authentication server-to-server, then you need an
XML-RPC architecture.  This doesn't solve the problems of Global user
sessions.... :)

Ok, here's my understanding of J2EE in a nutshell. I'm not going to talk
about .NET because I know that it's just basically the same thing as J2EE
but written VB style with a Hailstorm/User authentication/authorization

(Really Sun ONE and .NET are competeing products who's underlying
technologies are J2EE and C#/Biztalk/IIS/ASP...)

Basically J2EE is a EJB (Enterprise Java Bean) Server Container.  This
Container is a logical construct that can reside over several physical
server/load balancers/etc.  Within this Container, you've got Session
Beans.  These constructs are responsible for maintaining "states" across the
Container architecture.  Sessions can be of all different classes but
basically we're talking about User Sessions spanning the entire
architecture.  I believe that Resources (Database connections/MQSeries
connections/etc) also utilize the Session Beans for their purposes...

I believe that you can have inter-architecture operability, i.e. ColdFusion
to J2EE, using IIOP or CORBA...  It's ugly, but I believe that it is

IMHO, J2EE works great when you have "clients" that are really humans
accessing data through web-applications who get data from a multitude of
sources...  When your "clients" become Autonomous agents, then the model
will still work, but you get into these hybrid J2EE "app-servers" that are
sold by CommerceOne, BlueStone(now HP), RosetteNet, etc...

JBoss is really the only Open Source project that is attempting a to have
J2EE functionality but not necessarily J2EE certification.  This is the same
fine line that Mesa walks... It's OpenGL compliant, but not certified...

I'm pretty sure that's essentially how the J2EE works.. To the best of my
knowledge, anyway......  <sarcasm> n e 1 want to change from CF to Java???
