Orion Friendly E-Commerce Components

[xbill]

Hi-

I am looking for basic E-Commerce components
that run well under Orion.

I am looking for something like a light
version weblogic's commerce suite- but just
the basics- login, shopping cart, etc.

Has anyone had any success with any
third party packages - either
packaged as EJBS or JSP/Servlets running
under Orion?

thanks,
