Where does portlet run

[Xianfeng Yuan <xi...@speakeasy.net>]

Hi,
I am new to jetspeed and portlet. Our company just start a project to build
a portal for customer. I am looking at jetspeed.

My question is where portlet run? From documentation, portlet should run
under portletcontrol, which run under portletcontroller. I think
portletcontroller is jetspeed in this case. But from my knowledge, each
individual web application should run under their own server. Like from MSN
you can go to EXPEDIA. But EXPEDIA is running on its own server, MSN just
work as a container whic hold EXPEDIA. But if I write a Portlication. It run
under jetspeed portal server, not on its own server. This confuse me a lot.

Thanks.
Stephen
