Embedding Pluto (again)

Hi,

I've created and maintain a few web sites, and I'm looking at Pluto to 
make developing the sites quicker and easier. At first I'd just like to 
embed the container in the simplest way possible, but over time I'm 
considering building up the portal side, much simpler than Jetspeed, and 
tailored to my requirements.

I've got all the supplied wars installed and working, and have deployed 
my test portlets, and am now starting to embed Pluto in my own project, 
using David's documents as a guide. I currently have all the Spring 
stuff in, including the Listeners and Servlets. So far so good(ish).

I'd like to know what the absolute minimum is for getting a portlet into 
my site is. I was hoping that I could just use the Pluto taglib and 
supply the context and portlet as params, but it looks a little more 
complicated than that. Do all request need to be routed through the 
PortalDriverServlet for example?

I appreciate this has been asked on this list before, but I haven't 
found a step-by-step guide for complete beginners to just get a portlet 
into an existing application in the simplest way possible, preferably 
just using taglibs.

Many thanks in advance,
Digby
