[http-jetty] user report

[David Worms]

Just got my web application running under the new jetty component. For 
this, I had to make a few twists. First, I did not experience the same 
problem as Stephen did (ClassCastException). Here is my environment:

  Version: Merlin SMP 3.0
  Build: 20031115
  Environment: Mac OS X 10.2.8 Java 1.4.1_01
The problems I had where in the JettyWebServer implementation. The 
service resolution is made with the full class name. I updated it to 
use the key "session-manager" which point to my own implementation of 
SessionManager (which extends AvalonSessionManager). From there, 
everything work. Attach a sample of what I did:

I also add the debug and admin servlet provided by Jetty for 
development purposes:

            <Context name="admin" path="/">
                <Servlet name="Admin" path="/" 
classname="org.mortbay.servlet.AdminServlet"/>
                <Servlet name="Debug" path="/Debug/" 
classname="org.mortbay.servlet.Debug"/>
            </Context>

Note, there seems to be a problem with the resolution of absolute web 
context path. something line "/myWebApp" will be resolve as 
"${jetty.component.home}/myWebApp"

I'll be happy to work on a simple Maverick based demo app and some test 
cases. Stephen mentioned some potential changes, so i'll wait until the 
component api is fairly stable.
