[Jetty-support] Trying to split my web application in two

[Howard M. L. S. <hls...@co...>]

I'm trying to do something a little unusual.  I'm retrofitting an =
existing application to use
Tapestry, and I'm using Jetty for my debugging.

This site can be deployed with one of several "skins".

For testing purposes, I want to be able to run Jetty for my workspace as =
a web application (i.e.,
with WEB-INF and all that).  However, I want to map /skin within my =
context to another directory.
Mostly, this works correctly.

I've gotten this to partially work with this jetty.xml:

<?xml version=3D"1.0"  encoding=3D"ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure =
1.2//EN"
"http://jetty.mortbay.org/configure_1_2.dtd">
  =20
<Configure class=3D"org.mortbay.jetty.Server">
  <Call name=3D"addListener">
    <Arg>
      <New class=3D"org.mortbay.http.SocketListener">
        <Set name=3D"port">8080</Set>
      </New>
    </Arg>
  </Call>
 =20
   <Call name=3D"addWebApplication">
    <Arg>/skin</Arg>
    <Arg>web/context</Arg>
  </Call>
  =20
  <Call name=3D"addWebApplication">
    <Arg>/</Arg>
    <Arg>web/defaultskin<Arg>
  </Call>
 =20

</Configure>

In fact, from the browser, =
http://localhost:8080/skin/images/tab_about.gif (for example) works just
fine (the file live in my worksapce, under web/defaultskin/images).

I debugged this in my application, and got to the call to =
ServletContext.getResource().

I did some debugging, and got to the point where my code asks the =
ServletContext about the file.

_context.getResource("/skin/images/tab_about.gif") returns null

_context, in this case, is an instance of =
org.mortbay.jetty.servlet.ServletHandler$Context

I guess this makes sense, the file in question isn't inside the context =
its in a parallel context.
But that doesn't help me.

So, what I need to do is rearrainge this to "nest" the context for =
"/skin" inside my main web
application context.

I haven't been able to figure out the right incantation for this.  Any =
takers?

My work around for this is less than ideal:  copy the merged content of =
my main context directory
and the skin directory to form a new directory. I just don't want to =
have to run Ant after every
change of my files, so I'm trying to accomplish the same result =
virtually, at runtime.  Doesn't seem
unreasonable to me.
