"Future" as in "now" (available in tonight's nightly v2 build). :)
Alternate docroots of a webapp are configured as properties in
sun-web.xml, using the same syntax as the virtual server properties
used for configuring alternate docroots for virtual servers.
I've attached the sun-web.xml of an imaginary webapp "myapp" deployed
at
http://<host>:<port>/myapp, which specifies exact, extension, and
path prefix URI patterns for the webapp's alternate docroots.
The exact matching pattern will map
http://<host>:<port>/myapp/my.jpg
to
/svr/images/jpg/my.jpg
while the extension and path prefix pattern will cause any requests of
the form:
http://<host>:<port>/myapp/*.jpg
and
http://<host>:<port>/myapp/jpg/*
respectively, to be served from this directory:
/svr/images/jpg
For example,
http://<host>:<port>/myapp/abc/def/my.jpg
will be mapped to:
/srv/images/jpg/abc/def/my.jpg
I am going to post a blog with more detailed info, but thought you
might be interested to learn about this feature sooner.
