Re: JSP precompilation and including webinc.xml in web.xml
Al, If it's of any use at this point, your setup should work under 4.1. I did something very similar that worked with 4.1.8.

I got the complete precompilation process to work, but I gave up on trying to
reference the include file with an entity reference. It just doesn't work.
What I was able to do was write an XSLT stylesheet that takes the main
web.xml and the generated include file and generates a new web.xml that
incorporates both files. It uses the Ant style task to do the
transformation.
A slight wrinkle is that the generated include file is not a fully
well-formed XML file, in that it doesn't have a root element. So, in order
for the XML parser (used by Ant) to grok it, I had to write a simple
well-formed wrapper that references the include file with an entity reference.
It's ironic that I'm using the same mechanism in this process that I gave up
with using inside of Tomcat.
I'll show all the pieces of my solution here.
This is the excerpt from my build-war Ant target related to this:
-

Following this is the includeWrapper.xml file, which references the generated
include file. Note that I have to reference a path of web-inf/webinc.xml,
which is the path to the generated file in my build tree (not my deploy tree).
I'm using Ant 1.4. In Ant 1.5.1, there is apparently some new features in the
style task that allow the specification of an alternate EntityResolver that
would allow me to avoid hardcoding the name of the directory the file is in.

And finally, here is the stylesheet (webmerge.xsl) that does the
transformation:
-
?xml version=1.0?
xsl:stylesheet

elements of the main file, then the servlet-mapping elements of the
include file, then the servlet-mapping elements of the main file, and
then all the remaining elements of the main file (which will be
specified explicitly by element type.
