This is a common problem that we all face.
It has been discussed ad nauseum in the forum so I wrote these articles.
I hope that they help.

@Doug What you said is exactly what I'm talking about. I WANT to externalize my
configuration, and am almost set up to have it
completely external. My problem has been figuring out how to get the external
properties back into the WAR. For this, I'll check
how powerful these overlays that Matt mentioned are.
The thing is that you shouldn't get the config file (e.g. a properties
file) back into the war. Instead, your code should read the config
file from the classpath and then you just need to have the config file
available on the classpath in runtime. This is supported by app
servers etc by having this file in a config folder external to the
deployables.
A similar solution is to read the configurations from JNDI. Similar in
that sense that it is external to your deployable archive.

I DON'T want to couple database credentials etc. with my source code. I would
only put a template properties file in the source, with directions for
deployment.
One idea is to have my xml files try to be more dynamic. For example I could
guide the configuration at runtime based on environment variables(I saw this
idea on-line somewhere). Environment variables are usually available as xml
properties. I could throw my external properties files into the
$CATALINA_BASE/lib directory and point to different files as I need them at
runtime. Does this sound reasonable to everyone?
Thanks for all the ideas.

I would like to be able to modify the contents of a WAR file.
Goal: I would like to be in a directory with my WAR and a pom.xml. When I type
'maven configure', I would like maven to apply a filter to some of the files in
the war, and then leave behind the exact same WAR, with the filters applied. I
don't need to compile any files, I just need to apply some filters to some
files that are already in a WAR.
The motivation for this is that I compile something that is still
un-configured. I throw the war into my test environment and configure it. If it
passes, I graduate it to production and re-configure it.
Note: I don't care whether or not I use Maven or something like a scripting
language to accomplish this. The end goal is what I described above, one typed
command that reconfigures the WAR. I thought Maven might be able to do most of
the leg-work for me.
Any help is appreciated, thanks.

Maven is not a scripting tool.
It has very definite ideas about how software gets built and this is not
really in line with its ideas.
In dealing with Maven, you have to conform to its process or you will
have a miserable life until you submit.
"Resistance is futile" is your best mantra when planning to do battle
with Maven.
Stop before you start.
Try Ant.
It is the Border Collie of Java tools and wants to do whatever you want
to do.
It has no preconceived ideas about "Best Practices".
