always recompiles
Okay, I read that a directory structure that does not match the package name
will cause re-compiles. Are there other reasons?
Can anyway tell me what my incorrect assumptions were, or at any rate, how I
can get this thing to quit compiling every time?
Here is my package name:
jp.gr.alpsgiken.myclass.dbdriver
And here is the directory structure:
WEB-INF\src\jp\gr\alpsgiken\myclass\dbdriver
WEB-INF\classes\jp\gr\alpsgiken\myclass\dbdriver
and here is my build.xml, which I am keeping in WEB-INF:
<?xml version="1.0" encoding="Shift_JIS" ?>
<project name="myproject" default="dbdriver" basedir="src">
<property name="src" value="."/>
<property name="build" value="../classes"/>
<property name="dbdriver_loc" value="jp/gr/alpsgiken/myclass/dbdriver"/>
<target name="init">
<!-- タイムスタンプの生成 -->
<tstamp/>
<!-- samples のコンパイルに必要なディレクトリ -->
<mkdir dir="${build}/${dbdriver_loc}"/>
</target>
<target name="dbdriver" depends="init">
<javac
srcdir="${src}/${dbdriver_loc}"
destdir="${build}"
debug="on"/>
</target>
</project>

Ant now knows that you want the properties to point to files and that
it should resolve the file names relative to the project's basedir.
The values of the properties will be absolute pathnames.

Not sure what you mean by location instead of value, but here's what I did:
<?xml version="1.0" encoding="Shift_JIS" ?>
<project name="My_project" default="rest" basedir="src">
<!-- set global properties for this build -->
<property name="src" value="."/>
<property name="build" value="../classes"/>
<property name="dbdriver" value="jp/gr/alpsgiken/myclass/dbdriver"/>
<target name="init">
<!-- ?????????? -->
<tstamp/>
<!-- ??????????????? -->
<mkdir dir="${build}/${dbdriver}"/>
</target>
<target name="dbdriver" depends="init">
<!-- dbdriver ???????????? ${build} ?????????? -->
<javac destdir="${build}" debug="on">
<src path="${src}"/>
<include name="${dbdriver}/*.java"/>
</javac>
</target>
<target name="rest" depends="dbdriver">
<!-- ??????????????? ${build} ?????????? -->
<javac destdir="${build}" debug="on">
<src path="${src}"/>
<exclude name="${dbdriver}/**"/>
</javac>
</target>
</project>
dbdriver is "package jp.gr.alpsgiken.myclass.dbdriver". I'm in the process
of modularizing the code, and the dbdriver class was the first package to
fall out. This keeps the dependencies straight, and does not cause
unnecessary recompiling. The rest of the packages will fall out in a similar
way.
The exclude element/property was relatively intuitive to me, but include was
a little counter-intuitive, until I caught onto src/srcdir being directories
rather than files. I guess that's what you mean by location instead of
value.
Thanks, and sorry for the noise.

I'd highly recommend location instead of value here.

srcdir should be the top of the source tree, which is ${src} in your
case.

Never mind. I found what I had overlooked in the docs. I was misinterpreting
the meaning of the includes property for the javac element. (I hope.)

Use srcdir="${src}" instead.
