It's very simple to set up my makefile for most projects.

I haven't seen Stephano's work. I'm trying to support multiple
compilers (not VMs - this isn't a runtime tool).

Basically what I'm trying to do is write macros that look like the C
ones, eg:

AC_PROG_JAVA_CC
AC_PROG_JAVA_JAR
AC_PROG_JAVA_DOC
AC_JAVA_CLASSPATH(class, iftrue, iffalse, path)
AC_JAVA_EXTDIR(jarfile, iftrue, iffalse, extpath)

I gather it will get easier to add these to autoconf as new versions
become popular. However, right now it's pretty easy to put these
into aclocal.m4 in every java project.

Yes. But not everyone wants that. I have a ton of class libs
installed in /usr/local/share/java. I generate my classpath from them
(see below the signature, it's a really cool way to get an extdir)
and just use the command line tool.

Some people I know use Linux features to automatically call the vm
when the command line sees the class file magic number, giving class
files the same status as perl or tcl.

I don't disagree with the shell script, but it is only one part of
the whole solution.

PS 
Here's my extdir generator:

  CLASSPATH=`ls /usr/local/share/java/*.jar | tr [:space:] :`

Try it, it's pretty cool.
