javac `find . -name '*.java'`

What? You're using Windows? Oh, sorry to hear that.

Most people use Ant these days for building Java applications. It's fairly easy to use and it solves this particular problem easily. Once you set up an Ant build file for your project, it will save you a lot of typing.

Yes ANT is the best build tool available for JAVA. I use it all the time!
I'm on Windows XP Pro and the cmd shell is, well, not allways useful (to say the least).
But if you want to do things like javac `find . -name '*.java'`, you can also install Cygwin and have fun!

and unixutils are available without linux-emulator for windows too.

But if I understand correctly, your dirs are:

c:\java\a
c:\java\b
c:\java\c

If they belong to the same project, a 'javac b\MainClass.java' should work, if your package-declarations are in order.

c:
cd \java
dir ?\*.java > source.lst
; don't know whether 
; dir [abc]\*.java > source.lst 
; works on windows? And do you have d, e, f too?

I read something about a switch to compile all files, found listed in a file.

Yes - I found it again:
$JAVA_HOME/docs/tooldocs/tools.html#basic

go to your sysarchitecture, and find:
javac @argfile
which means in the example above:

javac @source.lst

Since javac without arguments shows some options, it's surprising, that there are additional options, not shown.

Since sun normally is very calculable, this is super-surprising.
