Complementando, segue um detalhe sobre o uso do exec()..

The reason this doesn't work is that "dir" is a builtin command of
command.com (or cmd.exe). Runtime.exec() starts a process rather than
executing a command in a command shell. Therefore "dir" and similar
commands will not work. If you want to do this sort of thing, you might
want to create a batch file and exec the batch file instead, or just use
the standard java.io.File stuff for listing the contents of directories.
Se voc� vai utilizar com o ls do Unix, n�o h� problemas (pra dizer a verdade
n�o tirei a prova :-D)... s� tenha em mente que esta n�o � a maneira mais
"elegante" de se conseguir os arquivos de um diret�rio.. :-)
