Directory set

[Marco Montel]

Like fileset i need a method to create a directory set. When i compile
with bmj, i need to pass him a list of packages to compile, that i can
obtain from the directory structure of my sourcefiles.

  <path id="sources">
    <fileset dir="${src.dir}">
      <include name="**/*.java"/>
    </fileset>
  </path>

  <property name="source.files"   refid="sources"/>

This give me a complete list of files *.java but i need a complete list
of all subdirs of ${src.dir}

How can I obtain it ?

bye Marco
