I also have build-order issues (it makes me feel a whole lot better to
finally find someone else who does :)  I have separate <javac> tasks, and
in the order the compiles should happen. One thing you have that's not
right is specifying the full package-path in "srcdir" -- <javac> doesn't
like that. You need to specify "srcdir" as the path leading up to where
the COM/pkg/etc. starts, then include the COM/pkg/etc. as part of the
filenames of the files you want this <javac> task to compile:

  <include name="com/hcl/dal/"/>

But note -- there's no way I know of to prevent side-effect compiles (eg.,
I have a <javac> task that lists 2 source-files, but it ends up with 750
classfiles having been compiled, since Java compilers go build what they
need when they need it).
