(1) Sure, a simple execute() could do, as described in the tutorial, which I recommeded to readers. I wrote a simple task that has a parallel structure to the more complex Jing task, following the guidelines in the first six steps of "Writing Your Own Task". Are those guidelines incorrect or out of date? If so, this section of the Ant manual needs to be updated. (2) Ant is a nice tool, but I don't feel it is necessary to use it to build something as simple as Add.java -- one very small class with almost zero potential for continuous debugging or rebuilding. (3) As far as using .class files: How exactly do you do that? I tried it every which way from Tuesday with no luck. Show us! (I haven't paid any attention to Antlib yet. Thanks for pointing it out.)

  Using a class file seems to work just fine for me.
  Using the "Add.class" example you use, simply
  make sure your classpath contains the directory
  where Add.class lives. Before running ant, I
  set my class path to "blahblah;newtasks" (under
  windoze). newtasks is a subdirectory of my
  current directory. newtasks contains Add.class
  (which is in the newtasks package). Similarly,
  you can add the classpath to your taskdef line
  
<taskdef name="adder" classname="newtasks.Add"
classpath="newtasks"/>

  This was done using ant 1.5, and jdk 1.4
