perhaps the JVM running ANT is also locking the JAR

hmmmm ...

That jar IS in my classpath, but the "clean" target I'm running doesn't
call javac or anything else that would use the classpath.  Besides, I
waited for hours (while doing other stuff, of course !!), and tried
running the "clean" target again, and I still get the same problem.  The
weblogic server is not running.  NOTHING is using that jar.  So I really
don't get it ...

help ..... ( i really don't want to manual delete that jar from explorer
everytime )

This is fairly common. Is there anywhere in ant file that you *use* the
? (ie in <classpath> of a java task or like). If so it is likely that
task is locking the jar. SO when you try to delete it, it fails but as
as ant finishes, the jar is unlocked. Thus in the second pass you can
delete the jar (or can delete it from explorer interface).
