Hey Tom,
No, there is no such thing yet. However, it can be done easily. The
biggest problem is that - in order to complete the meta model to
generate code from - QDox needs access to all class definitions used
in your application context. That means that you need some sort of way
to identify those jar files in Ant. I happen to know that the folks
from J2ME Polish were considering adding Ant support. You might want
to contact them to see if they have something cooking.
