Calling Ant from a Java Class

[Boris Debic]

Hi there, 

What would be the right way to call ant tasks from Java, instead of doing it
from shell or batch files.
I am thinking about adding a new class that would essentially be a copy of
Main.java but without the system.exit()'s. I was hoping to set it up in such
a way that we can catch build exceptions directly in a top level driver
class. 

Does anyone see any problems with this approach? Has anyone done something
similar?

Thanks.
