If you really want to access out and err, XmlLogger wouldn't be the
right thing to use anyway - it simply ignores whatever is send
there. It doesn't even get a chance to handle that.

If - on the other hand - XmlLogger would be fine but the XML is too
much for you, it should be quite simple to write a Listener that
writes all events to a file whose name has been generated from
properties, just like XmlLogger does.

And whose name has been generated from some properties. Without this
additional constraint, -logfile would be the solution. With this
constraint the answer is you can't. The main problem is that some
events will be generated before any properties have been set.
