Aaron,

Configuration is generally pretty static and XML just provides a better
way of adding structure.  However, performance can be very good. It all
depends on your priorities. A couple of lines of Java code with JDOM can
build a configuration object that runs anywhere with little change
because it can rely on APIS that are part of any 1.4+ JDK. If
performance is a priority, I might opt for a configuration object that
implements a SAX interface, for example to configure how an individual
email is sent. This last case wouldn't be as simple and requires setting
environment variables to identify the SAX implementation.

Storing config info in XML for Java is peaking my interest here.  I
have
been using xml config files for other packages for some time (i.e.
Tomcat) but haven't built it into any of my home grown programming. 
Are
these performance efficient enough being that you have to parse the
data?  How often do you parse the config?  Once per HTTPSession/AS400
job?
