Oops, that's not it, something else, my bad, sorry. Let me take another 
look,

Did you get all the jars I mentioned, looks like you don't have the

    Trying again without HiveMind.jar. So you will have to download
    HiveMind.jar also.

    I had to strip out the jars 'cause of the size and apache servers
    would n't let it go through, I kept the HiveMind jar though. So
    you would want to download the following jars to the lib folder.
    commons-beanutils-1.6.1.jar
    commons-collections-2.1.jar
    commons-lang-2.0.jar
    commons-logging-1.0.2.jar

Does anyone have a good example application (very simple, please) for
HiveMind?
Unzip the attached zip to a folder and run target "run". Its a very 
simple Calculator service pretty much the same that would find on 
the website with two functions/services - add and subtract!

 I would like to start using it and I just need a little nudge to
get me going.  Like, how do I obtain a handle to a Registry object 
in the
first place to set it as the default?  And, how many of these 
hivemind.xml
files am I going to have to have floating around?

As many as you want. You can in fact bundle up everything in one 
mumbo module if you like!

 It appears as if I need
one for each package in my project, but only one can be in my jar file
located at /META-INF/hivemind.xml?  Is this true?
No, you need one hivemodule.xml per module and a module can be 
anything you want like I said before.

 If so, packaging an
application could turn out to be rather tedious if I do indeed plan to
separate things out into these small, testable modules.  I may be
misunderstanding the documentation, though.  Anyway, if anyone has 
a good
starter application (maybe even with the entire project set up with 
an Ant
build script), I would be very appreciative.  I sure wish I would 
have known
about hivemind before.  It looks as if it does everything (and 
more) that my
little "business object factory" framework
(http://www.javaworld.com/javaworld/jw-07-2003/jw-0718-factory.html) 
does.
