I did manage to finally get the example to run using eclipse, but still don't
know why ant doesn't like me.
To get it to work with eclipse, I added all of the external jar dependencies,
and setup a run configuration that passed in the proper args. The jvm needs -D
arg to set a 'PROJECT_ROOT' system property that is expected by the example
code.
Minor Bug? When the examples.xml is not found, because the system property is
not set stack, the parse
method throws a runtime exception. The catch tries to create a more
informative exception, but it assumes the file loaded, and the locator gets a
null exception. See stack:

Subject: RE: difficulties with example
I had already done this. But for kicks, I did it again. From the hivemind
root, I ran "ant install" this built the project and ran numerous unit tests
successfully.
When I cd down to examples and invoke ant run-calculator.
run-calculator:
