Hi Jeff,
Here are some notes that may help.
1. regarding the first question, what you have seen is in xml containing
calcop element ,
for ofbiz its called Minilang which you can call it an intermediate
programming language that you can use it to make small programming tasks
(business logic),
and later this XML element will be interpreted by Java code, and for
your information this MINIALNG will be deprecated as per the ofbiz
community and will be replaced by groovy scripts.
( 2. & 3 ) . regarding to the second and third question I know that you
seem to be very new to the OFBIZ like me , so take the time to read the
getting started for both developers and business users,
Here is a link
