THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
this code sample were taken from
http://svn.apache.org/viewvc?view=revision&revision=584440
see
https://cwiki.apache.org/confluence/display/OFBIZ/Google+Checkout+Integration
it has since been removed from the svn.
I like chris's work because it is a good example of how to extend simple-methods using java scripting (BSH).
though dated this is a source also
http://ofbiz.apache.org/docs/minilang.html#MethodExample
I am showing how to use Groovy to accomplish the same processes mostly as examples.
Note: work in progress feel free to add you examples.
