THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
this code sample were taken from
specialpurpose/googlecheckout//script/org/ofbiz/googleCheckout/PrepareXMLTemplate.xml
it is a good example of how to extend simple-methods using java scripting.
though dated this is a source also
http://ofbiz.apache.org/docs/minilang.html#MethodExample
Handy Hint
You may get errors because of xsd differences, refer to
Using locale XSD files
the Scripting using Java is accomplished using Beanshell (bsh) or Groovy (script)
both can use standard java, but each can use the unique scripting for that script.
Warning
Note: work in progress feel free to add you examples.
