The executeClass argument specifies the name of the existing class in which an existing method or script specified in the executeMethod, executeTypeMethod, or executeScript parameter is to be executed in the non‑GUI application specified in the app argument.
The default value is JadeScript. (See also the executeSchema and executeTransient arguments.)
Although this argument is optional with the executeScript argument, you must specify it when you specify the executeMethod or executeTypeMethod argument, or when you are running a JADE script in a subclass of the JadeScript class.
