This is a just a Drools example. Basic example:
teapot rule.
If error code is 418 and message is 'tea'. You can change the rules on
rule admin page.
- when ERROR_code=200 then result.message='OK'
- when ERROR_code=418 AND message='tea' then result.message='Tea time'
- when ERROR_code=404 then result.message='Not found'
- Any other case rule won't run, and basic message will be UNKNOW
