Hello all, This question is not related to AppFuse so please pardon me, but since there are so many developers from open source community here, just thought of getting some opinions. We have a business requirement in which the end users would create mathematical "formulae" through a UI. So in a single transaction, a user could create a formula, apply it on the transactional data, and save the formula for future use. The operands in a formula would be attributes of certain objects, and the operators could potentially go beyond just simple algebraic operators. An example could look like this:
if (object.country == "USA") then output = (object.normalRate * (@someConstant + #someUserInput)) / object.quantity else output = (object.exciseRate * @someConstant) / object.quantity The "decision-making" behavior of the formula inclines me towards using some rules engine like JBoss Rules/Drools. Does anyone here know if JBoss Rules or any other rules engine would fit for a requirement like this, where rules could be created dynamically through a UI and then saved (file or database) or users could select a rule among several available ones? I would really appreciate any feedback.
