Hi Yogesh,
You might want to check the JEP project at http://www.singularsys.com/jep/
. I haven t used it but I know projects using this for an
*apparently* similar problem.
Hope this helps

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.
Thanks,
Yogesh
