My 2c...

Who's to say that Drools is not a good fit?

I see any Rules Engine as a means to externalise rules; whether they are maintained by Users or IT.

Of course the overhead of introducing another technology to an applications code-base needs to be balanced with many other factors: skillset, memory consumption etc even frequency of change.

If the application in question is pretty static in its requirements for UI-centric rules; a good implementation of the Mediator pattern may prove more beneficial.

Cheers,

Mike

If the business logic is this simple then no, drools is not a good fit because business rules are not necessary.  The only thing that would make it necessary is if you had business users writing rules, but as far as I know drools 2.5 doesn't have much in the way of modern rules management. (unlike the 5.x series)
