Java Rule engines
Greetings! Recently I've been working on a piece of software that will require a rule engine to implement dynamically changing business logic.
I've read a bunch about a number of different open source projects currently out there including JBoss/Drools/Java scripting engines recently added to the JDK/ etc.
I'm pretty much set on using one of two methods:
Java Scripting engine
The problem I'm having with Drools is actually getting it setup to accept an xml file with the associated rules. I've read the articles on IBM and several other tutorials but I can't get my head around exactly what objects need to be instantiated to get the engine itself up and running. I sort of understand the WorkingMemory objects but beyond that I"m lost. I've read through the API, but I"m still at that point where I think I know I lot about java but still aren't quite comfortable sifting through the api to find what I'm looking for.
Anyway, I've been over the below link in particular a 100 times. I could use some insight into how to go about setting up this particular rule engine. It's kicking my butt.
Implement business logic with the Drools rules engine
As for using a Java scripting rule engine, I've read through the below link and I feel pretty comfortable implementing this rule engine, but here's the rub:
Scripting for the Java Platform
I know it's a lot but any thoughts/suggestions would be immensely appreciated. Thanks a bunch!
