Give Your Business Logic a Framework with Drools (O'ReillyNet)

Paul Browne looks at Drools on O'Reilly. "It's almost too easy to express your business logic as a spaghetti-code fiasco. The result is hard to test, hard to maintain, and hard to update. Rule engines offer an alternative: express your business logic as rules, outside of your Java code, in a format even the business side of the office can understand. Paul Browne uses the open source Drools framework to introduce the idea."
