Easy Rules is a simple yet powerful Java rules engine providing the following features:

* Lightweight framework and easy to learn API
* POJO based development
* Useful abstractions to define business rules and apply them easily
* The ability to create composite rules from primitive ones
* Dynamic rule configuration at runtime using JMX

In a very interesting <a href="http://martinfowler.com/bliki/RulesEngine.html" target="_blank">article</a> about rules engines, <a href="http://martinfowler.com/" target="_blank">Martin Fowler</a> says:

>You can build a simple rules engine yourself. All you need is to create a bunch of objects with conditions and actions, store them in a collection, and run through them to evaluate the conditions and execute the actions.

This is exactly what Easy Rules does, with more features like rule composition and dynamic configuration.
