Roolie

An extremely simple Java Rule Engine (Non-JSR 94) that uses rules you create in Java. Simply create your basic rules, implement the single "passes" method for each, then chain them together in an XML file to create more complex rules.

Features

Simple Java Rule Engine
Pure Java 6 - No Other Dependencies
Non-JSR 94 (This is a feature!)
Chain your rules together in an XML file to create complex rules
No learning curve - write your rules in Java and implement one method
Uses short-circuit AND/OR logic when evaluating rules for high-performance
Unlike JSR 94, order matters! Put simple rules toward the top to increase performance
Critical Note: OR-ing rules in a rule definition creates an implicit parenthesis around them
