- Implement business logic with the Drools rules engine - The author used Drools rule engine to demonstrate how business logic could be externalized in an application and possibly maintained by end users. Rules are stored in xml format and loaded into a rule engine at runtime. A rule is composed of 3 parts, parameter, condition and consequence. Parameters are passed in by the engine. If condition is met, then the instructions in consequence are executed. The instructions are defined in java language.
- Getting Started With the Java Rule Engine API (JSR 94): Toward Rule-Based Applications - Java Rule Engine API is composed of rules administrator API and runtime client API. Users call the administrator API to register and unregister RuleExecutionSet and call client API to apply the RuleExecutionSet. Several open source rule engines were mentioned in the article as well, including Jess, Drools, FairIssac Blaze Advisor, ILog JRules, etc.
