JRules offers support for user-defined rules templates for companies using multiple business rules that have common elements, such as those that might affect product volume discounts. This helps speed up the creation of business rules.

We also liked the rule-query facility. An included editor defines queries in Ilog's proprietary Business Query Language. We quickly searched the rules in our various projects on the basis of property values, class members, and class references.

Companies that build and implement Web services will find JRules well prepared to manage business rules for these types of deployments. The solution can access XML objects and define rules on XML data.

We found rules deployment using BEA WebLogic an easy affair. The JRules engine can be integrated into an Enterprise JavaBean (EJB). Users can also integrate the JRules engine, a stateless session bean, into one or more J2EE (Java 2 Platform, Enterprise Edition) applications.

Ilog JRules 4.0 is a solid solution that will help enterprises gain the upper hand on managing business rules in distributed application environments, thereby reducing costs. Its centralized repository, useful tools for business analysts and programmers, and easy insertion into varied application environments make it a good fit and well worth consideration.
