Chapter 17. The Java Rule Engine Application Programming Interface

JSR94 is an API used in JBoss Rules. It allows for support of multiple rule engines from a single API. JSR94 does not deal in any way with the rule language itself.

The JSR94 standard represents the "least common denominator" in features across rule engines. This means that there is less functionality in the JSR94 API than in the standard Knowledge API. By using JSR94, you cannot use all the capabilities of JBoss Rules. You should use globals and support for DRL, DSL and XML, via property maps in conjunction with JSR94. This introduces non-portable functionality.
