This project is currently has Incubator status.
Business Rules Service Engine (a.k.a "rules4jbi") is a JBI (JSR 208) compliant service engine that allows to integrate a JSR 94 compliant rules engine into a JBI container and expose a deployed ruleset as a stateless service within the JBI environment. The accompanied NetBeans plugins allow for easy creation of the deployment artifacts and integrate well with the rest of the NetBeans SOA/enterprise pack.

Rules4JBI is not a rules engine by itself and does not ship with any bundled rules engine either. Therefore, for proper operation, it requires you to install/deploy your chosen JSR 94 compliant rules engine. First, please consult your rules engine vendor's documentation to determine which jar files you need. Then, you have two options how to install/use the rules engine:
# you can copy the jar files into your GlassFish domain's {{lib/ext}} folder. This way, the rules engine will be available for all service units deployed into the service engine. This is a convenient way to install the rules engine, best suitable for testing purposes. Don't forget to restart GlassFish if it is already running as this mechanism does not support hot deployment.
# you can deploy the rules engine's jars along with the service unit. This will allow you to use different versions of the rules engine for different deployments.
At line 42 added 1 line.
Note that you are free to combine these two approaches, e.g. you can install one version into the {{lib/ext}} folder and then deploy a different version as part of your service unit. The version bundled with the service unit will take precedence. And obviously, nothing prevents you from using different rules engines for different service units.

!!!Inside Rules4JBI
!Project Architecture
For a diagram illustrating this project see __[Architecture|Rules4JBI.Architecture]__.
As of December 2008, we do not officially support or endorse any rules engine. However, the project is tested to work with [Jess|] (the JSR 94 reference implementation), [Jamocha|] (a CLIPS-based rules engine like Jess, but Open Source), and [Drools|] (a.k.a JBoss Rules). We encourage other vendors of JSR 94 compliant rules engines to test their implementations against this component and report the results/problems to the users mailing list at [OpenESB mailing lists|].

The source code for the Rules4JBI project is located under [Open JBI Components CVS|]. The source is located under the [<partner/project folder>|<partner/project folder>] directory.
!!Getting Started
At line 48 added 49 lines.
Watch the screencast (coming soon) to see rules4jbi in action.
!Quick Start Guide
The [Quick Start Guide|Rules4JBI.QuickStartGuide] contains a step-by-step explanations of what you have seen in the screencast.
!Sample Project
'''' contains the JSR 94 TCK example with Drools we have created in the Quick Start Guide. Contrary to that example, this sample project bundles Drools rules engine within the service unit, for easy, out-of-the-box experience. Please see the enclosed {{LICENSE.txt}} file for the license of Drools and its dependencies.
Steps to Use:
# The sample project's zip file contains Rules Module project and a Composite Application project. Extract the zip file and open both projects in NetBeans
# Build and deploy the Composite Application project
# Run the TestCase included in the Composite Application project
