JBI Support deprecated in Apache ServiceMix 4
JBI 1.0 support is available in Apache ServiceMix 4 to allow existing users to migrate more easily to this latest version - if you're a new user, you should consider JBI deprecated and not use it for your project. Take a look at our technology selection guidelines for more information.
servicemix-drools
Overview
The ServiceMix Drools component provides JBI integration to the Drools Rules Engine.
This Service Engine can be used to deploy a rules set that will implement a router or an actual service.
A router will mostly act as a transparent proxy between the consumer and the target service provider mad will mostly be implemented by the jbi.route(uri) method below. This method creates a new exchange identical to the one received by the component and will send it to the specified destination. You can also send back a Fault if needed. A router can also be implemented by using directly the JBI Apis (available with the jbi helper) by using the provided client.
Namespace and xbean.xml
The namespace URI for the servicemix-bean JBI component is http://servicemix.apache.org/drools/1.0. This is an example of an xbean.xml file with a namespace definition with prefix bean.
<beans xmlns:drools="http://servicemix.apache.org/drools/1.0">
<!-- add drools:endpoint definitions here -->
</beans>
Endpoint types
The servicemix-drools component defines one endpoint type:
