16.10. Creating a Rule Set

Ensure the rule-set imports the ESB message. To test, use this code:

import org.jboss.soa.esb.message.Message

import org.jboss.soa.esb.message.Message

Next, ensure the rule set defines the following global variable which creates the list of destinations:

global java.util.List destinations;

global java.util.List destinations;

The message is now sent to the JBoss Rules engine's working memory.

Now you can turn a regular rule set into one that can be used for content-based routing. Do this by evaluating the ESB message's matching rule and ensuring it outputs a list of service destination names.
