16.10. Creating a Rule Set

  1. Ensure the rule-set imports the ESB message. To test, use this code:
    import org.jboss.soa.esb.message.Message
    
  2. Next, ensure the rule set defines the following global variable which creates the list of 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.
