[rules-users] executing specific rules using agenda group

Hi I am using Drools 4.0. First time I want to fire some specific rules from my rule file(in .xml format) and then other rules for the second time. I have defined agenda-group attribute for the rules as follows: <rule-attribute name="agenda-group" value="Check-rfq"/> how can I execute specific rules using agenda group or is there any other options are available. When I had gone through Drools documentation ,they mentioned Listener api can be used to execute specific rules but I did not find enough information on Listener. Please let me know how can I implement Listener api to execute specific rules.
