Re: [rules-users] ClassNotFound exception running brms example (newbie)
Hi, Are you using the latest brms build ? if the anwser is not, please download the latest version from https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/it was a missing class in the drools-core library.

sorry, you need to get the latest core version snapshot to correct this problem, plus the new brms as well On 9/30/07, Fernando Meyer [EMAIL PROTECTED] wrote: Hi, Are you using the latest brms build ? if the anwser is not, please download the latest version from https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/ it was a missing class in the drools-core library.

[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.
