RE: [rules-users] Exception error when using RuleAgent

Hi Rod, I had a similar error and I solved it by upgrading to Drools 4.0.3 on the BRMS and for the RuleAgent. See Jira: http://jira.jboss.com/jira/browse/JBRULES-1245 Hope this helps, Len -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of kissro(a)lidp.com Sent: Friday, November 16, 2007 1:23 PM To: rules-users(a)lists.jboss.org Subject: [rules-users] Exception error when using RuleAgent Hello, I created a rule in BRMS and downloaded the package to a directory. I'm using RuleAgent to load the RuleBase using the following code: RuleAgent agent = RuleAgent.newRuleAgent("/brmsunderwritingrules.properties"); RuleBase ruleBase = agent.getRuleBase(); I'm getting the following errors. Could someone tell me what I'm doing wrong and/or how to fix this please.
