I have created a .drl file that contains the following rule: rule "Underwriting Rule 1" dialect "mvel" when p : Policy( premium < "50.00" ) then p.setStatus( 32 ); end
The code below processes the rule: public void main(Policy inputPolicy) throws Exception { RuleBase ruleBase = buildPackage(); StatefulSession session = ruleBase.newStatefulSession(); session.insert(inputPolicy); session.fireAllRules(); } private RuleBase buildPackage () throws IOException, Exception { final PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl( new InputStreamReader( UnderwritingRule.class.getResourceAsStream( "/underwriting.drl" ) ) ); final RuleBase ruleBase = RuleBaseFactory.newRuleBase(); ruleBase.addPackage( builder.getPackage() ); return ruleBase; } The code and rule above process just fine, without any errors. Using the BRMS web interface, I've created a rule and compiled it into a package. The rule created via BRMS looks like this: rule "Underwriting Rule 1" dialect "mvel" when p : Policy( premium < "50.00" ) then p.setStatus( 32 ); end I've deployed the rule package and the code below processes it: public void main(Policy inputPolicy) throws Exception { RuleBase ruleBase = loadRuleBase(); StatefulSession session = ruleBase.newStatefulSession(); session.insert(inputPolicy); session.fireAllRules(); } private RuleBase loadRuleBase() throws IOException, Exception { RuleAgent.newRuleAgent("/brmsunderwritingrules.properties"); RuleBase ruleBase = agent.getRuleBase(); return ruleBase; } Now, when I run the above code, I get an error - ERROR [STDERR] RuleAgent(default) INFO Configuring with newInstance=true, secondsToRefresh=30 ERROR [STDERR] RuleAgent(default) INFO Configuring package provider : DirectoryScanner scanning dir: \deployed\rules found 1 file(s). INFO [STDOUT] Error - java.lang.ClassCastException: java.util.HashSet In the 2nd sample of code, I'm using a rule package and am using the RuleAgent to load the rule base but I don't know why I getting the java.lang.ClassCastException error. Does anyone know why? Rod _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
