Hi All Adance thanks,Can some please help me i'm trying to load drl files when i start my program or if any change occured in drl file need to load drl files into rulebase. private RuleBase loadRules() throws Exception { Reader source = null; PackageBuilder builder = new PackageBuilder(); Package pkg = null; RuleBase ruleBase = RuleBaseFactory.newRuleBase(); String path[] = rulesFile.split(","); builder = new PackageBuilder(); for (String filePath : path) { source = new InputStreamReader(RulesEngineDoerLinkWithQuery3jmx.class .getResourceAsStream(filePath)); builder.addPackageFromDrl(source); } pkg = builder.getPackage(); ruleBase.addPackage(pkg); return ruleBase; } i'm doing that and using with new rulebase creating new statefullSession, after adding new rule when program is running calling the loadRules() method So it returns new ruleBase. When i print ruleNames,its not priting the new rulename. Note:could have doubt for any one i may not calling loadRules() when i change in drl file,its calling i checked using break point in debug mode. Rule rules[] = ruleBase.getPackage("rulesrules").getRules(); for(int i = 0; i <rules.length; i++) System.out.println("*****"+rules[i].getName()); StatefulSession workingMemory = ruleBase.newStatefulSession(); .............. Inserting objects............ ..... workingMemory.fireAllRules(); if (workingMemory != null) { workingMemory.dispose(); workingMemory = null; } I'm using rules 4.0.1.

I made a mistake in my previous message. The LHS is the "when" part of the rule. Also, it appears you may have misunderstood the syntax of the LHS where something like X( z == y ) is not a call to a function, but a question of fact to be interpreted as "there is an instance of class X with field z equal to the value y".

ok thanks ... i solved my problem using eval(statoNodo.variabiliInOR("$param")); the function variabiliInOR returns a boolean variable Regards Raffo 2007/9/21, Scott Reed <sreed(a)spamcop.net&gt;:
