If you insert facts that have a chance to match, and if you enable genda-group "AndroGel" then I see no reason why it should not work. -W On 16/08/2012, Rana <ven12344(a)yahoo.com&gt; wrote:

How can I fire one rule file if I have lot of rule files defined in my change set. Right now I have written an if-else condition and checking if the input is Androgel then fire Angrogel rule fire.

How to use boolean variables in the rule.

You must not use this: eval( boolBrandName && boolProviderState && boolDrugStrength ) since changes in global variables are not visible to the Drools rule engine. But you don't need this eval(...) line, since you have rule "Brand Name" rule "Provider State" extends "Brand Name" rule "Drug Strength" extends "Provider State" rule "Check" extends "Drug Strength" and therefore "Check" will not fire unless "Drug Strength" fires; "Drug Strength" will not fire unless "Provider State" fires; "Provider State" will not fire unless "Brand Name" fires. -W On 17/08/2012, Rana <ven12344(a)yahoo.com&gt; wrote:

Hasn't this been answered only recently on this list? 1) For simple conditions, a rule negating the condition of your rule will fire if the other one fails: rule "a != b" when test( a != "b" ) then //consequence end 2) If you have rules extending each other, the first one not firing contains the condition(s) that are not fulfilled. 3) An individual analysis of the attributes of a fact can be done, collecting the conditions that are fulfilled. At the end of the analysis, you either have the situation that all required attributes are fulfilled (and you can execute the consequence) or not, and thus you know what's missing. -W On 17/08/2012, Rana <ven12344(a)yahoo.com&gt; wrote:

It's worth thinking about it differently. A rule does not fail. It just defines the conditions under which it will activate. If you wish to perform an action whether the condition is true or false, you have 2 options: A positive and a negative condition: when test(a == "b") then ... when test(a != "b") then … A condition which is always true: when test() then if (a.equals("b")) { ... } else { ... } To be honest whether you write 1 or 2 rules should not be a 'business' decision. Why does anybody think there should not be 2 rules? It's probably worth considering what you're trying to achieve. Does logging of a fact value really need to be part of a rule? For instance, if you're actually just looking for an audit trail, you can have a WorkingMemoryEventListener, which can listen for all of the fact insertions, updates and retractions. It can log them all as they happen. Combined with an AgendaEventListener, you can log what rules have activated and what the values of facts were at the time. Use an asynchronous logger and this will have very little impact on rules processing performance. Alternatively if the business are writing rules, and only wish to write the positive match, then maybe you can create a DSL which generates the both the positive and negative rules behind the scenes.

Yes I have that, but no luck. But again this should be dynamic so I am guessing I should write if-else stmts to focus on? ksession.getAgenda().getAgendaGroup( "AndroGel" ).setFocus(); * Logging is also not working in the rule file. Logger logger = Logger.getRootLogger(); ksession.setGlobal("log", logger); workingMemory = ksession; workingMemory.insert(logger); workingMemory.insert(drug); workingMemory.insert(address); workingMemory.insert(program); ( (StatefulKnowledgeSession) workingMemory).fireAllRules(); When it was working, I included a retract in my rule and flushed all the facts from the memory and since then it is not working.

Add a fact User with field group, set appropriately, and extend the conditions of your rules as required. I don't think that using agenda groups would be a good approach. -W On 21/08/2012, Rana <ven12344(a)yahoo.com&gt; wrote:

*DISCLAIMER: PLEASE NOTICE THAT THIS IS NOT RECOMMENDED, AND IN ANY CASE SHOULD BE DONE WITH ***EXTREME*** CARE.* This said, you need to create a KnowledgeBase passing a RuleBaseConfiguration. Take a look at RuleBaseConfiguration.getComponentFactory(), which returns a ReteooComponentFactory. This class controls the sub-factories used to build parts of the RETE network. In particular, you will need to hack the NodeFactory (guess what it does :)) So, in reverse order: - Create a KnowledgeBase using a custom configuration /KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase( rbc );/ - When you create the configuration, do not use the interface, but the actual implementation /RuleBaseConfiguration rbc = (RuleBaseConfiguration) KnowledgeBaseFactory.newKnowledgeBaseConfiguration();/ - Set a custom NodeFactory in the configuration /rbc.getComponentFactory().setNodeFactoryProvider( myNodeFactory );/ - The nodefactory should extend the appropriate methods and returned customized nodes. For example, to hack the alpha nodes: /org.drools.reteoo.builder.NodeFactory myNodeFactory = new DefaultNodeFactory() { public AlphaNode buildAlphaNode(int id, AlphaNodeFieldConstraint constraint, ObjectSource objectSource, BuildContext context) { return new MyAlphaNode( /* args from super constructor here */ ); } };/ - Your custom nodes should add the desired behaviour. For example, the custom AlphaNode could override the "assertObject" method ( see : https://github.com/droolsjbpm/drools/blob/master/drools-core/src/main/jav... ) / ... if ( isAllowed(...) ) { ... } else { // not present in the original // here, a particular object failed to satisfy a given constraint } / -- View this message in context: http://drools.46999.n3.nabble.com/modify-and-update-is-not-working-in-the...
