Hi, PFA the model jar and decision table that I have created . myTest.jar contains my model class 'AmountPojo' and currently I have written only one PF rule using this 'AmountPojo' class I have done following things successfully on guvnor GUI : - uploading of model jar in a package(named Test) - uploading decision table xls in same package - 'save and validate configuration' and 'building package'after above steps - Creating test scenario for testing that my rule is working fine Now, I wish to utilize this package in my application through changeset.xml. For this, I wrote something like : <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation=' http://drools.org/drools-5.0/change-set drools-change-set-5.0.xsd' > <add> <resource source=' https://ofbiz.apache.org:8443/drools-guvnor/org.drools.guvnor.Guvnor/pack... type='DRL' /> </add> </change-set> Also, in my code I have created knowledge agent like dis : kagent = KnowledgeAgentFactory.newKnowledgeAgent( "MyRuleAgent" ); String changesetUrl = "file:"+currentWorkingDirectory+"/framework/drools/config/changeset.xml"; kagent.applyChangeSet( ResourceFactory.newUrlResource( changesetUrl ) ); Using this 'kagent' I have created knowledge base like dis : if(kbase==null){ kbase = kagent.getKnowledgeBase(); } When kagent.applychaneset line executes, it throws following error : [Error: Failed to compile: 4 compilation error(s): - (1,9) unqualified type in strict mode for: amtEntity - (1,9) unqualified type in strict mode for: amtEntity - (1,15) unqualified type in strict mode for: basic - (1,40) unable to resolve method using strict-mode: java.lang.Object.setHra(java.lang.Object)] [Near : {...

Any idea why this is occuring ? How to communicate about 'AmountPojo' Type in code ? Also, After this, I wanted to know the steps for 'inserting fact type object for AmountPojo' in the session created. For this I read in docs that use following lines of code : // Retrieve the generated fact type FactType cheeseFact = ruleBase.getFactType( "org.drools.generatedbeans.Cheese" ); // Create a new Fact instance Object cheese = cheeseFact.newInstance(); cheeseFact.set( cheese, "type", "stilton" ); But, I didnt find any method like KnowledgeBase.getFactType(String fullyQualifiedfactTypePath) . There is only one KnowledgeBase.getFactType(String pckname,String factTypeName) method in it Please let me the know the right way of achieving this .
