Thanks, Problem solved I updated the mortgage example to use KnowledgeAgent & ChangeSet.xml (files included below) & everything works with 5.1 guvnor. Now if this Pom can only sort out the pom.xml for the fusion examples I'd be really happy as I could get back to evaluate fusion for use if a project. I'm fighting against a group that are pushing Progress's CEP but I'm having problems just getting the fusion example running. --------------- MortgageApplication.java ---------------------------- package com.notidiots; import org.drools.KnowledgeBase; import org.drools.agent.KnowledgeAgent; import org.drools.agent.KnowledgeAgentFactory; import org.drools.definition.type.FactType; import org.drools.io.ResourceFactory; import org.drools.runtime.StatelessKnowledgeSession; public class MortgageApplicationTest511 { /** * @param args * @throws IllegalAccessException * @throws InstantiationException */ public static void main(String[] args) throws InstantiationException, IllegalAccessException { KnowledgeAgent ka = KnowledgeAgentFactory.newKnowledgeAgent("MyAgent"); ka.applyChangeSet( ResourceFactory.newFileResource("bin/ChangeSet.xml") ); KnowledgeBase kb = ka.getKnowledgeBase(); FactType appType = kb.getFactType("mortgages", "LoanApplication"); FactType incomeType = kb.getFactType("mortgages", "IncomeSource"); Object application = appType.newInstance(); Object income = incomeType.newInstance(); appType.set(application, "amount", 25000); appType.set(application, "deposit", 1500); appType.set(application, "lengthYears", 20); incomeType.set(income, "type", "Job"); incomeType.set(income, "amount", 65000); StatelessKnowledgeSession ks = kb.newStatelessKnowledgeSession(); ks.execute( new Object[] {application, income} ); System.out.println(application); } } -------------------- ChangeSet.xml ---------------------------------------------- <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 http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... <add <resource source='http://localhost:8080/drools-5.1.1-guvnor/org.drools.guvnor.Guvnor/package/mortgages/TEST' type='PKG' basicAuthentication="enabled" username="admin" password="admin" / </add</change-set ---------------------------------------------------------------------------------- -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/How-to-modify-changes...
