Title Body

Background: I'm working on an application that transforms an input object into one of two output objects based upon a set of drools rules. The output object is not known until runtime and it is created in the first rule to execute. Here is the rule that creates the output object and an example transformation rule: rule "Initialization" dialect "java" salience 1000 no-loop true when t : Trade() then if(t.getTran().getInsType().equalsIgnoreCase("EEO") || t.getTran().getInsType().equalsIgnoreCase("EEF")) { insert(new Option()); } else { insert(new Swap()); } end rule "Example Rule" dialect "java" when t : Trade() opt : Option() then opt.setCounterpartyName(t.getTran().getCParty()); end Here is the code that is calling the rules: private void test(){ for(File xmlFile : getXmlFilesFromDirectory(XML_DIRECTORY)) { Trade trade = (Trade)unmarshall(xmlFile, Trade.class); KnowledgeBase kbase = readKnowledgeBase(); StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession(); KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newConsoleLogger(ksession); List<Command> commands = new ArrayList<Command>(); commands.add(CommandFactory.newInsert(trade, "trade")); commands.add(CommandFactory.newFireAllRules()); ExecutionResults results = ksession.execute(CommandFactory.newBatchExecution(commands)); logger.close(); } } private static KnowledgeBase readKnowledgeBase() throws Exception { KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(ResourceFactory.newClassPathResource("security-transformation.drl"), ResourceType.DRL); KnowledgeBuilderErrors errors = kbuilder.getErrors(); i
