Hi Maciej:
            I  hava two face , one of face from java input ,anthor one in rules new insert ,both of them need to retuan in java code ;and i use kie-server java client like below code : i want  get the location object from "out" OutIdentifier but its return all object contains last session fact;
 so I need clear old fact from last session in work memory;
           about clear old fact from last session in work memory, I need to close  manually？ but i not find related API
               

 private static String url = "http://192.168.0.100:8080/kie-server/services/rest/server";


    private static String username = "kieserver";
    private static String password = "kieserver1!";
    private static String container = "mary";
    private static String kieSession = "kiesession";

    public static void main(String[] args) {
        Student student = new Student();
        student.setName("tom");
        KieServicesConfiguration config = KieServicesFactory.newRestConfiguration(url, username, password);
        config.setMarshallingFormat(MarshallingFormat.JSON);
        config.setTimeout(30000L);

        KieServicesClient client = KieServicesFactory.newKieServicesClient(config);
        RuleServicesClient rules = client.getServicesClient(RuleServicesClient.class);

//        boolean deployContainer = true;
//        KieContainerResourceList containers = client.listContainers().getResult();
//        // check if the container is not yet deployed, if not deploy it
//        if (containers != null) {
//            for (KieContainerResource kieContainerResource : containers.getContainers()) {
//                if (kieContainerResource.getContainerId().equals(container)) {
//                    System.out.println("\t######### Found container " + container + " skipping deployment...");
//                    deployContainer = false;
//                    break;
//                }
//            }
//        }
//
//
//        // deploy container if not there yet
//        if (deployContainer) {
//            System.out.println("\t######### Deploying container " + container);
//            KieContainerResource resource = new KieContainerResource(container,
//                    new ReleaseId("u51", "test", "0.0.1-SNAPSHOT"));
//            client.createContainer(container, resource);
//        }

        KieCommands cmdFactory = KieServices.Factory.get().getCommands();

        List<Command<?>> commands = new LinkedList<Command<?>>();
        GetObjectsCommand getObjectsCommand = new GetObjectsCommand();
        getObjectsCommand.setOutIdentifier("out");

        commands.add(cmdFactory.newInsert(student, "student"));
        commands.add(getObjectsCommand);

        commands.add(cmdFactory.newFireAllRules());

        ServiceResponse<org.kie.api.runtime.ExecutionResults> response = rules.executeCommandsWithResults(container,
                cmdFactory.newBatchExecution(commands, kieSession));
        System.out.println(response.getMsg());
        ExecutionResults result = response.getResult();
        System.out.println(result.getFactHandle("out"));
        Collection<String> identifiers = result.getIdentifiers();
        for (String string : identifiers) {
            //System.out.println(string);
        }
        List<Location> results = new ArrayList<Location>();

        ArrayList objects = (ArrayList) result.getValue("out");
        System.out.println(objects.size()); // its will get all object Contains the last sessions object ; 
        for (Object ob : objects) {
           // System.out.println(ob);
            // Location lo = (Location)ob;
            // System.out.println(lo.getName());
        }
        //System.out.println(objects);


        student = (Student) result.getValue("student"); // its get right
        System.out.println(student.getAge());
        System.out.println(student.getVersion());
    }

seems like you use stateful session while you should most likely use stateless. Make sure that ksession is stateless in kmodule.xml of your project then it will dispose ksession after request so all facts will be disposed as well.

Hi caicongyang,

You can consider using a query, which I wrote about in a response to the other thread.

Have you tried using the QueryService?

https://docs.jboss.org/jbpm/v6.4/userguide/ch05.html#d0e2576

Regards,

[caicongyang]

Hi  Ged:
           Is there no other better way? In addition to query
