Closing an open task programatically

Question

HI,
I have created a custom component in order to establish connection to BPM .
The flow is such that , the connection gets established and i need to fetch the tasks based on the workflowInstance and user ID specified.
I am able to fetch the tasks from which i extract the task state.
Need to close the state of an open task i.e need to update the state of the task to close. Not able to do it.
How do i achieve this?
This is the piece of code that is supposed to perform the functionality.
Please have a look and provide your inputs in order to achieve the needed.
Function Call:
this.updateTaskOutCome(task1, "CLOSE");
Function Defnition:
public int updateTaskOutCome(final task,
                                 final String outcome) {
        // variable to show success or failure
        int success = 0;
        // creating reference for TaskQueryService
        TaskQueryService taskQueryService = null;
        // creating reference for WorkflowContextType for admin context
        WorkflowContextType adminContext = null;
        // creating reference for WorkflowContextType for user context
        WorkflowContextType userContext = null;
        TaskService taskService = null;
        oracle.bpel.services.workflow.task.model.Task outcomeUpdatedTask =
            null;
        CredentialType adminCredentialtype = this.createAdminCredentialType();
        CredentialOnBehalfOfRequestType onBehalfRequestType =
            queryFactory.createCredentialOnBehalfOfRequestType();
        // calling getService method og BPMConnection
        //get taskQueryService Object from BPMConnection
        //taskService = getService("taskAction");
        //creating WorkflowContext for admin
        //setting admin context to onBehalfRequestType
        try {
            taskQueryService = (TaskQueryService)getService("taskQuery");
            adminContext = taskQueryService.authenticate(adminCredentialtype);
            onBehalfRequestType.setOnBehalfOfUser("username");// admin username given
            onBehalfRequestType.setWorkflowContext(adminContext);
            //creating WorkflowContext for user
           userContext= taskQueryService.authenticateOnBehalfOf(onBehalfRequestType);
            // getting BPM Client for performing user actions
            taskService = (TaskService)getService("taskAction");
            // creating UpdateTaskOutcomeType object and setting its property
            UpdateTaskOutcomeType updateTaskOutcomeType =
                taskActionFactory.createUpdateTaskOutcomeType();
//            //setting outcome
            updateTaskOutcomeType.setOutcome(outcome);
            //setting task
            updateTaskOutcomeType.setTask(task);
            // setting userContext
           updateTaskOutcomeType.setWorkflowContext(userContext);
            // calling webservice operation for performing user action
            //setting success variable
            outcomeUpdatedTask =
                    taskService.updateTaskOutcome(updateTaskOutcomeType);
        } catch (StaleObjectFaultMessage e) {
            Report.trace("mysectionstring",
                         "inside staleobject fault message catch block", null);
//        } catch (WorkflowErrorMessage e) {
//            TaskQueryServiceFaultType faultInfo = e.getFaultInfo();
        } catch (Exception e) {
            e.printStackTrace();
        if (outcomeUpdatedTask != null) {
            success = 1;
        return success;
Thanks in advance,
