BPM でユーザーの休暇ルールを作成しようとして、メソッドを作成しました (スニッパーは下に表示されます) が、jaxb オブジェクト インスタンスの作成時に例外が発生しました。 

ruleInfoType.setCreatedDate(DateUtility.getCalendarInTimeZone(DateUtility.TIMEZONE_TR));

インスタンスを作成する正しい方法について誰かが考えていますか?

BPM API オブジェクトの設定中に発生した問題は、objectFactory を使用していないことに関するものでした。私は oracle.bpel.services.workflow.user.model.ObjectFactory を使用しましたが、うまくいきました。

    public static void createVacationRule(String userNameOfRuleOwner, String targetUserName, Date beginDate, Date endDate) throws WorkflowException
    {
        IUserMetadataService iUserMetadataService = serviceClientFactory.getWorkflowServiceClient().getUserMetadataService();
        oracle.bpel.services.workflow.user.model.ObjectFactory userObjectFactory = new oracle.bpel.services.workflow.user.model.ObjectFactory();
        RuleInfoType ruleInfoType = userObjectFactory.createRuleInfoType();
        //RuleDetailType ruleDetailType = objectFactory.createRuleDetailType();
        RuleDetail ruleDetail = userObjectFactory.createRuleDetail();
        RuleActionType ruleActionType = userObjectFactory.createRuleActionType();
        RuleAssignmentType ruleAssignment = userObjectFactory.createRuleAssignmentType();

        StringBuilder ruleName = new StringBuilder("VekaletApp_");
        StringBuilder ruleDesc = new StringBuilder(userNameOfRuleOwner);

        //prepere ruleName Str
        ruleName.append(userNameOfRuleOwner);
        ruleName.append("_");
        ruleName.append(targetUserName);
        ruleName.append("_");
        ruleName.append(DateUtility.convertDateToString(beginDate, "dd.MM.yyyy"));
        ruleName.append("_");
        ruleName.append(DateUtility.convertDateToString(endDate, "dd.MM.yyyy"));

        //prepere ruleDesc Str
        ruleDesc.append("'s reassignment rule between ");
        ruleDesc.append(DateUtility.convertDateToString(beginDate, "dd.MM.yyyy HH:mm"));
        ruleDesc.append(" and ");
        ruleDesc.append(DateUtility.convertDateToString(endDate, "dd.MM.yyyy HH:mm"));

        //prepare ruleinfotype instance
        ruleInfoType.setRuleName(ruleName.toString());
        ruleInfoType.setDescription(ruleDesc.toString());
        ruleInfoType.setCreatedDate(DateUtility.getCalendarInTimeZone(DateUtility.TIMEZONE_TR));
        ruleInfoType.setStartDate(DateUtility.getCalendarOfDate(beginDate));
        ruleInfoType.setEndDate(DateUtility.getCalendarOfDate(endDate));

        //prepare owneruser principalref
        oracle.bpel.services.workflow.common.model.PrincipleRefType userOfRuleOwner = userObjectFactory.createViewGranteeType();
        userOfRuleOwner.setRealm("jazn.com");
        userOfRuleOwner.setType("USER");
        userOfRuleOwner.setName(userNameOfRuleOwner);

        //set owner user to ruleInfoType
        ruleInfoType.setOwner(userOfRuleOwner);

        //prepare targetuser principalref
        oracle.bpel.services.workflow.common.model.PrincipleRefType targetUser = userObjectFactory.createViewGranteeType();
        targetUser.setRealm("jazn.com");
        targetUser.setType("USER");
        targetUser.setName(targetUserName);

        //set target user to reassigne user
        ruleAssignment.setAssignee(targetUser);
}

    ruleActionType.setReassign(ruleAssignment);
    ruleActionType.setActionType(IUserMetadataService.RULE_ACTION_REASSIGN);

    ruleDetail.setAction(ruleActionType);
    ruleDetail.setGeneralInfo(ruleInfoType);

    iUserMetadataService.createRule(iWorkFlowContext, ruleDetail);
