Question

在尝试在BPM上创建用户休假规则时，我编写了一个方法（可以在下面看到剪切器），但是当jaxb对象实例创建时发生了异常。

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

java.lang.NullPointerException

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

action.setReassign(ruleAssignment);

iUserMetadataService.createRule(ctx, (RuleDetail)ruleDetail);
}

有没有人知道创建实例的正确方法？

设置BPM API对象时出现的问题是不使用objectFactory。我使用了oracle.bpel.services.workflow.user.model.ObjectFactory并且它工作正常，希望下面的代码片段有帮助。

    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);

如何使用adf平台在Oracle BPM上创建bpm休假规则？
