还有那种如com.opensymphony.xwork2.ModelDriven形式的包在哪里啊？我找遍了struts整个包都没有找着！！

    }



    public void validate() {

        if (model.getClientName() == null || model.getClientName().length() ==0) {

            addFieldError("clientName", "The client name is empty");

        }

    }



    public void setId(String id) {

        if (id != null) {

            this.model = ordersService.get(id);

        }

        this.id = id;

    }
