java - データテーブルは項目 JSF を取得できません

Question

プライムフェイス初心者です。以下の私のコードを見てください。

Test.xhtml

<h:dataTable  var="test" value="#{generalServiceBean.orderList}" >

             <h:column>

                <f:facet name="header">Order No</f:facet>


             </h:column>


            <h:column>

                <f:facet name="header">Order No</f:facet>

            <h:outputText value="#{test.orderNo}" />


             </h:column>




          </h:dataTable>

Testbean.java

    private static final long serialVersionUID = 1L;



    private String title ="General Eligibility ";



    private static final ArrayList<Order> orderList = 
            new ArrayList<Order>(Arrays.asList(

            new Order("A0001", "Intel CPU", 
                    new BigDecimal("700.00"), 1),

            new Order("A0003", "Dell Laptop", 
                    new BigDecimal("11600.00"), 8),
            new Order("A0004", "Samsung LCD", 
                    new BigDecimal("5200.00"), 3),
            new Order("A0005", "A4Tech Mouse", 
                    new BigDecimal("100.00"), 10)
        ));


    public ArrayList<Order> getOrderList() {
        return orderList;
    }




    public String getTitle() {
        return title;
    }






    public void setTitle(String title) {
        this.title = title;
    }




    public static class Order{

        String orderNo;
        String productName;
        BigDecimal price;
        int qty;
        boolean editable;

        public Order(String orderNo, String productName, BigDecimal price, int qty) {
            this.orderNo = orderNo;
            this.productName = productName;
            this.price = price;
            this.qty = qty;
        }

        //getter and setter methods
    }

















}

testbean.java からデータを取得する必要があります。しかし、データをデータテーブルに表示できません。ここに私が得るエラーがあります

    javax.el.PropertyNotFoundException: Property 'Order' not found on type my.com.mesiniaga.sphere.web.GeneralServiceBean$Order

viewId=/pages/generalEc.xhtml
location=D:\springsource\vfabric-tc-server-developer-2.8.2.RELEASE\base-instance\wtpwebapps\CGC_Dev\pages\generalEc.xhtml

誰でも解決策を得ましたか？
