我是素颜的新手。请在下面查看我的代码。

测试.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>

        //getter and setter methods
    }

















}

我需要从 testbean.java 获取数据。但我无法在数据表中显示我的数据。这是我得到的错误

    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
phaseId=RENDER_RESPONSE(6)

Caused by:
javax.el.PropertyNotFoundException - Property 'orderNo' not found on type my.com.mesiniaga.sphere.web.GeneralServiceBean$Order
at javax.el.BeanELResolver$BeanProperties.get(BeanELResolver.java:237)

有人有解决办法吗？
