我能够显示简单到jasper的报告，但无法显示arrayList值。 我有一个arrayList变量customerList。其中只包含一个客户详细信息，我想在jasper报告中显示其名称和地址。
如何做到这一点。 我的代码如下：
我正在采取行动类
public class SubmitBillAction extends ActionSupport {
private float subTotal;
private float vat;
private float total;
private ArrayList<SubmitBillAction> list;
private ArrayList<CustomerAction> customerList;
//getter and setter
}
在struts.xml中
<action name="myJasperTest" class="iland.bill.SubmitBillAction" method="fetch">
<result name="success" type="jasper">
<param name="location">/pages/billing/billReport.jasper</param>
<param name="dataSource">list</param>
<param name="format">PDF</param>
</result>
</action>
在碧玉报告中
