如何在Jasper报告中显示ArrayList的值

Question

I am using jasper report 5. I am able to print simple variable values, but i am not getting how to print values of ArrayList variable.

I have included

<field name="billNo" class="java.lang.Long"/>
    <field name="paymentType" class="java.lang.String"/>
    <field name="subTotal" class="java.lang.Float"/>
    <field name="vat" class="java.lang.Float"/>
    <field name="total" class="java.lang.Float"/>

I am printing above fields like

 <textField>
        <reportElement x="276" y="70" width="180" height="15"/>
    <textElement/>
        <textFieldExpression><![CDATA[$F{total}]]></textFieldExpression>
    </textField>

same for others.That is working fine.

Now I have an ArrayList customerList . which have fields customerName , address etc.

I want to show these values using jasper report how to do this.

Answer 1

Create another subreport for Customer List like :

<subreport>
<reportElement x="0" y="0" width="0" height="0"></reportElement>
<subreportParameter name="SUBREPORT_DIR"><subreportParameterExpression><![CDATA[$P{SUBREPORT_DIR}]]></subreportParameterExpression>
</subreportParameter>
<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{customerList})]]></dataSourceExpression>
<subreportExpression><![CDATA[$P{SUBREPORT_DIR} + "CustomerList.jasper"]]></subreportExpression>
</subreport>

In the new sub report

<textField>
        <reportElement x="276" y="70" width="180" height="15"/>
    <textElement/>
        <textFieldExpression><![CDATA[$F{customerName}]]></textFieldExpression>
    </textField>
