Jasper report iterate over array list [duplicate]

Question

how can I create report that will iterate over arraylist in detail section that is passed as parameter in Jasper report?

Is that even possible? I searched and I found soloution that you have to add ArrayList as datasource. How do I do that?

Answer 1

You can create an SubReport an pass the ArrayList as DataSourceExpression:

        <subreport>
            ...
            <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($P{arrayList})]]></dataSourceExpression>
            <subreportExpression><![CDATA["subreport.jasper"]]></subreportExpression>
        </subreport>
