Jasper report iterates over array list

Question

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

Is it possible? I searched and I found a solution that you should add an ArrayList as a data source. How to do it?

Hi

Answer 1

You can create a SubReport to pass an ArrayList as an expression of a DataSourceExpression:

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