How to pass ArrayList to JasperReports?

Question

I\'m new to JasperReports. I want to pass ArrayList to subreport of subreport.

I have master report which contains one subreport1 and this

Answer 1

It's done by passing a collection data-source: new BeanCollectionDataSource(yourArrayList);

And then to obtain the JasperPrint object:

JasperPrint jasperPrint = 
      JasperFillManager.fillReport(jasperReport, params, dataSource);

To pass to a subreport, you have two options:

• If it is a subreport-per-row, simply have the array as a property of the bean. I.e. List<Something> where Something has a property of type List<AnotherThing>
• If it is one for the whole report, pass it as a parameter (params above).

Answer 2

Step:1 define a field like
field name="listCusipData" and class="java.util.ArrayList"

Step:2 use this expression inside your sub report dataSourceExpression
new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{listCusipData},false)

Answer 3

You can do it using lists and/or subreports, datasources and JRBeanCollectionDatasource.

Check this example:

It's in Spanish, but by your name I guess you will be able to read it ;)

For non Spanish speakers you still can use it as at the end of the tutorial you can find the XML with the jrxml templates.
