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 where Something has a property of type List
• If it is one for the whole report, pass it as a parameter (params above).
