Is specifying DataSource mandatory?

[apx1sharma]

 I was writing a simple program for creating a basic Jasper report.

My reports were blank. After doing some googling, I realised below statement was wrong:

JasperFillManager.fillReportToFile("HelloJasper.jasper",jasperParameter);

I added a DataSource in above line and things started working.

JasperFillManager.fillReportToFile("HelloJasper.jasper",jasperParameter, new JREmptyDataSource());

 

My question is: Is this mandatory to provide a Datasource for creating Report? I mean, can't my program create Reports without a DataSource()?

There is overriden version of fillReport()  in JasperFillManager.class that does not accept DataSource. What is that for?
