ireport custom datasource

[sazoo25]

I have this program, which I will be using arraylist as the datasource. The problem is how do I access the arraylist in ireport?

 

here's part of the code:

 

ArrayList results = (ArrayList)session.getAttribute("pdf");

JasperPrint jasperPrint = JasperManager.fillReport(jasperReport,parameters,new JRBeanCollectionDataSource(results));

 

thanks

If arraylist is an array of properly formatted beans, then you just refer to each field in the bean as a field in the report.

i.e.

 

public class Test {

private String myTestString;

 

public void setMyTestString(String s) {myTestString = s;}

public String getMyTestString() {return myTestString;}

}

 

The field in this instance would be $F{myTestString}.

 

HTH,
