Please help me to figure the issue. I clicked on Dataset and Query dialog icon and entered class name in javabean as com.pojos.jasper.ReportDataExport. I can see my method getFrameElement() getting populated. I cliked ADD SELECTED FIELDS and clicked OK. Then I pulled the field $F{frameElement} into the report. But it gives NULL instead returning datalist . Expected output is the list of data in datalist. public List<String> getframeElement() { List<String> datalist = new ArrayList<>(); final int size1 = Export.getdetails().getdata().getdata().size(); for (int i = 0; i <= size1; i++) { final String data = Export.getdetails().getdata().getdata().get(i).getLongName(); datalist.add(data); } return datalist; }[/code]find the image of jasperreport.

I droped a table icon inside report and 1. Create new datasource with name Dataset1. Next it showed empty dataset without any field. Don’t know how to proceed with. Please help me out.
