JasperPrint retrieved slowly

2004-05-17 20:22

I used ireport to generate xml and jasper files for my reports. I want to link those reports with my program, so I tried to retrieve JasperPrint using datasource which contains more than 30000 records. Getting the datasource took ard 3 seconds but getting the JasperPrint took more than a min.

 

JasperPrint jasperprint=null;

JRResultSetDataSource ds = getDataSource();

jasperPrint = JasperManager.fillReport(filename, null, ds);

JRViewer jrv = new JRViewer(jasperPrint);

 

It took a long time before i can view the report. How can i speed up the process?

Thanks!
