I having this problem when I try to use the runReportToPdf method....

 

Error at Generate: java.lang.ClassCastException: dori.jasper.engine.JasperPrint

java.lang.ClassCastException: dori.jasper.engine.JasperPrint

at dori.jasper.engine.JasperFillManager.fillReport(JasperFillManager.jav

a:286)

at dori.jasper.engine.JasperRunManager.runReportToPdf(JasperRunManager.j

ava:280)

at REPORT.Report.generateBrowser(Report.java:84)

 

my code are something like this:

byte[] bytes = null;

mainFile = dir + "abc.jrprint";

bytes = JasperRunManager.runReportToPdf(mainFile, para,new JREmptyDataSource());

......

 

Any one have any ideas what went wrong?
