Hi!

I'm deveoping on latest java jdk and Eclipse editor, I make reports by using iReport, but when I try to

use

JasperPrint jasperPrint = JasperFillManager.fillReport("myReport.jasper", parameters, getConnection());

throws a ClassNotFoundException when it tries to execute

JRLoader.loadObject(...); into fillReport.

I don't know hot to solve this problem

Thanks for your help
