I received this error while generating a report. Does anyone know how to fix this?

JasperReports v. 2.0.1

CentOS release 5.3 (Final)

This may help, it was located a few lines about the error message:

 INFO [uPC:http-8080-3] xml.XmlBeanDefinitionReader.[uPC:] Nov/08 13:21:53 - Loading XML bean definitions from URL [jar:file:/.../WEB-INF/lib/jasperreports-fonts-3.6.2.jar!/net/sf/jasperreports/fonts/fonts.xml]

My bad, should be JasperReports 3.7.4
