jasperreport生成报表问题

求高手解惑，我用jasperreport生成了报表后，每次运行，控制台都打印出
- Loading XML bean definitions from URL [jar:file:/D:/WisdomCRM_IPCC/WebContent/WEB-INF/lib/jasperreports-fonts-3.7.1.jar!/net/sf/jasperreports/fonts/fonts.xml]
- Found two components for namespace http://jasperreports.sourceforge.net/jasperreports/components
请问这是怎么了了？
