当我在iReport 5.1.0中预览时，JasperReports的报告执行得很好。它包含一个饼图，当我需要从jsp文件运行它时出现问题。
错误消息是：
java.lang.NoClassDefFoundError: Could not initialize class net.sf.jasperreports.charts.type.PlotOrientationEnum
我的环境是：WIN 7-JDK7-NetBean 8。
二手图书馆：
烧烤1.5-beta1.jar
commons-beanutils-1.8.2.jar
commons-collections-3.2.1.jar
commons-digester-2.1.jar
commons-javaflow-20060411.jar

jasperreports-fonts-5.0.4.jar
jcommon-1.0.15.jar
