【问题描述】：
我是 JasperReports 的新手。我做了一些简单的报告，但没有这么复杂。我在论坛上搜索了一天以上，但我无法让它工作。
我得到的错误：
从 bean 检索字段值时出错：eventPlanTimeSlotBeanDataSet
如果有人能帮我把它变成摇滚，我将非常感激。
提前致谢， 汤姆
我的豆子：
public class EventPlanTimeSlotBean {
private String timeSlot;
private List<OrganizerResultReportBean> orgResultBeans = new ArrayList<OrganizerResultReportBean>();
public EventPlanTimeSlotBean(String timeSlot, List<OrganizerResultReportBean> orgResultBeans) {
this.timeSlot = timeSlot;
this.orgResultBeans = orgResultBeans;
}
public String getTimeSlot() {
return timeSlot;
}
public void setTimeSlot(String timeSlot) {
this.timeSlot = timeSlot;
}
public List<OrganizerResultReportBean> getOrgResultBeans() {
return orgResultBeans;
}
public void setOrgResultBeans(List<OrganizerResultReportBean> orgResultBeans) {
this.orgResultBeans = orgResultBeans;
}

填写报告：
try {
jasperPrint = JasperFillManager.fillReport(jreport, meetingResultMap,
new JRBeanCollectionDataSource(getDataSource(session, searchTask, eventPlan)));
} catch (JRException e) {
throw new LocalizedException("meeting_report_pdf_could_not_be_created" + ": " + e.getMessage());
}
