在hibernate中找不到组件类
每当我尝试将ireport与netbeans中的hibernate连接时，就会出现错误“component class not found:Sustainability.ProductionSavingId”。当我运行该程序时，它不会显示任何错误，但当我尝试使用hibernate将ireport连接到数据库时，它会抛出错误。我已经添加了所需的类路径和jar文件在hibernate中找不到组件类,hibernate,netbeans,jasper-reports,ireport,Hibernate,Netbeans,Jasper Reports,Ireport,每当我尝试将ireport与netbeans中的hibernate连接时，就会出现错误“component class not found:Sustainability.ProductionSavingId”。当我运行该程序时，它不会显示任何错误，但当我尝试使用hibernate将ireport连接到数据库时，它会抛出错误。我已经添加了所需的类路径和jar文件 <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-
