1. 设计器下预览是否正常
2. 设计器左侧控制台或者服务器后台有详细报错，吧详细的完整错误信息贴一下吧

数据集类型是常规 sql 类型还是自定义数据集类型？
能否吧这个报表打成压缩包发上来看一下？
xiaohuihui • 6 年前

展现报表用 showReport.jsp，rpx 报表文件放到 reportFiles 目录下，URL 直接拼 showReport.jsp?rpx=xxx.rpx 即可

这个问题怎么解决的啊？

上面报错是数据集计算有问题，检查下数据集相关配置，比如数据集本身的语法，参数配置这些
如果参数是必须传值才能正常正常计算数据集，那么在报表–参数–值表达式那配置下默认值
