问题：

为什么JasperReports服务器显示空报表？

我在Jaspersoft Studio中创建了一个示例报告

并将创建的报表发布到服务器连接。但当我打开服务器并检查发布的同一项时，它显示为空报表。为什么会这样？

JasperReports服务器上的报表为空，因为发布数据源时很可能没有选择数据源。

您已经使用Jaspersoft Studio附带的示例DB创建并测试了报告。服务器也必须可以访问相同的数据，或者在本例中是具有相同结构的相同数据库表。在发布报表时指定。

幸运的是，服务器上有一个数据源的表结构与Studio中的表结构相似。您需要做的是在同一位置和报表发布向导中重新发布报表，以选择数据源from repository并输入以下路径：

注意：Studio中的服务器连接是使用jasperadmin用户完成的。
