您正在使用 XML 文件作为两个报告的数据源。要使子报表显示数据，您必须通过数据源表达式而不是连接表达式为其提供确切的数据源。子报告未在您的文件系统上找到 xml 文件。

转到子报表属性并清空“连接表达式”字段。然后用

((net.sf.jasperreports.engine.data.JRXmlDataSource) $P{REPORT_DATA_SOURCE}).dataSource("//")

您的 XML 文件似乎有一个空查询字符串，因此不需要 xpath 查询字符串。这个解决方案应该适用于Jasperstudio 6.x。

另一种解决方案可能是使用参数按钮将 $P{XML_DATA_DOCUMENT} 参数传递给上级报告。
