Hi.Â

Â

Yes, this is possible. One solution might be to pass your Connection object to the report parameters map.Â

Â

//code snipÂ

HashMap map = new HashMap();Â

Connection myConnection = getConnection();Â

map.put("myConn", myConnection);Â

Â

JasperFillManager.fillReport(report, map, new JRBeanArrayDataSource(MyFactory.getBeanArray()));Â

Â

In the subreport elements, you are now able to get the Connection object with <dataSourceExpression><![CDATA[((HashMap)$P{REPORT_PARAMETERS_MAP}).get("myConn")]]></dataSourceExpression>Â
