Hibernate with subReport

2005-05-11 09:38



I retrieved list of hibernate objects contains subsets of another hibernates. Using this list of top object, I'd like to create muti-layered reports like main report, sub1 report, and sub2 report.


Can anyone share how to do that?

I ll give you an example:

You have an object Student that have some fields



Set notes = new HashSet()


your main report have a JRBeanCollectionDataSource based on the set of Students.

Then in your main report you will have three fieds





in your main report now ,your subReport is declared like this

<subreport isUsingCache="true">




<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource((java.util.Collection)($F{notes}))]]></dataSourceExpression>




hope it helps
