How Fill a SubDataset with JRDataSource

[NeO_GeO]

Hi all,

Everyone knows the way to populate a report in java enviroment by implementing the class JRDataSource:

 

JasperFillManager.fillReport(JasperReport jReport,JRDataSource dataSource,HashMap lParameters)

 

but how to populate a SubDataset with a name inside the report  with an implementation of JRDataSource ?

 

I have not found a documention or an example about this.

 

Hoping for an example of java code 

in the meantime I thank you.

You can create a JRDataSource parameter in the master and use its value as subdataset data source:

<parameter name="SubDataSource" class="net.sf.jasperreports.engine.JRDataSource"/>...<datasetRun subDataset="..">  <dataSourceExpression>$P{SubDataSource}</dataSourceExpression></datasetRun>

//in your Java codelParameters.put("SubDataSource", mySubDataSource);

HTH,

Lucian

Or you can use better $P{REPORT_DATA_SOURCE} with fillReport method
