parameters and subreports

[emi]

hello I have simple master report with subreports. How can I put the parameters into subreports ?

When I put this in main report everything is ok, but in subreports it's value null

 

Map<String, Object> params = new Hashtable<String, Object>();

 

JasperReport jasperReport = JasperCompileManager.compileReport( classLoader.getResource( mainReport.getFile() ).getFile() );

 

for ( Report report : mainReport.getSubReports() ) {

JasperReport reportCompiled = JasperCompileManager.compileReport( classLoader.getResource( report.getFile() ).getFile() );

params.put( report.getName(), reportCompiled );

 

if ( report.hasSubreports() ) {

 

for ( Report subReport : report.getSubReports() ) {

 

JasperReport subReportCompiled = JasperCompileManager

.compileReport( classLoader.getResource( subReport.getFile() ).getFile() );

params.put( subReport.getName(), subReportCompiled );

params.put( "text", new String( text ) );

 

}

}

}

return JasperFillManager.fillReport( jasperReport, params ,new JREmptyDataSource() ); [file name=declaration_mainData.jrxml size=28976]http://www.jasperforge.org/components/com_joomlaboard/uploaded/files/declaration_mainData.jrxml[/file]

Im a newbie but maybe didnt reference the parameter of the subreport in the main jrxml file?

 

<parameter name="ProductsSubreport" class="net.sf.jasperreports.engine.JasperReport">

</parameter>

 

 

btw, im curious. where did you get function hasSubreports()? Thats nifty, simple xml parsing or part of API i didnt see in javadoc?
