I found a solution, create subreport with xml data source in masterSubreport, use connectionType "Use a data source Expression" and apply data source expression like this: new net.sf.jasperreports.engine.data.JRXmlDataSource("/path_to_xml_file/file.xml").dataSource("/root/field[@id="+$F{FIELD}+"]")[/code]

What did you mean match main and sub dataset in the subreport, can you describe please? I rephrase the question I'm need, that if subreports dont return data, a main report should not print blank page... As I understood the decision at the report level does not exist, and I m need to use subreport query in main query?

I have report with main report query that return one row always select to_date($P{param0},'yyyy-mm-dd HH24:MI:SS') as dtstart,to_date($P{param1},'yyyy-mm-dd HH24:MI:SS') as dtendfrom dual[/code]In detail bands I have crosstab reports, that have own datasets, when crosstab dataset dont return data, iReport print blank page but in report property "When no data"="NoPages", how to avoid it and dont print blank page. I know one method for this use crosstabs query in main query how in this example: select to_date($P{param0},'yyyy-mm-dd HH24:MI:SS') as dtstart,to_date($P{param1},'yyyy-mm-dd HH24:MI:SS') as dtendfrom dualwhere exists (select * from crosstabdataset)[/code]but whether there are other ways?
