I did not understand the relationship between objects.
Can you explain how relate objects of master report and subreport?

See example of using subreport. May be this helps http://community.jaspersoft.com/questions/543298/creating-table-structure-assorted-java-bean-structure-one-field-and-list-datasource

for both main and subreport i am passing the parameters through main report.

for Subreport i have created mapping for the individual parameter.

and instead of conection i have passed JrBeanCollectionDatasourse in fillManager() method...

I hope this information may answer your question. If you  are still unclear with the information, you can ask again.. please refer the code i have  attached and the two reports master(report2) and subreport(report3) .. waiting for the help..

thanks in advance..

Usual in master-detail report we have one master object (displayed in master report) and some childs of master object (displayed in subreport).

 

It is clearly seen in the discussion threads on the link in my previous answer.

Are you seen this?

 

In your case subreport displayed only after all records of main report.

This is what you wanted? Then pass Collection as parameter into main report and define DataSource expression for subreport, using this collection as parameter for method (for example createMyDataSource($P{mainReportParam}) ) which implements JRDataSource interface

Hey.,, Finally I have done it..

Actually  datasourse was not going in subreport.. so i have changed the property of when no data to all sections,no data...

then i have passed the collection variable where i have fetched the subreport records..

by using   parameters.put("shape_data_all",allShape_Caliberation);

then i have created a parameter in main report.. and changed its class to java.Util.Collection..

then in subreport property, connection type=   Use a datasource expression

Data Source Expression    new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($P{shape_data_all})

Then added the fields in the subreport same as i am having the bean properties..

Thank you..
