Subreport within subreport

[johnbor]

Hi,

 I would like to use subreport inside another subreport. So the idea is that:

 Master report -> Subreport1 -> Subreport2.

  And i would like to see that in the end:

- PC Store1

--- Address: USA, Baltimore

--- Telephone number: xxxxx

--- Softvers: ( Subreport1 )

-----Description: Good stuff

-----Details: Very good stuff

-----Caution: Not very good stuff

-----Types: ( Subreport2 )

-------OS: Windows

-------Game: COD,WOW, etc.

- PC Store2

--- Address: ITA, Rome

--- Telephone number: xxxxxx

--- Softvers: ( Subreport1 )

-----Description: xxxx

-----Details:xxxx

-----Notion:xxxxx

-----Types: ( Subreport2 )

-------OS: Linux

The problem is that I don't find the appropriate data modell in Java. I tried to use the JRBeanCollectionDataSource way and the store and type data is ok, but i can't give the right data for subreport2.

Can anyone has experience in this area of Jasperreports ( 3.6.1 )??

There's nothing special about the second level of subreports.  So if you have a data model for the first subreport level, that's exactly what you need to have at the second level.

And what you need to have are list/collection fields at each leve, which you use as data source for the subreports by wrapping them in JRBeanCollectionDataSources.

Can this method that you suggested be applied if it dataSource is og type JRResultSetDataSource.

I tried passing JRResultSetDataSource as a parameter to subreports , but when I ran it says resultSet is closed.

Can you please help me on this .

Thanks,
