Hi,
I have to create a master/child report where the datasource is a JRDataSource.
How do I pass the "details" to the child report. How do I make use of the dataSourceExpression ?
For example, consider the following:
Cust=c1
Location=tempe
Cust=c2
Location=jersey
In the main report, I want to group by location and in the subreport show details of all orders where location=tempe.. Something like
Location
Tempe
OrderId=1, ProductId=2, Qty=3
OrderId=2, ProductId=2,Qty=3
Jersey
OrderId=3,ProductId=4,Qty=5
The datasource for the main report is a List of maps having name/value pairs. How do I invoke the subreport and pass data to the subreport where location=tempe in the first case
And location=jersey in the second, but without using sql in the subreport, only via JRDataSource.
Any help will be appreciated
Thank You
