copy your subreport jasper file from ireport folder and place it in the directory of your master report

I've found that on reports (especially on sub-master reports) that every report the system must be attached to some data source. Since I'm going after data in a SQL Server database on all my subreports, I just do a SELECT 1 as temp as the data source for the report 'with no data'. Hope that helps. Don't know why I have to do it, but that's the way I found to work around it.

In your main report you can make the subreport have a datasource expression and then make the expression itself this:

 

Code:

new JREmptyDataSource(1)
