nested grouping

2003-08-28 14:40

I am wondering if Jasper is capable of producing reports with nested grouping, basically, I want to loop through an array of enrollers, underneath each enroller, I want to loop through an array of locations; underneath each location, I want to loop through an array of employees enrolled, and under each employee, I want to loop through 0-many dependents, I want to get summary data for each grouping. If using nested subreports, how do I pass JRDataSource? Any sample is greatly appreciated.
