How to populate Jasper report For a list of objects where each object has a list of objects inside?

Question

Object is like this

class jobVO{ 
    ...
    List<taskVO> tasks;
    ...
}
class TaskVO{
    String name;
    ...
}

I need to pass List to a jrxml and print.

I tried with subreports. but there I couldn't find a way to pass the params. Also tried with collection datasource also. There the problem I found was need to mention the factory method. My requirement is to create this report dynamically.
