title: How to populate Jasper report For a list of objects where each object has a list of objects inside?
body: <p>Object is like this</p>
  
  <pre><code>class jobVO{ 
      ...
      List&lt;taskVO&gt; tasks;
      ...
  }
  class TaskVO{
      String name;
      ...
  }  
  </code></pre>
  
  <p>I need to pass List to a jrxml and print.</p>
  
  <p>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.</p>
