Using map for jasper reports datasource

i used this for map-based datsource in jasper reports.


def action()
{
HashMap[] reportRows = new HashMap[2];

        HashMap row1Map = new HashMap();
        HashMap row2Map = new HashMap();


        row1Map.put("name", "aaditya");
        row1Map.put("lastname", "bhatta");
        row1Map.put("phone", "9848782444");
        row1Map.put("gender", "male");

        row2Map.put("name", "aaditya");
        row2Map.put("lastname", "bhatta");
        row2Map.put("phone", "9848782444");
        row2Map.put("gender", "male");

        reportRows[0] = row1Map;
        reportRows[1] = row2Map;

}

now you can use map reportRows for the datasouce in you jasper reports .
as ::

        chain(controller:'jasper', action:'index', model:[data:reportRows],params:params)
