Question

I want to call JasperFillManager.fillReport(filePath+”.jasper”, param, con); where param is supposed to accept type Map. is there any solution

Answer 1

Simply use the constructor taking another map as an argument:

Map<String, Object> map2 = new HashMap<String, Object>(map);

See this example:

import java.util.HashMap;
import java.util.Map;

public class Test5 {

    public static void main(String[] args) {
        HashMap<String, Integer> map = new HashMap<String, Integer>();
        map.put("1", 1);
        Map<String, Object> map2 = new HashMap<String, Object>(map);
        // etc...
    }
}
