swing - Java JScrollPane- Multiple components -

i'm trying add 2 images inside jscrollpane. first image background , second 1 overlap first one. problem shows second image when run program!

please help

imageicon ii = new imageicon("mini_map.png"); jlabel label1=new jlabel(ii);  icon icon = new imageicon("mg.gif"); jlabel label2 = new jlabel(icon);  jscrollpane jsp=new jscrollpane();  jsp.getviewport().add(label1); jsp.getviewport().add(label2 ); 

jviewport single-child container, can't add 2 components.

to achieve overlap (that stack components in z-direction) in any container, you'r on own, built-in support poor. either have manage them in layeredpane (as mentioned already) or try overlaplayout
