samifox (aka Shay Gaghe?) Please do not use this ID any more. It does not fit the at "JavaRanch Naming Policy" Two comments on your question. You have a DefaultListModel that you are adding to, but you never hook it up to your JList. You could try repainting.

Shay, You need to amend your code as follows: in ScrolledList make your JList like this JList list = new JList(dlm); (otherwise how does the JList know what to display) and in innerClass add your innerClass object like this innerClass ic = new innerClass(); ic.addItem("Shay"); frame.getContentPane().add(ic, BorderLayout.CENTER); (your way adds 'Shay' to a different innerClass object to the one that is added to the window!) Hope this helps, Colin.
