Did you try it in 1.3.1. for the first code that you had?
I mean the one without the Tokenizer?
String abc = MainFrame.abc;
comps.split(","); might return a String, not a String array.
Anyway, perhaps the problem is in your addItem() method.
Hi,, Yes i did try it in 1.3.1. for the first code.
As i know, String.split() were from SE distribution since version 1.4 and above so java jdk 1.3.1 didn't have that functionality.
