1. Problem

After installed the JME (Java Mobile Editon)/J2ME (Java Micro Edition) in My OS/Ubuntu, But when launching “/home/dnd/WTK2.5.2/bin/ktoolbar” (without quotes) in the terminal is supposed to bring up the JME (Sun Java Wireless Toolkit manager GUI), but instead you get the following error:

dnd@riyaniezt:~$ /home/dnd/WTK2.5.2/bin/ktoolbar
