I've just got Java Micro Edition (WTK 2.5.2, I think) working on my Ubuntu machine. I can use the phone simulator to simulate a "Hello world" app, but once this is transferred over to my phone (http://www.dealextreme.com/details.dx/sku.44402) it says "invalid application file"
This is a slight problem, and a solution will be greatly appreciated.
