OK, let's start by eliminating the low-hanging fruit

1. What's the download URL

2. How certain are you that it's a j2me (CLDC profile) app that someone, somewhere else in the world has manged to successfully run on a Touch?

#2 is important, because NoClassDefFoundError means the JVM launched, and attempted to load the necessary classes for the app, but at least one was missing.

Here's the rub: J2ME is about as "standard" as BASIC was 25 years ago. Meaning, the syntax is basically the same, but every single implementation of it is different in lots of little ways that matter a lot. For example, some apps depend upon JSR-xxx libraries to do things like 3D graphics, image capture, video, GPS, etc. The problem is, 99% of those libraries are proprietary to the phone itself, and basically don't exist as third-party products.

If you don't know of anyone who's ever successfully gotten it to run on a Touch, the next thing you need to do is figure out EXACTLY which JSR (see http://jcp.org/en/jsr/overview ) library/ies it needs & post the list here. While you're at it, does the error you're seeing (NoClassDefFoundError) have any details anywhere (like a specific class, stack trace, etc)? That might help pinpoint exactly what's causing it to die right now (though there's no guarantee that there aren't two dozen more just like it waiting in line behind it for their turn to die instead).
