Kindlet Dev SOS: Main class not found

I'd love to attempt to write a Picross kindlet, but I can't even get a basic "Hello World" to run. However I try to package it, I get a "Main class not found" error. What the heck am I doing wrong? Thanks in advance for your help.

FYI, I'm on a Paperwhite running 5.3.3.

Here is the current version of my kindlet: http://www.mediafire.com/download.php?dbvb7oxe1eddne0

Which Hello world. From where. Building with what. Eclipse? Ant?

What OS. Do you know java? etc...

I looked at your package.

Main-Class: HelloTest.Main

shouldnt that be at least... HelloTest/Main.class

I dont see a file named HelloTest.Main ?

stuff like that.

It's my own version of a hello world. I'm on Ubuntu without an IDE. And as to the Main-Class, package folders are separated by dots, not slashes, wherever I've seen them.

Right. fair enough.

I'm not arguing. point it at a file that exists then.

There are several hello worlds out there. not to mention a few decent example fuller apps and big long wiki entry.

I have written a fair few test kindlets now. basic but they ran. on a 3 and 5.
That misdirected call the the main class is the first glaring error. Hope that helps.

First: *use* an IDE. They're good.

Second: package names should be all lowercase, not camel-case. This might be the reason why your program fails (but probably isn't).

Third: You're not overriding any of the methods of AbstractKindlet. So even if your Kindlet did start, it wouldn't do anything.

Fourth: Otherwise, your META-INF/MANIFEST.MF looks ok (at first glance), but I don't have any device around right now to do further testing. Fix the abovementioned problems first...

And, as twobob said, you might be better off starting from a known-working hello world example.
