Hi,

I'm trying to do a simple game in J2ME using just two simple .png for a
sprite and a tile background. It all works fine on the J2ME Wireless Toolkit
but when i go to download it onto my Nokia 3220 i just get application
error - Null Pointer java/lang/NullPointerException msg's

any simple solution - assuming its probs with loading picys.

Thanks

somebody else is having this exact same problem in another newsgroup.
Try looking up the thread there.

Does your Nokia print out a stack trace with file names and line
numbers?

Handsets generally don't do that: not enough screen real estate.

Not being familiar with handsets, I was thinking maybe the OP could
reproduce the error in some sort of emulated environment, or perhaps the
error log would be saved to a file that could be downloaded later or
something like that.

Did you check your JAR file to make sure the images are there?
