ImageIO problem

Question

I have the following lines in my program :
if (new File(Item_Image_Path).exists())
BufferedImage Buffered_Image=ImageIO.read(new File(Item_Image_Path)); // "C:/01_Pictures/GX910120.JPG"
Image_Width=Buffered_Image.getWidth();
I got an error message, because I got a null for the Buffered_Image, how can this ever happen ? I looked at the value for : Item_Image_Path, which is : "C:/01_Pictures/GX910120.JPG"
This image exists on my PC and I can double click and open it.
There is a twist though, it was working correctly until I packed all my programs into a Jar file, and in my program I let it load all classes and delete the jar when it executes, I thought since all the classes are loaded, there shouldn't be any problem, all other classes seems to wok fine, it just can't load images, does anyone know why this happened ?

Answer 1

Thanks for replying, I'll try that, does that work with absolute path, such as : "C:/Dir_Image/..." ?
But I still don't know why it went wrong only after I forced it to load all classes and then delete the jar ? That means there was no problem in finding the images with my code, even after I packed all classes into a jar and run from that jar it was working fine. It went wrong only after I deleted the jar, so there must be some classes that didn't get loaded before the jar was deleted, I went through the jar file and called Class.forName() on all the classes in the jar, what could be missing that caused it to be unable to load the resources ?
