So yeah, I just tried making a .jar file. It seems to work, the point of entry is working correctly, except it doesn't seem to be able to read the images (The background is gray). The images are in their own package, and i double checked to make sure that the images were being exported. I downloaded the Fat-Jar plugin for Eclipse to see if that worked. Now this is the weird part. If I double click on the .jar file within Eclipse, then it is gray. If I open the actual folder through Windows and double click the .jar file, it works!! And if I copy it to the Desktop, it doesn't work.

Everybody's help is greatly appreciated!

yeah i already had that page open...

i'm trying it, but with little success. I don't have too much experience with cmd. I know the basics, but I am still a noob.

right now its telling me "Failed to load Main-Class manifest attribute from " the jar file.

I made a manifest.txt file with

Main-Class: finale.finaleApp

And i made sure that it had an empty line below it. I double checked my command line stuff. Any ideas?

well.. you can use a simple winzip utility tool.. if you know how to make a winzip archive then thats how to make a jar archive..

1. Add all your resources.. your root folder which contain all the directory needed by your program into one .zip archive.

2. rename the .zip file into .jar..

that workz perfectly for me..

correct me if i'm wrong, but that is just compressing the files. I am trying to make an executable .jar file.

btw, i finally managed to make a .jar file using command line stuff. Unfortunately, I am getting the exact same result as the .jar file I created using both the Eclipse built-in .jar builder and the Eclipse Fat Jar plugin. The .jar file doesn't seem to be able to open the images and stuff.

huh? I don't understand what you mean. what file?

Well I mean I did create a manifest.mf in a META-INF folder, which finally allowed me to make a .jar with the entry point working, but I dont' understand what you meant.

when you double click on a .jar the system look for the file manifest.mf to find what the main class is
if your file is named manifest.txt it won't find it

add a System.out.println in every loading images code you have.. then when testing the jar file open the console.

that's a good way to test if the images does load..or you have a directory problem. blink.gif
