Weird problem with distributing .jar
I posted this in another forum but was told to move the subject here.
I've created a small java application in Netbeans as a "proof of concept" to see if I could do something before proposing it to a client, but I'm running into a weird error.
I can compile a good .jar file that runs perfectly, and I can copy the "dist" folder anywhere and it works. However, if I package it with an installer (Astrum Install Wizard) and run the unpackaged .jar, it fails to run (the command line gives me a couple "NullPointerException" errors).
However (this is what confuses me), if I take the same "dist" folder as created by my installer, and copy it to my desktop, the .jar runs fine.
I'm not sure if this is the right forum (moderators feel free to move this thread if so), but what is causing this? The same file that is unzipped by the Install Wizard works fine if I do a "copy + paste" somewhere else (its not the location, I've tried installing it in a couple different places) it just doesn't like to work if I use the wizard.
