Slick Forums

I've been programming an turn based strategy game with Netbeans using slick2d library. It runs properly when running it with netbeans. The problem is that it doesn't run after I build it. I've added libraries and manifest file seems to be ok. When I tried to run the game from command file with command "java Verkkohakki.jar" it gives an error "Error: Could not find or load main class Verkkohakki.jar". I've searched forum and googled, but haven't found any answer.

As Netbeans tells you in the readme.txt it generates - you need to run with "java -jar Verkkohakki.jar"

Now this happens. All the library files are included in manifest.

This is because -Djava.library.path is not set in the VM arguments. There is a little info about it at the bottom of this wiki page.

Alternatively, you could move your native files (DLLs, etc) to the same folder as you run your JAR from. Ideally you should set the VM flag, though.
