I did open it with terminal. I got an error stating that I didn't mark it as executable, however I did.
edit: Then, after redownloading it 5 times, it finally recognized it was executable, though it gave me an error, stating:
Code:
Exception in thread "main" java.lang.NoClassDefFoundError: /home/alex/Desktop/JavaRefresh/jar

Could not find the main class: /home/alex/Desktop/JavaRefresh.jar. Program will exit.
edit2: Nevermind, I got it working, forgot that in terminal you need to say "java -jar" and then the filepath. Now then, it insists on using port 6112. Is there any argument we can use to modify it? My router refuses to open 6112, so I have to resort to 6113.
