Re: Minecraft and Java

YES! It's working!
Thanks man.
It's working fine but after I entered the command it printed this in the terminal:

harry@Harry-Netbook:~/Desktop$ java -jar minecraft.jar

Re: [SOLVED] Minecraft and Java

Hi, I'm a little new to Kubuntu and not very versed with Linux in general but am a fairly advanced computer user, however I think I may have done something wrong here. I put in the code in as written, and when I try to execute my minecraft.jar I get this...

dave@dave-Veriton-M460:~/Downloads$ sudo java -jar minecraft.jar

Any help you could provide would be greatly appreciated

Re: [SOLVED] Minecraft and Java

First, you shouldn't need to execute this command using sudo.

Second, look at the top of this page at reply #15. Same "error" message. These are errors that developers might use but are entirely meaningless to us normal users.

Am I wrong in assuming that the game still runs? And don't use sudo.
