Hi and welcome to the Mageia-forum torinese24!!!!

Your topic has been moved to the "Basic support"-forum.

hello, thanks
could you help me?

Well i guess you need to have Java installed.

Can you give the output in console of:

Code: Select all

rpm -qa | grep java

and after I do this command
What should I do?
Java already installed

You should be able to execute those .jar-files with

Code: Select all

java -jar your.jar

where your is of course the name of the .jar-file you want to run.

me an error
I said:

Unable to access jarfile minecraft.jar

"minecraft.jar" is the game

Al-right torinese24, i am out of options, sorry.
You have to wait until more advanced knowledge is around.

You should maybe give the fully qualified path to the jar file in the java-command.

And please copy&paste the command used and the output this produces, also from which path you executed it from.

minecraft.jar = game
procedure:
java-jar minecraft.jar

Error: Error: Unable to access jarfile minecraft.jar

the game (minecraft.jar) is located on the desktop (do not know how to say in linux, but is found in the desk

ciao,
go to mageiaonline if you prefer use italian


minecraft.jar works fine here

tom@localhost Desktop]$ java -jar minecraft.jar
asdf
(then a windows pop up)

these are the installed java packages on my machine:
(Isadora asked you this list to see what you have on your machine)

Code: Select all

tom@localhost Desktop]$ rpm -qa | grep java

I like using the terminal, put the path where the file open?

open the terminal, then type these commands:

Code: Select all

cd
cd Desktop (maybe you have Scrivania)
java -jar minecraft.jar


Code: Select all

java -jar ./minecraft.jar

would be better

~edited by moderator, command-output placed between [code]-tags.

this means it started, but there are some problems in it.

As it works on my PC,
so you should check if you have my same Java packages
