I would like to run a jar file extracted from my java project to be run on a Linux server I connect through SSH Tunneling. There are few problems, first there is something wrong with the Display: I get the error
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:173)
at java.awt.Window.<init>(Window.java:437)
at java.awt.Frame.<init>(Frame.java:419)
at java.awt.Frame.<init>(Frame.java:384)
at javax.swing.JFrame.<init>(JFrame.java:174)
at random_v2.v2Frame.<init>(v2Frame.java:127)
at random_v2.Wrapper.main(Wrapper.java:25)
and second is that I am not sure if I have to install other applications as well. In my code, the java program needs to get run other applications like weka, do I have to install weka with the same directory name and specs that is in my mac? I appreciate your help in advance. Best wishes

Assuming you're tunneling into this unix box using PuTTY:
Make sure X11 forwarding is enabled in your PuTTY settings.

Connect via command line using this command:
ssh -X user@server
The -X option enables X11 forwarding.
