Problem with jar

[kop]

Hello

I tried to run a jar file from cmd but it said me this:
Exception in thread "main" java.lang.NoClassDefFoundError: Ψjar
Caused by: java.lang.ClassNotFoundException: Ψjar
at java.net.URLClassLoader$1.run(Unknown Source)

at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: έΑΥjar. Program will exit.

What could I do?

Is there a variable with a null value at line 32?
