Creating .jar File - .jar doesnt do anything

[Coold0wn]

hey guys,
i have a problem with the .jar file..
if i run the void main(String args[]) method of my main class: Start everything is working fine , and i got my programm were i can click my buttons, load images etc.
but when i create a .jar file , with Start class as main class, it takes a while until it's done and the .jar is at the folder i chose. but now if i click on the .jar... it loads for 1 sekond and then nothing happens...

do you have any idea why this could be?...
(i work with blueJ if that might be usefull)

public class Start

{
    public Start()
    {
    }
    
    public static void main(String[] agrs)
    {
          Editor e = new Editor();
    }

}

Check if there are errors:
Open a command prompt, change to the folder with your jar file and enter: java -jar <YOURJARFILENAME>.jar
To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

Der Befehl "java" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.

(= the command "java" is either written wrong or could not be found.)

edit:
i can open the .jar files of my older versions of the program.
but with the new ones... it doesnt work anymore.
and i can also create new .jar files with my older versions, which are able to run.

i tried to open a old projekt and change everything so it would be like my new one... but then it didnt work anymore...

Your java installation hasn't put the java command where it can be found by the OS.
For testing you can use the full path. Find the location of the java.exe file and use that vs just java. For example:
C:\Java\jdk_???_?\bin\java.exe -jar JumpNrun.jar

i found my Java at c:\Program Files(x86)\Java .. but i cant run the java.exe in the bin folder, because there is " " (space) after Program
... and if i just run the java.exe it wont do anything

edit: i dont even know if there is an error... to me it seems like the .jar file just wouldnt do anything...
and there is no error if i run the program via BlueJ..
and the images i have, are in the folder with the .jar too


ok it worked.. a friend of mine helped me:
