When I double click on a .jar nothing happens. I was able to open them a week ago but now nothing.
Things I have tried so far:
- reinstalling both JRE and JDK
- Running jarfix.exe
- creating a .bat file
.bat file
When I create a .bat file and put it in the same folder or when I try to open the .jar using CMD - as Administrator I get the same error.
This is my .bat file:
java -jar -debug <File Name>.jar
pause
And this is my error message:
(I'll provide 3 examples of 3 different .jar files)
(1)
F:\Games\RSPS\Tools\Displee>java -jar -debug "model_editor_1.4.1.jar"
Error: Could not find or load main class etc.Main
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application
F:\Games\RSPS\Tools\Displee>pause
Press any key to continue . . .
(2)
F:\Games\RSPS\Tools\RSPSi\RSPSi>java -jar -debug Editor.jar
Error: Could not find or load main class com.rspsi.LauncherWindow

(3)
F:\Games\RSPS\Tools>java -jar -debug bsp-3.0.4.jar

CMD
When I open CMD and type
java -version
I get this:
C:\WINDOWS\system32>java -version
java version "17.0.1" 2021-10-19 LTS
Java(TM) SE Runtime Environment (build 17.0.1+12-LTS-39)
Java HotSpot(TM) 64-Bit Server VM (build 17.0.1+12-LTS-39, mixed mode, sharing)
and when I type
ftype | find "jarfile"
I get this:
C:\WINDOWS\system32>ftype | find "jarfile"
jarfile="C:\Program Files\Java\jdk-17.0.1\bin\javaw.exe" -jar "%1" %*
It seems as if everything should be working properly but unfortunately it is not and I don't know where to go from here which is why I turned to all of you. I just want to remind you that
- all .jar files would open for me a week ago
- no .jar files will open now
- I have been using Eclipse and IntelliJ
