Run the bat file outside the jar file folder

Question

I have a jar file and a bat file inside the same folder. I created the jar file from the Eclipse by using export

In the bat file, I have the code like this below

java -Xms512M -Xmx512M -jar main.jar -o true
PAUSE

I can run the jar file no problem because it is in the same folder. However, if I place my bat file let say on my desktop, I cannot run the jar file. I am wondering is there a way to run my bat file without running it inside the same folder of the jar file?

Answer 1

Just replace the main.jar with the absolute or relative (ie from the location of the bat file) path of the jar file.

using absolute path:

bat file like this:

java -Xms512M -Xmx512M -jar C:\Users\admin\workspace\Main\main.jar -o true
PAUSE

using relative path:

bat file in C:\\Users\\admin\\Desktop like this:

java -Xms512M -Xmx512M -jar ..\workspace\Main\main.jar -o true
PAUSE

Answer 2

In the batch file you can change to the directory before executing the command.

cd ..\workspace\Main
java -Xms512M -Xmx512M -jar main.jar -o true
PAUSE

If you want the current working directory to remain in the location of the batch file add setlocal before changing directory

setlocal
cd ..\workspace\Main
java -Xms512M -Xmx512M -jar main.jar -o true
PAUSE
