Creating a shell script to run Java program

Question

I used a shell script to run a Java class. My script contains

#!/bin/sh
java -jar jobs/job.jar

These are my failed attempts to run it.

[root@]#sh testapp.sh
Unable to access jarfile jobs/job.jar

if I just do this at the command line it works fine

[root@]#java -jar jobs/job.jar

thanks.

It is not recommended to routinely run things in super user mode (aka root). — emory

The best way is to get the current dirname and get in there with this:

#!/bin/sh
cd `dirname "$0"`
java -jar ./job/job.jar

This seems like the actual right answer, because using an absolute path is not an option when you plan to move the files (or even share it)

Use the absolute path to your JAR file, e. g. /root/jobs/job.jar.
