Creating a shell script to run a 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 unsuccessful attempts to launch it.

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

if i just do it on the command line it works fine

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

thanks.

Answer 1

Use the absolute path to your JAR file, for example. /root/jobs/job.jar . /root/jobs/job.jar .

Answer 2

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

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