B4J Question Trying try get b4j program to run at startup

[JakeBullet70]

Hi all.

Trying to get my b4j app to run at startup. I have read and re-read ideas on the forum and just cannot get this script to work. I can type at the command line and start the program fine.

nohup /home/jre1.8.0_91/bin/java -jar /home/cloud-kvs/CloudKvs_Server.jar > nohup.out &[]

If I use this script and check the log I get 'Error: Unable to access jarfile /home/cloud-kvs/CloudKvs_Server.jar'

Any ideas?

#!/bin/sh

Hi Jake,
did you double-checked path and filename with special regard to hyphen/underscore and capital/lowercase letters?

I have cut and pasted and know linux is case sensitive. I am doing something stupid as usual...

What is the result when you run the script from the command line?

sh /path/to/script.sh start

Sounds like a permissions issue. Do you use a different role to start the jar at startup ?

 

[JakeBullet70]

Still fails. I am not even worried about running it at startup. I just want it to work.
I am logged in as root.

Works
nohup /home/jre1.8.0_91/bin/java -jar /home/cloud-kvs/CloudKvs_Server.jar > nohup.out &

Fails
/path/to/script.sh start

Which OS? VPS?

What's the output of (root)

ls -l /home/cloud-kvs/CloudKvs_Server.jar

ls -l /home/cloud-kvs

nohup /home/jre1.8.0_91/bin/java -jar /home/cloud-kvs/CloudKvs_Server.jar > nohup.out &
