Linux RHEL 7.9 global environment vars

[JulioAlblozano]

I have a project with Jasperreports in a Redhat 7.9 linux environment and I need to use the function System.getenv("Var Name"), then I configure it in the bash_profile file, but when I use it it returns "null" , I have tried many things that they say in the forums, but nothing gives me result. I thank you for your help.

That way I configure them and I can see them, but in the report it always shows "null".

.bashrc and .bash_profile are usually just for individual users, not global.

I would put this in /etc/environment

Thanks, I did that too but it didn't work for me, I don't know what I'm doing wrong. It does not take the var

Moving this to Redhat

Are you "sourcing" the file after you edit it? (You may have to reboot)

What happens if you ...
echo $LABVANTAGE_HOMEICP

Generates the following

This is the environment file

and I have already restarted the system

It seems like, as far as the system in concerned, it's working.
Is this a python application? Is it in a virtual env?

 

[JulioAlblozano]

No, it is Java a web portal with Jboss, the call of the variable is done with System.getenv("LABVANTAGE_HOMEICP"), with Linux machine on Azure Cloud

It's my understanding Java doesn't support global variables from the system.
You could have a global class, but you would still have to define them in code
or a config file for your app. (But then it wouldn't be global)
