Is it possible to install JRE8 & Tomcat Server 8.5 in order to run .war file (Java web application) as a custom app. on opalstack?
MisyeMonji Sure, you can run your Java apps here!
We've already got JRE8 installed, so you just need to set up Tomcat running on a "proxy port" app's port assignment.
You're very welcome!
