Java Engine software stack is an image of a base CentOS template by Jelastic PaaS with the preinstalled JDK. It provides a bare minimum required for Java application hosting, while ensuring compatibility with all of the platform features (e.g. automated vertical and horizontal scaling, public IP, isolation groups, firewall rules, API and SSH access, etc).
