This page covers common configuration steps for GlassFish deployments.
GlassFish runtime configuration is primarily in /opt/glassfish/glassfish/domains/domain1/config/domain.xml.
Service manager settings (if using systemd) are typically in /etc/systemd/system/glassfish.service.
Restart the service or reload the configuration using your init system or container manager.
Confirm the service is healthy, then verify an application deploy or management endpoint.
