Java Server Application Archetype


Supports only deb and rpm packaging. No support for Windows or macOS

In the Java Application Archetype section we described how to build and customize settings related to an application. The server archetype adds additional features you may need when running your application as a service on a server. SBT Native Packager ships with a set of predefined install and uninstall scripts for various platforms and service managers.


The JavaServerAppPackaging archetype depends on the Java Application Archetype and adds the following features

  • daemon user/group support
  • default mappings for server applications * /var/log/<pkg> is symlinked from <install>/logs * /var/run/<pkg> owned by daemonUser
  • etc-default support



Everything else works the same way as the Java Application Archetype.


If you want your application to be registered as a service enable a Systemloaders plugin.

Settings & Tasks

This is a non extensive list of important settings and tasks this plugin provides. All settings have sensible defaults.

User to start application daemon
UID of daemonUser
Group to place daemonUser to
GID of daemonGroup
Shell provided for the daemon user
Home directory provided for the daemon user
Filename stdout/stderr of application daemon. Now it’s supported only in SystemV

Default Mappings

The java server archetype creates a default package structure with the following access rights. <package> is a placeholder for your actual application name. By default this is normalizedName.

Folder User Permissions Purpose
/usr/share/<package> root 755 / (655) static, non-changeable files
/etc/default/<package> root 644 default config file
/etc/<package> root 644 config folder -> link to /usr/share/<package-name>/conf
/var/run/<package> daemon 644 if the application generates a pid on its own
/var/log/<package> daemon 644 log folder -> symlinked from /usr/share/<package>/log
