Application Deployment

Applications can be deployed to Payara Server in the same way as GlassFish Server 4.1 Open Source Edition. Payara Server does not modify this process but does add some new features to deployment descriptor files which are documented in the following pages.

Deploying On Server Start

GlassFish has had the ability to deploy applications on server start for a long time now, using the autodeploy directory. While acceptable in development environments, the scanner used to deploy files in this directory is a security risk for production and is therefore disabled in the payaradomain bundled with Payara Server.

To reintroduce the capability of deploying an application on server startup without the risk of enabling the deployment scanner, a feature from Payara Micro was introduced: the ability to run asadmin commands at startup, either pre or post boot.

To enable this feature, we have extended the start-domain feature to accept two extra options: --prebootcommandfile and --postbootcommandfile which can be used as follows:

Pre-boot Commands

Usage: asadmin> start-domain --prebootcommandfile=/path/to/file

Aim: passing a list of commands as a file to the server to run pre-boot. Due to the time during boot when the commands in this file are executed, this only supports set commands.

Post-boot Commands

Usage: asadmin> start-domain --postbootcommandfile=/path/to/file

Aim: passing a list of commands as a file to the server to run post-boot. This is where commands such as service configuration commands should be run.

Note

There are some important caveats to note:

  • Both files should be saved in a text format, with each command on it’s own line.

  • Lines where the first non-whitespace character is # are treated as comments

  • Any blank lines will be ignored

  • Any invalid or failing commands will be logged to the server.log and the file will continue to be processed

  • The files must exist, and be accessible from Payara Server.

  • Both pre-boot and post-boot files can be passed at the same time.
