h2. Installling/Deploying with the Petals ESB Autoloader

To install/deploy a JBI artifact, just put its associated archive in the installation/deployment directory (identified by the property {color:red}{{petals.autoloader.XXXXXX}}{color}. {{petals.autoloader.path.install}}. It will be automatically installed/deployed after a delay lower than the value of {{petals.autoloader.scan.period}}, and moved in the uninstallation/undeployment directory.

+Note 1:+ If a JBI artifact is installed/deployed by another process, using the JMX API for example, the autoloader is notified and the associated JBI archive is put in the uninstallation/undeployment directory, so it will be possible to use the Petals ESB autoloader to uninstall/undeploy the JBI artifact.

h2. Uninstallling/Undeploying with the Petals ESB Autoloader

To uninstall/undeploy a JBI artifact, just remove its associated archive from the uninstallation/undeployment directory (identified by the property {color:red}{{petals.autoloader.XXXXXX}}{color}. {{petals.autoloader.path.installed}}. It will be automatically uninstalled/undeployed after a delay lower than the value of {{petals.autoloader.scan.period}}.
If a JBI artifact is uninstalled/undeployed through the Petals ESB autoloader and has another JBI artifacts depending on it, they will be automatically uninstalled/undeployed.

+Note 2:+ If a JBI artifact is uninstalled/undeployed by another process, using the JMX API for example, the autoloader is notified and the associated JBI archive is automatically removed from the uninstallation/undeployment directory, without trigering another uninstallation/undeployment ;).
