Chapter 12. Configuring the Hot Deployment System

Standalone containers will automatically load and deploy OSGi bundles artifacts from a pre-configured folder. It scans the folder once a second for new bundles. You can change the folder a container scans and the scan interval by editing properties in the org.apache.felix.fileinstall-deploy PID.

By default, a container scans the deploy folder that is relative to the folder from which you launched the container. You change the folder the container monitors by setting the felix.fileinstall.dir property in the rg.apache.felix.fileinstall-deploy PID. The value is the absolute path of the folder to monitor. If you set the value to /home/joe/deploy, the container will monitor a folder in Joe's home directory.

By default containers scan the hot deployment folder every 1000 milliseconds. To change the interval between scans of the hot deployment folders, you change the felix.fileinstall.poll property in the org.apache.felix.fileinstall-deploy PID. The value is specified in milliseconds.

Example 12.1, “Configuring the Hot Deployment Folders” shows a configuration editing session that sets /home/karaf/hot as the hot deployment folder and sets the scan interval to half a second.

JBossFuse:karaf@root> config:edit org.apache.felix.fileinstall-deploy
JBossFuse:karaf@root> config:propset felix.fileinstall.dir /home/karaf/hot
JBossFuse:karaf@root> config:propset felix.fileinstall.poll 500
JBossFuse:karaf@root> config:update
